[PHP] Re: If statement question
Alex Major wrote:
Hi list.
Basically, I'm still learning new things about php and I was wondering if
things inside an if statement get 'looked at' by a script if the condition
is false.
For example, would this mysql query get executed if $number = 0 ?
If ($number == 1) {
mysql_query($blah)
}
I know that's not really valid php, but hope it gets my point across. I was
just wondering from an optimisation perspective, as I don't want sql
commands being executed when they don't need to be (unnecessary server
usage).
Thanks in advance for your responses.
Alex.
Stuff inside an if statement will be compiled (So it has to be free of
syntax errors and such), but it won't be executed unless the condition
is true.

Re: [PHP] Equivelant to mysql_fetch_row for normal array

Jochem, Tul, Nicolas,
Thank you for your help.
I must be doing something wrong with how my array is generated. It's
actually just a MySQL result, but because it is returned from a
function, it does not seem to behave as I would expect a MySQL result
should.
I'm trying the foreach function and key values, but I'm clearly not
quite getting it right. Perhaps there is something about my code which
is wrong. So I'm presenting what I hope is all the relevant parts:
public function getData($row, $type, $column, $match) {
$query = "SELECT " . $row . " FROM " . $type . " WHERE " .$column . " =
" . $match;
echo "query = " . $query . "";
$result = mysql_query($query);
$data = mysql_fetch_array($result);
return $data;
}
foreach($elements as $key => $val){
echo "val[type] = " . $val[type] . "";
echo "val[resource] = " . $val[resource] . "";
}
What I'm getting back doesn't make sense. I can't go all the way into my
code, but $val[type] should be a string value containing the words
"Article" or "Text".
But instead, I get:
val[type] = 2
val[resource] = 2
Am I still not doing the foreach correctly?

Dave M G
First of all, you're using invalid syntax. You should have $val['type']
rather than $val[type].
Second of all, mysql_fetch_array returns only a single row, $elements.
This is an array. From there, you're asking foreach to return each
element of the array as $val. So each time through the foreach loop,
$val will have the contents of that element. The element isn't an array,
it's a scalar. So you're taking a scalar and trying to treat it like an
array.
You really should read the manual, the pages for all these functions
describe EXACTLY what they do.
Remember that mysql_fetch_array returns an associative array. You can
refer to the SQL fields by their names. So if your select query was
"SELECT foo, bar FROM mytable", after doing a mysql_fetch_array you
could do this:
echo $row['foo'] . "";
echo $row['bar'] . "";

Operators such as == support strings for a reason, people should use them as such. You shouldn't rely on what other languages do, but the one you're working with; PHP has no explicit data-types and manages strings as PERL does. Just as you say there's a reason why "==" supports strings, there's also a reason (or more) for strcmp() to exists --it's just safer to use strcmp() instead of "==", e.g: 24 == "24/7" Safer, yes. And it'd be even better to do 24 === "24/7", in which case you don't need a function call, it's probably faster (I'd imagine that comparing equality is faster than finding out HOW close it is like strcmp does), and as I mentioned, easier to read. If you need to ensure type, (so that 0 == "foo" doesn't return true), then you can use ===. Using a function call that does more than you need when there is an operator to achieve the same goal is bad advice. I think you haven't encounter a "special case" to make you understand "==" does NOT have the same behaviour as strcmp() It's just like the (stranger) case of the loop for ( $c = 'a'; $c <= 'z'; $c ++ ) echo $c; I didn't say that it had the same behaviour, only the same goal; finding out if two strings are equal. strcmp does MORE than that, it also finds out how CLOSE they are. You almost never need that information, in which case you're wasting processing time with a function call that does something that you don't need. Come on, face it, how many times have done anything with strcmp's return value OTHER than checking that it's zero? I bet the cases are fairly rare. Not to mention the fact that it leads to harder to read code. Which of these has a more readily apparent meaning? if ( strcmp($foo,$bar) == 0 ) if ( $foo === $bar ) That might be true, either way you need to know the language to understand what the first line does and that the second isn't a typo. === is a basic operator. One has to assume that somebody writing code is at least familiar with the basic operators. If not, well, asking them to know what the function strcmp does and what it means when it returns zero is just as onerous. If not more so. And again, strcmp wastes time calculating information we don't NEED. Regards, Adam. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If you really want to keep the p?name syntax, I would suggest throwing them in
an array with keys.
$arr["p1name"]
$arr["p2name"]
Then that way you can create the key dynamically:
$arr["p".$i."name"]
Not pretty, but it works.
Thanks,
I haven't checked this, but couldn't you reference it as $arr["p$iname"]
? Is there a reason why variable expansion wouldn't work in this

If it does, you could make it easier to read by doing $arr["p{$i}name"]
even though the {} aren't required. It'd be a lot easier to read than
concatenations :)

[PHP] Re: shutting down a web app for maintenance
Shutting down Apache would do the trick ;) But if you're in a shared hosting environment that may not be possible. As for sessions, it depends how you track them. You can't kill all PHP sessions in one go, but you could have your web app nuke the sessions of users after they come back after maintenance. Something like first_login_after_maint in the database, that if set to true, mandates that any existing session data be destroyed before continuing. I assume that the reason you want to kill session data is because the data and how it is used would be different after the maintenance? Because otherwise, if you've denied all access to ANY of your webapp's php scripts, it shouldn't matter if the user has session data. If you physically move the web app's PHP scripts (Or set up a redirect, etc), they can't do anything with it. Regards, Adam Ben Liu wrote: Thanks Adam, What you say makes good sense to me.

Querying all data in the first place is a waste, and the practice of
seeking through a dataset seems silly when MySQL has the "LIMIT" feature
to specify which data you want to return.
I believe the proper way to do this would be something like this
(Simplified example, of course):
$query = "SELECT SQL_CALC_FOUND_FOWS * FROM foo LIMIT 30, 10";
$result = mysql_query($query);
$query = "SELECT found_rows()";
$num_rows = mysql_result(mysql_query($query), 0);
That should be much faster than the methods used by either of you guys.
As a comment, it would have been better to do "SELECT COUNT(*) FROM foo"
and reading the result rather than doing "SELECT * FROM foo" and then
mysql_num_rows(). Don't ask MySQL to collect data if you're not going to
use it! That actually applies to why you shouldn't use mysql_data_seek
either.

Or something like that. I'm not exactly sure what your criteria are.
What I'm doing above is looping through the mail messages one at a time,
and checking all aspects of that email in each loop iteration. If you're
doing complex analysis on each message, then that is probably the
fastest way.
If you're simply searching for things, you could always do array
searches. So, search through $email with array_search or perhaps
array_intersect. Then you don't need to loop at all.

[PHP] Re: Replacing text with criteria
Jeff Lewis wrote:
I have been working on a script to parse a CSV file and in the process I
clean out a lot of the garbage not needed but I am a bit stumped on one
aspect of this file. It's a list of over 3000 contacts and I'm trying to
mask a lot of the information with *.
So as I loop through this list I am checking the array elements as if I find
a phone number (555) 555-1212 (I was searching for the (555)) I want to
convert it to (555) ***-
For fields not containing an area code, I wanted any text to be replaced by
an * except for the first and last letter in the element.
I'm stumped and was hoping that this may be something horribly simple I'm
overlooking that someone can point out for me.
This will take a string and replace everything but the first and last
characters.
$string = substr_replace($string, str_repeat("*", strlen($string)-2), 1,
-1);
It seems like you want to do it based on letters though, so "Hello,
World!" would become "H**d!", not ""H***!" (which the
above would do). To do this you'll need to get the positions of the
first and last letters in the string and use those instead of 1 and -1.
Off the top of my head I don't recall any functions that can do this,
strpos and strrpos don't take arrays as parameters. You may be better
off with regular expressions for the actual replacement unless somebody
knows of a function to get the positions.
BTW, in functions like substr, specifying "-1" for length means keep
going until the second to last character.

Stream_get_meta_data() does not do it; in my tests, its output does not change even when the server closes the stream. Thank you, Michael W. If it is a network socket, and the remote end disconnected unexpectedly (which you MUST assume is a possibility), then the only way to find out if the connection is still open is by SENDING data. Just trying to read it won't cut it. The thing to understand is that when a remote client/server disconnects, it normally safely closes the socket and notifies you. But an abrupt disconnection (Something crashes, loses connectivity, etc) sends no such thing. The only way to find out that a connection is really lost is to write some data and see if it times out or not.

You might want to reexamine the need for your code. It appears that all
your code does is searches through a file for a certain line. Do you
need to do this manually? array_search() will replace your entire for

Okay, so I found out it's limitations and quirks.
But, you must admit that it is confusing to have a loop that goes from "a" to "z" and considers
"aa" but not "aaa".
Now, if the loop just went from a to z, then I would think that would be logical. But I fail to see

I know this discussion doesn't need to continue any further..hah.. but I think
the biggest confusion people are having is that they're looking at two things
and assuming that PHP operates the same on both and these two things serve
different purposes.
1. Incrementing strings: Best example giving was "File1"++ == "File2" or "FileA"++ ==
"FileB". In that case, wouldn't you want it to go from FileZ to FileAA? Makes sense right?
2. Comparing "greatness" of strings: Rasmus mentioned this earlier, but I
wante to illustrate it a little more because I think it was overlooked. If you have a
list of names, for instance, and you alphabetize them, you'd get something like this:
Bob
Brendan
Burt
Frank
Fred
Just become a name is longer doesn't mean it comes after the rest of the names in the list. So in that vane,
anything starting in "A" will never be > something starting with a "Z". a < z aa
< z aaa < z because:
a
aa
aaa
z
When using interation and a for loop and " <= z" it gets to "y" and it's true, gets to "z" and it's still true, then
increments to "az" and yup.. still < "z". As mentioned, it's not until you get to something starting in "z" with something
after it that you're > "z".
So hopefully that makes a little more sense.

If you're going to be using 5.1.2 in production, develop on 5.1.2. PHP
doesn't guarantee backwards compatibility, especially in such a big
change as 5.0.x -> 5.1.x. Better to develop on 5.1.2 from the start than
to develop on 5.0.5, put the code on 5.1.2, get a bunch of errors, and
then have to develop again on 5.1.2 to fix the bugs. Not to mention that
any testing done with 5.0.5 is invalid since you can't be sure that
things will behave the same with the different production version. You
may even waste time working around bugs in 5.0.5 that don't exist in 5.1.2.

Umm. As I said, just use file_get_contents():
$file = file_get_contents("http://www.tryout.com/1/2/";);
Assuming allow_url_fopen is on.
If not, you could try using curl - see http://www.php.net/curl
allow_url_fopen is on by default, and curl requires custom compile-time
options. Considering that, it is logical that if the user can't enable
allow_url_fopen, they're not going to be allowed to recompile PHP.

HTML can't be parsed line-by-line since even a single tag can be broken
up onto multiple lines. And also, "if ($line[85])" simply checks if
there is a character in position 85 of the line. It looks like your code
is reading in a file, checking if each line is at least 85 characters
long, and then writing it out again.
I suggest you read in the whole file using file_get_contents(), and then
do the regex matching or strpos matching that I described in my previous
message. Also keep in mind that as of PHP 5 there is a
file_put_contents() function that lets you dump out a file in one go
(with higher performance than doing it yourself). php_compat also has a
copy of that function for other versions of PHP, although of course they
do it in PHP code so the performance benefits are slightly less.

Alternatively, you could do this with strpos(), since it lets you specify where to START searching from. It might be faster, but it would probably end up being less flexible. Alternatively, if you need a super robust solution, you might want to look into actual HTML parsing libraries, like tidy (which has a PHP module).

$xml = simplexml_load_string(file_get_contents("http://ba.com/foo.php";);
Alternatively, if you don't want the PHP script to be visible on the web
server, make it executable (with a shebang) and then execute it and pass
the output to simplexml_load_string(). You know, using shell_exec() or
the backticks operator.
Note that simplexml_load_string() doesn't care about what type of file
you reported it as (with Content-Type or something). It only cares that
the string you pass it is XML. So if your script is the ONLY one that
will ever get this XML, you don't need to bother with the content type.

That is incorrect. There is nothing stopping a PHP script from doing
exactly what he says, and being a server-side script doesn't imply that
the data will be buffered.
I suggest that both of you examine the contents of
http://www.php.net/manual/en/function.flush.php for more information on
obstacles to getting data to the client as it is generated.
As an unrelated note, there is no point in using "print" for some things
and "echo" for others. For your uses, you might as well just use "echo"
for everything.

Essentially you want pcntl_fork(), although you might want to use
something like stream_socket_pair() to do interprocess communication.
You should be able to find all the documentation and examples you need

I'd say that if you're worried about overrunning PHP's output buffers, you have more serious design issues with your script. In itself, it isn't a memory leak; PHP always flushes all buffers when a script terminates. AFAIK this is the default behavior with output buffering enabled; PHP buffers all script output and then flushes it when the script terminates. I have no idea if PHP is smart enough to flush the buffer if it fills up. But seriously, this shouldn't be an issue; break your data up into more manageable chunks so that you aren't trying to cram 4MB of HTML into some poor user's browser.

**NEVER** use regular expressions for simple search/replace

simple string replace, and you should not use regular expressions for that.
I am assuming you want to remove the ! and ? and not replace them with a
space. In this case:
$str = str_replace(array("!". "?"), "", $str);
Or if you did want to replace them with a space:
$str = str_replace(array("!". "?"), " ", $str);
This is especially important if you're doing the string replace in a
loop, but even if you aren't, it is very bad style to use regular
expressions for such a simple replacement.

Cheers, Micky -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php I built something similar to the situation that you are describing.

I know I'm entering this discussion a bit late, but one tool that I've found indispensible in writing regular expressions (even after knowing how to write them) is The Regex Coach (http://www.weitz.de/regex-coach) (Free, and runs on Windows and Linux). Essentially, you paste the text to search into the bottom textbox, and then start typing your regular expression into the top one. As you type, it shows you what it is matching in the bottom one. It can also show you what individual submatches are matching, and all sorts of neat stuff. So, if I have an HTML web page and I want to suck some specific information out of it, I'll paste the information in, write up a regex, and make sure it's matching what it's supposed to. But the feedback AS you're typing it is super handy. For example, if I have a regex, and I add a "[a-z]", then the indicator will show it matching the next character, then if I add "*", the text selection will expand to show it matching the rest of the letters, and so on.

[PHP] Re: str_replace(), and correctly positioned HTML tags
Dave M G wrote:
PHP list,
This may be a simple matter. Please feel free to tell me to RTFM if you
can direct me to exactly where in the FM to R. Or, alternately, please
use simple explanations, as I'm not an experienced PHP coder.
I'm building a simple content management system, where users can enter
text into a web form. The text is stored in a MySQL database. The text
should be plain text.
When the text is retrieved from the database for display, I want to add
some HTML tags so I can control the format with an external CSS.
I'm assuming the best way to do this is with str_replace(). But there
are some complications which make me unsure of its usage.
First, here is the code I initially made:
$content = "" . str_replace("\r\n", "\n", $text) . "\n";
echo $content;
The problem is that I want to give the users the ability to add text
that will be converted to tags. I figure the best and easiest way
to do this is give them some text markers, like "--++" and "++--" that
can be converted to and respectively.
So I guess I do:
$content = str_replace("--++", "", $text);
$content1 = str_replace("++--", "", $content);
$content2 = "" . str_replace("\r\n", "\n", $content1) . "\n";
echo $content2;
But of course a user is likely to put their heading at the
beginning of their text. Which would generate:
Headingtext text text
That's not good. What I need is:
Headingtext text text
And figuring out how to do that was where my brain stopped.
I need to be able to account for circumstances where it may not be
appropriate to arbitrarily put a tag at the beginning.
As well as tags, there may also be things such as images and
lines, but they are all similar in that they will take some text code
and convert into an HTML entity.
I need to be able to separate those out and then be able to place
opening and closing tags at the right place before and after
paragraphs.
Is there a way to do this? Is there a good tutorial available?
Any advice appreciated. Thank you for taking the time to read this.

Dave M G
It seems like your life would be a lot easier with break takes instead
of paragraph tags. Break tags behave like newlines, so work rather well
for a 1 to 1 correspondance when turning \r\n into . This way, you
don't have to worry about the opening tags.
The fastest way to do this may be the function nl2br(), which takes only
one parameter, your string, and returns your string with the newlines
replaced by break tags.
Another piece of advice is that you are creating a lot of strings. Do
you need the string $text to be unmodified? Why don't you do this:
$text = str_replace("--++", "", $text);
$text = str_replace("++--", "", $text);
$text = "" . str_replace("\r\n", "\n", $text) . "\n";
echo $text;
Remember that PHP works by value, not by reference. So what happens in
that first line is that it makes a copy of $text, does the replacement
on that copy, and then overwrites $text with that copy. With your method
you are creating a bunch of strings that I would imagine go unused later
in your script.
Since you seem to want to maintain a newline in the HTML source, nl2br
might not be exactly perfect for you. Here is your original code
modified to work with break tags:
$text = str_replace("--++", "", $text);
$text = str_replace("++--", "", $text);
$text = str_replace("\r\n", "\n", $text);
echo $text;
And here is the same code using arrays and one single replace
instruction to do it, since replacement order doesn't matter:
$text = str_replace(array("--++", "++--", "\r\n"), array("",
"", "\n"), $text);
echo $text;
And of course, if you never do anything with your formatted string
except echoing it out, don't store it, just echo it:
echo str_replace(array("--++", "++--", "\r\n"), array("", "",
"\n"), $text);
So, to sum up my advice:
1) Don't create extra variables that you will never use
2) Consider using break tags instead of paragraph tags, they're easier
to deal with in your situation.
3) Use arrays for replacement when appropriate
4) Don't store data if you're only ever going to echo it out right away
and never use it again.
I think that's it, unless I missed something.

Re: [PHP] How to disable PHP's POST caching?
Stut wrote: Adam Zey wrote: Tunelling arbitrary TCP packets. Similar idea to SSH port forwarding, except tunneling over HTTP instead of SSH. A good example might be encapsulating an IRC (or telnet, or pop3, or ssh, etc) connection inside of an HTTP connection such that incomming IRC traffic goes over a GET to the client, and outgoing IRC traffic goes over a POST request. So, the traffic is bounced: [mIRC] ---> [client.php] -internet-> [apache ---> server.php] -internet-> [irc server] And the same in reverse. The connection between client.php and server.php is taking the IRC traffic and encapsulating it inside an HTTP connection, where it is unpacked by server.php before being sent on to the final destination. The idea is to get TCP tunneling working, once you do that you can rely on other programs to use that TCP tunnel for more complex things, like SOCKS. You're trying to get a square peg through a round hole. The HTTP protocol was not designed to do anything like this, so the standard implementation by most web servers and PHP does not allow what you are trying to do. That's the fun of it, making things like PHP and HTTP do things they weren't supposed to. I'm curious about your 'lots of POSTs' solution. How are you keeping the connection open on the server-side? It's certainly not possible to maintain that connection between requests without using a process outside the web server that maintains the connections. I've implemented a system in the past to proxy IRC, MSN and AIM connections in this way, but it only worked because the requests that came into PHP got passed to this other process which held all the connections and managed the traffic. And yes, it did generate a huge amount of traffic even when it wasn't doing anything due to the need to poll the server for new incoming messages. With the lots-of-posts, the connection is a regular keepalive, which any webserver happily keeps open. When this keepalive connection closes, you open a new one. At least this way, while I still need to send lots of posts (Say, one every 100ms, or 250ms, something like that), I can limit the new connections to once every minute or two. While 4 messages per second may seem like a lot, I would imagine that an application such as Google Maps would generate a LOT more than that while a user is scrolling around; google maps would have to load in dozens of images per second as the user scrolled. Polling for incomming messages isn't a problem, as there is no incomming data for the POSTs. A seperate GET request handles incomming data, and I can simply do something like select, or even something as mundane as polling the socket myself. But I don't need to poll the server. And, the 4-per-second POST transactions don't need to be sent unless there is actually data to be sent. As long as a keepalive request is sent to make sure the remote server doesn't sever connection (My tests show apache 2 with a 15 second timeout on a keepalive connection), there doesn't need to be any POSTs unless there is data waiting to be sent. Of course, this solution has high latency (up to 250ms delay), and generates a fair number of POST requests, so it still isn't ideal. But it should work, since it doesn't do anything out-of-spec as far as HTTP is concerned. This demonstrates a point at which you need to reconsider whether a shared hosting environment (which I assume you're using given the restrictions you've mentioned) is enough for your purposes. If you had a dedicated server you could add another IP and run a custom server on it that would be capable of doing exactly what you want. In fact there are lots of nice free proxies that will happily sit on port 80. However, it's worth nothing that a lot of firewalls block traffic that doesn't look like HTTP, in which case you'll need to use SSL on port 443 to get past those checks. I wasn't targetting shared hosting environments. I imagine most of them use safe mode anyhow. I was thinking more along the lines of somebody with a dedicated server, or perhaps just a linux box in their closet. The thing is, I'm not writing a web proxy. I'm writing a tunneling solution. And, the idea is that firewalls won't block the traffic, because it doesn't just look like HTTP traffic, it really IS HTTP traffic. Is a firewall really going to block a download because the data being downloaded doesn't "look" legitimate? As far as the firewall is concerned, it just sees regular HTTP traffic. And of course, a bit of obuscation of the data being sent wouldn't be too hard. The idea here is that no matter what sort of proxy or firewall the user is behind, they will be able to get a TCP/IP connection for any protocol out to the outside world. Even if th

echo str_replace(array("am", "pm), array("a.m.", "p.m."), date("g:i a"));
which would output something like "12:52 p.m."

What kind of process are you running that would require this? That is what I am looking for. What is the real issue? What would you do that would require a stated connection? Tunelling arbitrary TCP packets. Similar idea to SSH port forwarding, except tunneling over HTTP instead of SSH. A good example might be encapsulating an IRC (or telnet, or pop3, or ssh, etc) connection inside of an HTTP connection such that incomming IRC traffic goes over a GET to the client, and outgoing IRC traffic goes over a POST request. So, the traffic is bounced: [mIRC] ---> [client.php] -internet-> [apache ---> server.php] -internet-> [irc server] And the same in reverse. The connection between client.php and server.php is taking the IRC traffic and encapsulating it inside an HTTP connection, where it is unpacked by server.php before being sent on to the final destination. The idea is to get TCP tunneling working, once you do that you can rely on other programs to use that TCP tunnel for more complex things, like SOCKS.

[PHP] Re: Going through 2 arrays at once

Greetings,
PHP Rookie here with a quick question - how do I go through 2 arrays at
once with different keys?
I'd like to combine these 2 arrays into one:
for ( $i = 0; $i < sizeof($logicalDrive); $i++) {
echo "$arrLogDrive[$i]\n";
}
for (reset($logicalDrive); $i = key($logicalDrive); next($logicalDrive))
{
echo "$i: $logicalDrive[$i]\n";
}
The first array returns things that the OID in the second array
represent. I.E. $array = array( 1=> 'Controller Index:', 'Drive Index:',
Fault Tolerant Mode:', etc, etc);
While the second has the MIB name as the key, then the return value of
the snmpget:
CPQIDA-MIB::cpqDaLogDrvCntlrIndex.0.1: 0
CPQIDA-MIB::cpqDaLogDrvIndex.0.1: 1
CPQIDA-MIB::cpqDaLogDrvFaultTol.0.1: mirroring
What I'd like to do it replace CPQIDA-MIB::cpqDaLogDrvCntlrIndex.0.1
that gets displayed into the "Controller Index:" in the other array.
I hope this makes sense. Sorry if it's super simple to solve, but I
tried a few things, and googled a few things, but I must have not found
the right thing I was looking for, as I still can't figure it out.
Thank you very much!

What, exactly, are you trying to accomplish? Skip past the persistency, etc. and describe the problem for which you are seeking a solution. I have the feeling that there may be a way to do what you want with PHP if you will describe the process. Essentially, I'm looking to write something in the same vein as GNU httptunnel, but in PHP, and running on port 80 serverside. The server->client part is easy, since a never-ending GET request can stream the data and be consumed by the client instantly. The thing I'm having trouble with is the other direction. Getting data from the client to the server. The data going from client->server needs to be sent over an HTTP connection, which seems to limit me to PUT and POST requests, since they're the only ones that allow significant quantities of data to be sent by the client. Ideally, there should be no delay between the client wanting to send data and the data being sent over the connection; it should be as simple as wrapping the data and sending. So, I need some way to send data to a PHP script that lives on a webserver without any buffering going on. My backup approach, as I described in another mail, involves client-side buffering and multiple POST requests. But that induces quite a bit of latency, which is quite undesirable.

Jochem Maas wrote: why is port 80 a requirement - HTTP can technically over any port. It must be accessible to any client, no matter what sort of firewall or proxy they go through. The only way to absolutely assure that is, as far as I know, to use port 80. It is the only port that you can count on with a fair degree of certainty, if the user is proxied or firewalled. I'd just as soon write my own simple webserver, but then it'd run into conflicts with existing webservers on port 80. My current solution is to buffer data on the client-side, and send a fresh POST request every so many milliseconds (Say, 250) over a keepalive connection with the latest buffered data. The downside of this is that it introduces up to 250ms of latency on top of the existing network latency, and it produces a lot of POST requests. I would really like to eliminate that by streaming the data rather than splitting it up like that.

You're correct, of course. I was a bit confused, it seems. PUT behaves as I described above. If you do a PUT request for the PHP script directly, the PHP script is called right away, and any attempt to fread from php://input blocks until either the client is done sending, or some sort of buffer is filled (the fread occasionally returns with lots of data if you keep sending). So, might I amend my question to, is it possible to disable PHP buffering PUTs, or Apache buffering POST? (Or is it PHP that just buffers the POST before actually executing the script, but post Apache?)

[PHP] XML and special characters
I've been having a tough time with parsing XML files and special characters. I have attempted every applicable engine, last try SAX, to attempt at parsing a (rather large, 17.8mb) xml file. The problem I hit, is when it hits a UTF8 encoded character. I've attempted at decoded the file before it hits the parser, I've attempted even ENCODING it (god knows why that'd work, it didnt, lol). I've tried html_entities, etc. Nothing as such has worked. I've also tried simply removing the character, and low/behold, it worked! Darned thing... §µÖÕÔÓÒ Those are the characters so far that have caused me problems. I'd give the utf8 encoded equivalent, but I'm not sure of it off the top of my head. My code, varies so much that I'm not sure it'd be useful to type it out. The issue seems not to be with my code, as when I parse the file manually with a whole bunch of inefficient regex statements, everything works out peachy.

[PHP] Schroedinger's Bug - may require exorcism...
So... I have this script (being called in a perfectly typical way by PHP 4.4.1 through mod_php in Apache 2.0.55) which sometimes runs perfectly, and sometimes chooses, totally haphazardly, to seemingly run itself twice, which of course causes it to die with a fatal error after it tries to redefine some functions. As mysterious as that is, it turns out it must be something altogether more sinister. I tried putting die() at the end of the script, on the assumption that it was for some reason executing twice, yet behold: the problem is still present, and the PHP error log still complains about constants and functions being redefined! The problem, I therefore thought, cannot be that the script is being run twice. (In retrospect, this was the most likely possibility, because the page doesn't actually output anything if it dies with this error.) So for debugging, I added a bit that logs one message to a file immediately before the die() at the end of the file, and a different message after the die(). The die() seems to be working normally, in that it only logs the first message... But wait a second! WTF? If the PHP error log is to be believed, then the script should be dying with a fatal error before it even *gets* to that point in the script, isn't it? And the greater WTF is the fact that, as I mentioned above, every time the page is requested, it unpredictably either does this or works flawlessly. Oh my. How do I even *begin* to debug something like this? Thanks for any help. -- Adam Atlas -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

i agree that in *most* cases destructor should only clean up after object.
unfortunatly for "request" class there are few requirements:
1) must allow immidiate use w/o any explicit initialization or finalizaion.
e.g. at any file You can use only Request::getInstance()->isRefresh() /**
test if this request was caused by browser refresh */. this should be one
and only line (except for inclusion of request.php oc) referencing request
class -- no explicit call to Request::saveToSession() or anything ugly and
potentialy disastrous like that.
2) must provide mechanism for generating per session uniqe request
identiers. now implemented as md5($_SESSION["next_reqest_id"]++) not very
effective but handy:-P
3) must be serializable (this is why i can not put that session manipulation
at __sleep function)
these requirements (1,3) cast out __destruct, __sleep and explicit call to
some saveToSession function. do You have any other idea when to store this
information , please?

Isn't __destruct is called even if reference count is gr then zero as a part
of script finalization? imo yes -- i tried this with echoing something
within singletons destructor (no invoke with explicit delete:-) and it
worked.

*Note* You don't need to use session_register() if you use $_SESSION.
In fact this probably isn't even doing what you think it is. Using
$_SESSION indexes is the preferred way to go about using sessions.

The __destructor() method is supposed to be about killing the class
(Request). It's probably bad practice to be changing $_SESSION vars
inside of there even if that $_SESSION var affects your class. Here,
read this page and maybe it will make more sense to you:

If the reference count for $req is greater than 0 (i.e. there is a
Singleton) then __destruct won't be called. And why should it be
called? Because, again, __destruct is for cleaning up the class while
the object is getting destroyed.

Hallo everybody,

I have troubles with sessions and descructor in php5. Can not set session
variable in destructor when it's called implicitly. Do You know solution
please?
I think problem is that session is stored before imlicit object destruction

unfortunatly this is not set

[PHP] Redirection after login with security
Synopsis: I am writing a management system for a MSSql database driven game, and I've run into an issue. The community site is located on a remote webserver, to protect the actual server from any possible vulnerabilities in the community application/forum application (as we all have seen the recent issues with phpBB and various CMS systems). The management system grants the ability to access and modify various properties of your in-game account. In an attempt to provide the best way to limit the # of accounts per person, I assumed that this could be accomplished by placing a dummy value only used by the site itself that is the username/encoded password for them on the community, and test if... when searched for in the database, a result set of x is discovered, then they are unable to create another account. Problem: I would like to possibly utilize a login system (created on the remote server), that would then check their username and password against the CMS database located there, then redirect with that information (encrypted of course), to the local site where the information gets stored in a session. Then when they go to create a new account, it stores the extra verfied information into the database. However, the issue at hand here is, I'm not sure how secure it would be if I were to say, create a secure login form, verify the data... and then create another pseudo form that directs the person to the local-based site using hidden post variables (this is my original thought on the subject). Is there another way I could go about doing this (ie, a way that I could identify a user that is almost assuredly never going to change) or is there a more secure way? Or, am I on the right track?

The socket_close($sock) is directly after the loop.

Hm. Thats interesting. I attempted that the other day, however at that
time it produced results that are... very similar to an infinite loop
(continuously "loading page" on status bar, and when I hit stop the page
had nothing loaded). I expected it to be the same - however it worked
this time, beautifully in fact.
Thanks, you pushed me to try a second time :P
Thats interesting as well, however... I consulted one of my PHP books
for when I was learning the changes in PHP5 and looked at the example
for socket_connect, it shows an example for querying the Return to
Castle Wolfenstein master server, storing the data in an array, and then
without utilizing socket_close in any of the loops - it continues to
conect to each server and query it for its status (players, settings,
etc). That is why I didnt see much error in my code - the example showed
it to be correct in my eyes.
Anyways, yea, thanks for the help!
($ip was set just above that codeblock, for testing purposes I was using
a local IP - 192.168.1.68 to test for functionality.)

Well, you could use a simple foreach:
foreach ($_POST as $key => $value){
if($value === '') { print("You must fill in all the values");}
else{continue;}
}
I'm not sure if empty($value); would work, but its worth a try.
You could however use it, within the foreach by doing:
empty($_POST[$key]);
(if $key = name, it would test $_POST[$name] whether it is empty or not).
http://us2.php.net/manual/en/function.empty.php
I would assume that empty() would work in this case eitherway, and is
most likely your best bet.
However, within this function it may also be smart to include a few form
validation rules for the security of your form as well.

PHP usually auto-converts data -- However it's possible that this
EXPERIMENTAL function (?) doesn't have the magic code down in the guts of
PHP.
So, try type-casting your third parameter to an (int):
$currport = $servers[$key]['Port']; // was attempting this to see
$currport = (int) $servers[$key]['Port'];
echo "currport is: '$currport'\n";
If this fixes it, file a bug report at http://bugs.php.net -- search for
the same issue first. It should get fixed pretty quick-like (relatively
speaking) if that's all it is.
It's also possible that your 'Port' is empty or something... That's why I
included the 'echo' -- Always hand-check the data you are sending when
weird things happen.
One line of debugging output can save hours of time and fistfuls of hair.
I actually fixed it by using a simple preg_replace to remove any
returns/spaces. It was actually imported from a text file and I forgot
to clean up any excess characters taht could still exist.

Warning: socket_connect() expects parameter 3 to be long, string given

Couldn't Create Socket: Success
It actually spits that across for every socket I'm trying to connect.
I'm doing an online status for multiple servers, which I have tested to
work when I simply do a socket_connect($sock,$url,$port); on the port
numbers of the various servers. The servers all reside on the same IP
address.
The script actually works manually, ie if i put the actual port in to
the socket_connect function call. However, as soon as I put the variable
in - it wont work.
The code looks like so:
foreach ($servers as $key => $value){
$currport = $servers[$key]['Port']; // was attempting this to see
if it would work - it did not either. Normally tried
$servers[$key]['Port'] directly.
if(!socket_connect($sock, $ip, $currport)){

}
else{

}
}
I cant quite find anything that is... actually wrong with the code. I
dont understand the error all that much either, as it says "Success" in
it. Needless to say - I'm thoroughly confused!

[PHP] Preventing execution without inclusion
From within the application, I use one page to include
classes/variables and so on. Is there a way (I may have been missing it
in the documentation for PHP, however I didnt see anything related) to
prevent a user from directly accessing/executing *.php by the file
making sure taht it was only included by index.php?
For example:
config.php defines:
function __autoload($class_name) {
$class_name = strtolower($class_name);
include_once('class.'.$class_name.'.php');
}
as per PHP5 example
1 (the preferred way): user accesses
http://www.example.org/index.php?function=Join, this loads the class
NewUser and begins its implementation. Because of the __autoload, it
includes class.join.php, in order to utilize the class.
2 (the wrong way): user accesses
http://www.example.org/includes/class.join.php without going through
index.php.
I am trying to prevent 2 from even occuring, utilizing a piece of code
that would check if index.php had included it, or not. This code would
be in the beginning of all the class files, at the top, before any other

[PHP] Good Class/API Design ?
Hey all, I just got my hands on the excellent books PHP Anthology 1 & 2 and am wanting to start playing around with classes. My question to the list is, what, in your opinion, constitutes good class/api design? Is it better to design several smaller classes that each focus on one task and do that task well, or to build more general classes that handle a number of related tasks? Also, when you are beginning a new project, what methods do you find helpful to follow in taking your project from concept to finished? The books also mention ways to use phpDocumentor to document your code and SimpleTest to test your code as it is written. These along with some XP techniques I read about seem like good practices to follow. Does anyone have any other ideas/practices that it would be good for a new oop developer like myself to make a habit it of?

So now it works except on the very last line it processes, it prints "does not exist", so there is still some sort of a hidden character but its not affecting fetching the URLs from the web server. so i'm still trying to figure that last line out, but everything else works. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] fopen and http://
Hi, I'm having a problem with fopen and http files. I keep getting the
error:
Warning: fopen(http://zed/htdocs/rgfindingaids/series594.html )
[function.fopen]: failed to open stream: HTTP request failed! HTTP/1.1 404
Not Found in /home/awilliam/public_html/rgfaidstest.php on line 15
http://zed/htdocs/rgfindingaids/series594.html does not exist

Not Found in /home/awilliam/public_html/rgfaidstest.php on line 15
http://zed/htdocs/rgfindingaids/ser392.html does not exist
I have a text file /home/awilliam/public_html/rgfaids containing URLs such
as:
http://zed/htdocs/rgfindingaids/series594.html
http://zed/htdocs/rgfindingaids/ser391.html
http://zed/htdocs/rgfindingaids/ser392.html
and I can bring up these URLs fine in a browser on the PC i'm running the
script on.
The following is my code:
";
}
elseif ($filetotest)
{
echo "$line does exist";
}
}
?>
But I don't understand why I am getting that error about failed to open
strem: HTTP request failed, when I can bring up the links fine in a
browser on the server running the php script. So can anyone help me out?
Thanks

[PHP] opposite of array_unique()?
array_unique() removes duplicate values from an array. Is there an opposite function or way of keeping all values in a single dimentional array that are duplicates and removing all that are duplicates? for example if I have an array: array( [0] => 'dog', [1] => 'cat', [2] => 'rabbit', [3] => 'cat') how do I make it just have array ( [0] => 'cat' )? i want to drop the non-duplicates and trim the array to only have one of the duplicates? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
