[PHP] Problem with PHP5, CGI and Session

[Markus Fischer]

Hi,
I'm expiriencing a problem when I use my application with PHP5 as a CGI module 
(this is due to my provider). I've developed and tested the application on two 
servers, both using PHP5 as module, without problems.
It seems that the session gets malformed somehow during the first reuqest.
1) On the first request, the session itself is empty:
array(0) { }
2) On the second request, using session cookies, I see the initialized session 
array:
array(1) { ["fru"]=>  &array(1) { ["cache"]=>  array(0) { } } }
But only as long as I'm in my applications constructor.
But as soon as my class' constructor returns, the session suddenly contains 
another value:
object(Application)#1 (4) {
 ["db:protected"]=>
 object(TsMySQLConnection)#2 (4) {
   ["conRes:private"]=>
[..]
The simplified code-flow is:
session.php
class MySession {
function __construct() {
session_start();
$_SESSION['app']['cache'] = array();
}
}
application.php
class Application {
protected $session;
function __construct() {
$this->session = new MySession();
}
}
index.php
require_once 'application.php';
$app = new Application;
# here, var_dump($_SESSION['fru']) outputs suddenly the 
Application-class, instead of the empty array
$app->main();
I'm unable to find out the problem. It seems that after return from the 
constructor the _SESSION is messed up and contains the object which I just 
created newly.
Anyone expiriencing similiar problems?
regards,
- Markus

[PHP] register_user_func and register_shutdown_func

[Bostjan Skufca @ domenca.com]

Hi all,

is there any internal difference between following calls (they occur inside 
some class)?

#1 register_shutdown_function(array($this, 'myfunc'));
#2 register_shutdown_function(array(&$this, 'myfunc'));
(note the reference operator in #2)

Or is parameter "$this" in example #1 forced to be taken as reference 
internally, which makes both calls basically identical?


Thank you for your kind response.


Best regards,
Bostjan Skufca

Re: [PHP] getting name of class from a parent

[Chris]

I'm not sure I'm quite clear on what you want, ...

class base_class{
  static function get_instance(){
   static $oUtility = new utility_class();
   return $oUtility;
   }
}
class utility_class {
}
$instance = utility_class::get_instance()
?>
That should create an instance of utility_class the first time 
::get_instance() is called, and just return it afterwards. I'm not 
positive it will work, the relationship between the two objects, with 
the parent instantiating it's own child, is quite complex.

Hope this was of some help.

You may be wondering why I don't just " $instance = new utility_class 
" - the reason is that I want to only create one of these instances. I
don't want any more than one instance of utility_class at any one
time.

I can't use get_class($this) either, because, there is no $this when
I'm accessing the method staticly.
Any suggestions?

[PHP] Output buffering - saving + echoing

[Lorderon]

Hi,

When using ob_start(), the output is buffered and not sent till
ob_end_flush() is called or got to end of the script. Also before flushing
you can get the buffer contents by ob_get_contents().



What I want to do is "catch" the output buffer, but do not delay the buffer
to be sent. How is it done?


thanks in advance,
Lorderon.

Re: [PHP] getting a date 25 years back

You should do date arithmetic using the Unix date format (number of 
seconds since 1970).
I think these string format dates are not appropriate.

[PHP] Google search indexing

It doesn't. It indexes the HTML that they output. As far as Google is

See, you knew this anyway ;)
sp> Do other search engine use different methodologies?
Thankfully not - if they could it would mean they could see into our
PHP code and MySQL databases.
This is really two questions about Google indexing
Let's say I have a site in PHP & MySQL.
Let's say that I have some links on my site that use GET variables to 
call other PHP pages and pass them a GET variable, like

http://www.somesite.com/somedir/somepage.php?flag=15
The "flag" variable is passed to somepage.php and read by the script 
using $_GET['flag'] etc, etc. When you look at the page with flag=15, 
you get one page, when you look at it with flag=14 you see a similar 
page with completely different content (record #14 instead of #15 
obviously)

Will Google see both pages if I have both linked with  
tags? Or will it stop at the question mark, only loading the page 
somepage.php and ignore the ?flag=14 and ?flag=15 or whatever? Will 
it index ?flag=14 and ?flag=15 as two separate pages (which is really 
what I want, since they produce different content), or will it treat 
both as the same page?

SECOND QUESTION, RELATED:
Same scenario, but with a POSTed form. I have several hidden FORM 
fields, an a drop-down, and depending on how you submit the form you 
get different content on the resulting page.

Will Google submit the form, perhaps a couple of different ways and 
treat each resulting page differently, or will it just bypass the 
form altogether?

THIRD QUESTION:
If the answers to the questions above are Yes and No, then I could 
use a dynamically generated list of links with ?flag= to make Google 
crawl through the part of the MySQL content (as displayed through the 
scripts in HTML) that I want it to, using links and GET variables, 
right?

If the answers to the questions above are No and No, do I have to set 
up a static .php page for EVERY record in my MySQL database to make 
it see that content I want it to see? Does anyone use the error.php 
page to catch for a 404 Not Found error, see if it can match the 
"ghost" name to a record in the DB, and display a page anyway (even 
though technically there is no somepage.php page, the error.php page 
knows to go look in the databsae for "somepage" and displays its 
content)?  I wonder if this would be a good optimization strategy.

(Of course, some of my MySQL dbs I want it to see and others I dont)
Thanks in advance.

[PHP] Re: Getting mail() to return false/0

[Manuel Lemos]

Hello,
Paul Reinheimer said the following on 12/14/2004 11:49 PM:
I read that as, mail() will return true if PHP is able to connect to
the MTA, pass the message, and the MTA responds that the message was
accepted.
My understanding (or assumption) of how the MTA operates is that it
would not accept a message it did not know how to deliver, ie one with
an invalid destination address.
That being said, there is an article on builder.com with regards to
mail and PHP which states:
The mail() function will return true as long as it connects to the
specified SMTP server. This does not mean that the mail successfully
reached its intended recipient. The mail() function does not wait for
or report success/error codes from the SMTP server
This is not true under Unix/Linux as PHP does not establish an SMTP 
connection. It only pipes the message to the sendmail program (or an 
emulation). Sendmail may even try to deliver the message immediately but 
if it fails it may retry later or the message bounces to the return 
address, but the mail() function still returns true.

The mail function only returns false under Windows when the SMTP server 
does not accept the message for relay for a variety of possible reasons. 
Once the message is accepted for relay, even if the recipient address is 
invalid, the message may end up bouncing later, but the mail function 
still returns true.

'dude' is in fact not a user on my box, I was in fact something I
choose trying to use as an example of something that was not valid.
Running it again against "asdadasdsadasdadsad" returns the same
result.

When I do send mail that matters I include a From header, I was just
trying to stick with as simple an example of what I expected not to
work as possible.

Ramil: I am surprised to hear that, as it directly contridicts what is

In the continuing trend of responding to my own messages Perhapps
the issue is with how I am interpreting the docs, which state:
mail() returns TRUE if the mail was successfully accepted for

I read that as, mail() will return true if PHP is able to connect to
the MTA, pass the message, and the MTA responds that the message was
accepted.

Damn.

Okay, maybe maybe maybe try putting your binary data into a temp file, and
then sending that file out.

It won't be fast, but it might suffice for what you need.

That's assuming fwrite() to a file will output binary data...

Another option would be to convert to the string that would match the
binary data you want...

if (is_int($msg_to_send)){
  fwrite($fp, chr($msg_to_send));
}
else{
  fwrite($fp, $msg_to_send);
}

This would be faster, and probably cleaner than the temp file, actually.

NOTE: is_int is faster than gettype() == 'integer' and the manual states
that they don't guarantee that 'integer' won't change some day.  Use
is_int.

You can use mktime() and subtract 25 from the year argument.
Or just do it in your query...

If $connection is an invalid link, it most certainly does print an error
message.

I apologize for leaving out the $connection argument, however.

The correct code is:

$connection = @mysql_connect('localhost', 'USERNAME', 'PASSWORD') or 
trigger_error(@mysql_error($connection) . " connecting to mysql",
E_USER_ERROR);

It's Bad Programming to rely on the default argument.  I spent a *WEEK*
tracking down a case where the "Programmer" was connection to a different
database (he thought) and closing it, only he was closing his main
connection.  But only sometimes, because he only called the sub-routine
sometimes.  Aggh.

[NOTE]
In very old versions of PHP, mysql_error() would not have the error
message in the event of a failed connection -- You'd have to check PHP's
internal error message variables/functions if you run this on really old
PHP versions.
[/NOTE]

>> @mysql_select_db('DATABASENAME', $connection) or
>> trigger_error(@mysql_error($connection) . " selecting database",

Once again, if $connection is an invalid resource, it will.

So if you manage to get a good connection in the mysql_connect() line
above, and MySQL *dies* on your server before you get to this line of
code, then you have a potential error condition that will trigger this.

That may not happen very often -- In fact, odds are it will happen very
RARELY.  But it *can* happen, and not coding for it is Bad Programming.

I can guarantee this can happen, because it *has* happened to me.  Once.

Repeat comments from above.

I guess you've never had your database connection die on you in the middle
of processing, eh?

Well, it *does* happen, occasionally.

Program for it.

Also, I come from a PostgreSQL background, where PHP generates a message
on the attempt to read past the last row (which ends the loop) so I'm in
the habit of using @ there anyway.

[NOTE]
It may be that case that PostgreSQL/PHP only generates a NOTICE level
message which you only see if you have error_reporting() cranked up to
E_ALL level.  If you don't see the notice message, don't tell me I'm
wrong. Re-set your http://php.net/error_reporting and test again.
[/NOTE]

Even if I were solely a MySQL user, the database *CAN* go down in mid-loop.

Read more carefully :-)

See all the http://php.net/trigger_error calls?

I'm actually setting the Reader up to have *BETTER* error handling than
the ubiquitous (and horrible) "or die()" construct.

Using trigger_error consistently allows one to use:
http://php.net/set_error_handler
some day, and do something useful, maybe even intelligent, with the error
handling.

Meanwhile, the @ suppresses the default PHP error message, but
trigger_error spews out a more complete error message, resulting in about
the same quality of debugging as "or die()"

It just gives one flexibility for tomorrow to do something smart when one
realizes how bad "or die()" is. :-)

I don't know how many million scripters are using "or die()" because they
think it's the Right Thing because it's in every example in the on-line
manual, and every post, and every on-line tutorial, except for the
occasional good tutorial about error-handling itself.

It's no tougher to use trigger_error() without an error handler than
die(), and at least maybe someday they'll be able to convert their scripts
to use a real error-handler.

So, bottom line:  If you want to write sloppy code and not check for
possible error conditions, go right ahead. :-)

But don't be chastising me for writing GOOD code! :-) :-) :-)

If Google (et al) see the pages AT ALL, they will see them as separate
pages.  They have different URLs <==> they are different pages

Some search engines skip all URLs with ? in them.

Others selectively use the URLs with ? in them.

It's possible (but unlikely) that some search engines use *all* the URLs
with ? in them.

I don't know what Google, specifically, will do under what circumstances,
much less what they might decide to do tomorrow or next year.

I don't know of *ANY* search engine that will POST data to get to content.

I sincerely doubt they would want to do that, really.

Maybe.

Google might do it, while others won't and vice versa.

There are several other possible solutions:
1. Use your robots.txt file to send the search engines to a "secret" page
that links to all your content, asking the engine to index that page.

2. Use Apache's mod_rewrite module to change URLs like:
http://example.com/page.php?flag=14
to URLs like:
http://example.com/page.php/flag/14
or
http://example.com/page.php/flag=14
or
http://exmaple.com/page/flag=14/page.htm

3. Use PHP and $_SERVER['PATH_INFO'] to do all the same things as in #2.
There are many examples/articles "out there" how to do this.
Google for "PHP $_SERVER PATH_INFO" and you should find some.

Also be sure to Google for "robots.txt search engines" to find out more
about the robots.txt file -- While I don't use it much myself, others find
it useful.

Finally, a note of caution.  At some point, if you have *enough* records,
you don't want to make the URLs look static.  If you do, and force Google
(et al) to index, say, a MILLION relatively un-interesting pages...

Put yourself in Google's shoes:  "Hey, here's this goofball that made us
index 1,000,000 pages of uninteresting content.  Let's just put him on the
blacklist and not index his site at all."

Use some common sense here, or suffer the consequences.

Let me give you an example:

Suppose you were responsible for maintaining a list of, oh, I don't know,
registered Republicans/Democrats.  Further suppose, for some reason, that
making this list public on the web was legal (I dunno) and you wanted to,
or, more likely, your boss wanted you to do that.

You *could* have a site where every registered voter was on their own page
with an elephant or donkey, and you *could* make static-looking URLs to
force them to get Googled...

Or you could have static-looking *pages* so every page has a couple
hundred, or even a thousand peope, to get Googled, with a nice common
masthead with the elephant or donkey.

If you force the search engines to index those zillion pages, one for each
person, you're going to make somebody cranky.  Somebody you *want* to be
friends with.

OTOH, if you arrange it so they aren't indexing *too* many pages, and the
content is useful to pot

Re: [PHP] Google search indexing

[Merlin]

You could also use a file called for example "pictures"
parse this file with php (use an apache directive for that)
and add the filename. Then you can get the filename from the url and interprete 
it inside the php file "pictures".

Its funny what you can do with php, and nobody will notice, not even the 
spiders.

[PHP] finding out the age from a birthdate

[Merlin]

Hi there,
i am somehow strugling to find out how to get the age of a person from its 
birthdate. If I divide the date from today, there still is a year instead of the 
age. And deviding the years does not work since we should be accurat about the day.

I tried:
$age[] = date("Y",(time()-$birthday));
(where birthday is a unix timestamp)
Has anybody an idea how to do that?

I assume you have placed the MySQL query and checked the number of

while ($row == mysql_fetch_assoc($result))
{
  $name = $row['name'];
  $desc = $row['description'];
  echo "$name ";

}
and you're not just doing

yes it works, but is it useful?
This is just one of many ways of performing the same task. You could
use a for() loop based on mysql_num_rows, you could use fetch_array
instead of assoc. If you are only extracting a couple of details then
you could even use mysql_result($result, $record, 'name'). I would
suggest you take a look in the PHP manual, there are many examples of
this.

[PHP] CGI vs Apache module

[Sandy Keathley]

We have a Redhat server, which only allows PHP 4.3.2 to be 
installed by RPM.  I manually compiled and installed 4.3.9 using 
the configure params as the RPM install.  It compiled the CGI 
version, which seems to run, but Apache (2.0) doesn't recognize it.
phpinfo() still reports 4.3.2.

Any ideas accepted on making 4.3.9 the default version!

Thanks,

A quick google would have answered your question! Just have a look at some 
typical search results and you'll see that Google will index those dynamic 
pages.http://www.metasystema.org/essays/reply-to-useful.mhtml

AFAIK search engines don't submit forms. It would be extremely impolite to do 
so. Imagine a form for comments and Google "enters" some rubbish and submits 
it.

Are we still talking about search engines? Strictly speaking no search engine 
(crawler to be precise) should ever try to access a non-existent page. If you 
have moved pages around and want a search engine to still be able to access 
the now non-existent page then you should issue the correct HTTP header code 
for "resource moved permanently" (or whatever) and redirect to the new page.

Re: [PHP] fopen/fpassthur

[Sebastian]

Q> I hope you have some good data validation going on too :)

I am not too sure about how secure it is. basically, the files are called by
an ID
eg, download?type=file&id=3

so i query the db to get check if its a valid id and get the filename from
the db as well.
if its not found it errors out.. i was under the impression that is more
secure to get files by an id from db than doing something like
download?file=filename.zip

i am worried about security as i am not even sure if this method would allow
people to download any file from the server.
maybe if you have time you can look at the script for me and find any flaws
;)

[PHP] getting name of class from a parent

[Rory Browne]

Hi

I need a way to create an instance of a class, from a parent of that class.

Lets say I have the following code:



You may be wondering why I don't just " $instance = new utility_class 
" - the reason is that I want to only create one of these instances. I
don't want any more than one instance of utility_class at any one
time.

I can't use get_class($this) either, because, there is no $this when
I'm accessing the method staticly.

Any suggestions?

Re: [PHP] PHP cross platform IDE

[Rory Browne]

I use kdevelop. I'm not sure how cross-platform it is, since I've
never tried to get it working on a non-linux machine, but it should
run anywhere KDE will run. I'm not sure what you'd need to do to get
it running on Windows.

Vim is a text editor, albeit a very good one, but Not an IDE, even
though it has many IDE features.

I haven't used the Eclipse plugin yet. What's it like?

[PHP] Getting mail() to return false/0

[Paul Reinheimer]

Hi,

I was working with the mail function today to experiment with sending
a few messages, and threw in the apropriate checks so when mail()
can't send the message the apropriate errors were raised, however, I
discovered I couldn't actually get mail() to return 0. Take the
following call:
mail("dude", "Daily Feed Update", "body");

When I run that exact call (well, I prepend echo, but you get the
idea) it returns 1. I can't for the life of me understand why my MTA
would accept an email with a destination of 'dude'.

Any thoughts?

while you're gone (you won't miss much, trust me) or 2) set your notice 
to not reply to postings to the list. These get quite annoying after a 
while, if you can imagine. Yes, I know how to filter them to my Junk

Use:

#!/usr/bin/php -qC

The C flag makes it the working directory for the script the same one as
your are in when you invoke it. Also ensure that your PHP binary exists
at the specified path. Last but not least you still need the opening PHP

It's not at all difficult.  The definition of fwrite is:

  int fwrite (resource handle, string string [, int length])

So the second parameter is converted to a string as it passes in to fwrite.
This is not at all unexpected -- it's kind of the file(/stream/whatever)
analogue of echo or print.

To get what you really want -- i.e. a 1-byte binary representation of your
value -- you'll have to encode it as the appropriate character and then send
that.  Two possible ways to do that are with pack() and chr().

Cheers!

If you can access that mailbox via POP3, you can try using this POP3

Unless you actually *WANT* PHP as CGI, go back and re-compile as Module.

Right before you do "make install" you'll need to RPM un-install PHP, so
you don't confuse things.

You'll need to re-start Apache for sure, and if that doesn't work, you may
need to change the httpd.conf settings by hand.

I don't know where RPM-makers hide your httpd.conf file, but you should be
able to find it and edit it to find the PHP parts and fix them up.

Re: [PHP] Google search indexing

[Richard Lynch]

> I've heard different claims about how google handles GET queries and am
> pretty sure it doesn't submit POSTed forms.

I can guarantee that at least one time one search engine indexed a URL
with GET data in it.

Shocked the [bleep] out of me to find one of my dynamic pages in a search
results page. :-)  "Hey!  They don't index those dynamix pages?!  Hmmm. 
Guess they do now.  Sometimes."

I don't know what sort of algorithm the search engines use to decide
which, if any, URLs with ? in them are worth indexing or not.

Since Google won't publish their inner workings, one can only hypothesize
and theorize about what they do.

But once I found that one URL, I decided to re-think a lot of my sites and
now I make the decision on a page by page basis if I want a static-looking
URL or a dynamic-looking one.

I'd much rather do that than try to beat my head against the "How does
Google work" wall, or wade through a zillion "search engine optimization"
experts' postings (much of which is bunk or out-dated or sheer
guess-work).

Maybe someday search engines will make an informed decision that even a
static-looking URL is really dynamic, and classify it in the "don't index"
bucket, and vice versa.

For the forseeable future, though, I think it's safe to say that rewriting
your URLs will help search engines find you.

Worked for me.  A musical artist I know (and you almost-for-sure don't
know of him) checks his own name Google et al routinely every few weeks or
so.  He's quite disconcerted when one of my pages "bumps" his own site
down to #2 occasionally.  Fortunately, he usually pops back up to #1 next
time he tests.

Thank goodness we're friends and he controls the content on his profile on
my site, so it's always up to him what people see when they go there
anyway.

In terms of bang for the buck in search engine optimization, making your
URLs search-engine friendly has to be just about as good as it gets.

If *NOT*, then you really don't need all the nested categories in your

Of course, you could simply walk through $_SERVER['PATH_INFO'] and

You can do this in all MySQL:

Or you could try:
$back_then = mktime(0, 0, 0, date('m'), date('d'), date('Y') - 25);

If you mean any of the potential downloads, you've got big problems. :-)

What's to stop somebody from trying &id=4 and &id=5 and so on and getting
*ALL* the files?

If you mean they could download *any* file, even the ones you're not
trying to let somebody download, it would be more efficient to see the
script itself to point out flaws, rather than just surfing to the site and
trying to break it.  Though that can be instructive too, especially if you
have acquired the same sort of tools your average script kiddie uses to
try to break in and steal stuff.

On a very gross simplified level, the Zend optimizer works like this:

When the user requests "*.php" URL:
1  Check if the page is in the cache.
2  Load the PHP script from the disk.
3  Compile the PHP script to byte-code.
4  Check for ~20 specific optimizations to alter the compilation
5  Store the byte-code in a list matching URL <-> byte-code.
6  Execute the byte-code script.

The next time that URL is requested, steps 2, 3, 4, and 5 are *skipped*

It simply finds the byte-code in RAM and starts executing it.  Pretty much
like a big fat "GOTO" to skip all those slow steps :-)

Step 2 is the BIG win, actually.  Hard drive slow.  RAM fast.

Step 3, compiling PHP to byte-code saves a bit of time to skip, but not a
whole whole lot usually.

Step 4 you have control over which Optimizations it does or skips.  The
default settings, which is probably not even to have all 20 Optimizations
"on" usually works best for the "average" user, whatever that means.

If the Zend Optimizer actually made your site slower, then...

Perhaps you tried to set the memory size for the Optimizer really high,
and you are page-faulting the cache back onto the disk.  Don't do that.
:-)  Set your Zend memory size to something that will actually fit in RAM.
 More RAM + the Zend Optimizer can also make a *huge* difference if you
were bordering on RAM full before.

It's also possible that your scripts are triggering some particular
condition among the ~20 optimizations.  You can try turning them on/off
one by one or in a binary search to see if it's a particular optimization.
 You do this in the Zend config file.  It will take some time and effort
to tweak and test, but it may turn out that the default settings suck for
you for some odd reason, even though they're great for 99% of the users. 
That's why they let you change them :-)

Actually, maybe start by turning off *all* Optimizations and re-testing. 
Right there you can determine if it's an Optimization or a RAM issue.

The Zend Optimizer also comes with (or used to anyway) a feature to track
the performance/pages that came out of the cache and generated some simple
statistics from that to give you some idea what it was doing.

Disclosure/Disclaimer:  I used to work for Zend as "Vice President of
Customer Support" answering questions like this.  In no way, shape, or
form, does that make this answer official, correct, or authoritative. :-)
YMMV. NAIAA. IANAL.

PS  The Zend Optimizer is actually way way way more complicated than this
brief description, but that's the way life goes, ya know?

I am not too sure about how secure it is. basically, the files are called by
an ID
eg, download?type=file&id=3
so i query the db to get check if its a valid id and get the filename from
the db as well.
if its not found it errors out.. i was under the impression that is more
secure to get files by an id from db than doing something like
download?file=filename.zip
i am worried about security as i am not even sure if this method would allow
people to download any file from the server.
maybe if you have time you can look at the script for me and find any flaws
While this method may not present a clear security danger, how does the 
data get into the database? If I can feed a "filename" of anything on 
your system that you blindly put in the database, then I can call it 
with an appropriate URL.

So... you can trust data coming from your database only if it was 
trusted/validated/sanitized going in. :)

There was a bug in PHP for a very brief period of time where scripts were
not ending under some conditions after all the content was delivered.

If one is running that version of PHP, exit; at the end of a script is a
Good Thing.

Comment out the header("Content-type: ...") line in your script.

Then surf directly to the image:
http://example.com/bargraph.php

You should then be able to read the error messages PHP is probably
printing instead of an image.

The browser isn't smart enough to tell that that PHP error message isn't
supposed to be an image at all, and tries to interpret it as an image. 
Oddly enough, it never quite works, eh? :-)

You re-started Apache, right?...

Just to be sure, does  show 'test1' as the user?

If so, check http://bugs.php.net for your OS/PHP version and bugs related
to file upload:  If the user running PHP can do all that stuff, PHP should
be able to do it with no problem.

[PHP] Loops

[Steve Marquez]

Greetings. I am trying to display looped information from a MySQL database
in a PHP file. 

Loop

$name (witht a br />) then
$description

End of loop

I would like to loop the multiple variables rather than put all the
variables into a single variable with an array. I can not figure out how to
do this.

I have very little knowledge of PHP but am learning. Let me know if more
information is needed.

Thank you for any help.

I've heard different claims about how google handles GET queries and am

There are, however, other options than simply setting up static pages

It seems more likely to me that fgets() is timing out.

You may need to resort to lower-level function calls to keep the stream open.

Check for PHP functions that change the time-out limit of streams and
sockets here:

[PHP] Slow Zend Optimizer

[Bruno B B Magalhães]

Hi guys,
I've installed the zend Optimizer with my Mac OS X, Apache 1.2, PHP5. 
And guess what, it became about 40% slower!!!

My framework was running for example in the modules administration 
(admin area) at 0.104ms, and now the average is 0.2ms - 0.24ms

Does anybody have any idea of what hell is this optimizer optimizing?!?1

Thanks Richard.

I thought of that too and have since expanded my debugging. The types
are correct when passed to fwrite. They come out the other end as
strings:

16:39:54 SENT 'K' of type string
16:39:54 SENT '0' of type integer
16:39:54 SENT '0' of type integer
16:39:54 SENT '65' of type integer
16:39:54 SENT '31' of type integer

15:46:10  192.168.0.101:32778 --> 192.168.0.84:32896 | UDP |

 : 4b   K


15:46:10  192.168.0.101:32778 --> 192.168.0.84:32896 | UDP |


 : 30   0


15:46:10  192.168.0.101:32778 --> 192.168.0.84:32896 | UDP |

 : 30   0


15:46:10  192.168.0.101:32778 --> 192.168.0.84:32896 | UDP |

 : 3635 65


15:46:10  192.168.0.101:32778 --> 192.168.0.84:32896 | UDP |

 : 3331 31

As you can see, the last two elements "65" and "31" have arrived as
strings of two bytes rather than integers of one.

Not to be rude, but adding so many @s is usually considered bad

I use something almost identical, except I upper-case the second words

I'd fclose() when done, and no need to exit() - it's the last line of

I hope you have some good data validation going on too :)

It is the way to do it, yes. You may get some varying suggestions re:

No, you cannot interrupt the stream. Or do anything after it for that
matter - you are "simulating" an HTTP request for a file, that is what
you're sending back. There is no way to inject something else into
this single transmission. Think of another way around it.

Probably.

http://php.net/zlib should give you some ideas in that direction.

It would maybe be easier to start with all unzipped files, and zip them
with your text file when you send them out...

I assume you have placed the MySQL query and checked the number of
rows it has returned? You could just do:

while ($row == mysql_fetch_assoc($result))
{
  $name = $row['name'];
  $desc = $row['description'];

  echo "$name ";
  echo "desc ";
}

This is just one of many ways of performing the same task. You could
use a for() loop based on mysql_num_rows, you could use fetch_array
instead of assoc. If you are only extracting a couple of details then
you could even use mysql_result($result, $record, 'name'). I would
suggest you take a look in the PHP manual, there are many examples of
this.

http://phpclasses.org might have one.

You'll want to look into 'smrsh' and some sendmail documentation for how
to get the email to the PHP script in the first place, if you want this to
happen the instant the email comes in.

If you can wait a minute or two longer per email, you can use
http://php.net/imap to open up and read email and then process them as you
see fit.

Not sure what you mean by using SSL with PHP...

There's really not a whole lot to it.

You put SSL on your server, and PHP on your server, and, like, they both
work. :-)

When switching from your non-SSL pages to SSL pages and back, you have to
transfer any "context" (session, GET/POST variables, etc) back and forth.

Just general advice:  Keep your SSL pages in a well-defined and clear-cut
place in your application, as much as possible, if you mix non-SSL and SSL
pages.

If you want to use PHP to read from SSL sites, go here: http://php.net/curl

I suspect that PHP is converting your integers into strings at some point,
as you build the array...

*WHERE* it is doing that is difficult to say, without seeing more code.

It doesn't. It indexes the HTML that they output. As far as Google is

[PHP] fopen/fpassthur

[Sebastian]

Hi all,
I have created a download manger to handle files, when a user clicks a link
the file is sent though fopen() and fpassthru()
like this:

header("Content-type: application/octet-stream");
header("Content-disposition: attachment; filename=" . $file['filename']);
header("Content-transfer-encoding: binary");
header("Content-length: " . filesize($file['path'] . $file['filename']));

// get file contents
$file = @fopen($file['path'] . $file['filename'], 'r');

// output
fpassthru($file);
exit;

is this the most practical way of doing it? i don't want to display file
location.. the script seems to be working okay, but i was just looking for
opinions on the method. also, is it possible to insert a txt file on the fly
if the file they're downloading is a ZIP file? if so, any ideas how?

echo "{$row['name']}$row['description']";

I would like to loop the multiple variables rather than put all the
variables into a single variable with an array. I can not figure out 
how to
do this.

I have very little knowledge of PHP but am learning. Let me know if 
more
information is needed.

Thank you for any help.

[PHP] PHP cross platform IDE

[Bryan Dina]

I have done a little checking and I think I already know the answer, but
I wanted to toss this one out there anyway.

Are there any cross platform IDE's available for PHP v.5 development,
specifically I am looking for Linux/Mac.

A bit off topic, what are people out there using for PHP IDE's?

thanks!

Thought not specifically a PHP IDE, I use Visual Slick Edit (which
is cross platform).  It's probably the best IDE I've come across to
date.

thnx,

but in my application server, I got this â?T&*%$ in my mysql server (i.e. '
==> â?T)

anyone know how to resolve this? When I use the string to send out the
email, I got the funny characters instead.

Version Running

development server
mysql-server-3.23.58-9
php-4.3.4

application server:
mysql-server-3.23.58-9
php-4.3.8-2.1

[PHP] Good and free encoder for PHP5

[Mário Gamito]

Hi,
Does anyone around here knows a *good* and *free* encoder for PHP5 ?
I used to run Turck, but it seems that somehow it has been discontinued.
(At least, the last release occured about a year ago).
Any help would be apreciated.
Warm Regards.
