Re: [PHP] URL restriction on XML file
That's because the character data is split on the borders of the

The output for line 1 is truncated to 'f=1' and the output of line 3 is
truncated to 'cat=somecat'. ie, the script only took the last parameter of the
url-link. The output for line 2 is correct since it has NO parameters.

Is there a so sort of a problem here that I am not thinking of? I only can imagine problem that the rand() gives the same value twice. But I cant see this as a major problem because there would be maybe not more than 1000 uploaded pictures. So the chance is at worst something like 1:10 000 that same name is created to the image.

I tested Richards reproduce script on php 5.0.3 on a Debian

register_globals = Off
register_long_arrays = Off
register_argc_argv = Off
magic_quotes_gpc = Off
magic_quotes_runtime = Off
(i.e. all relevant ini settings are php5 defaults)
and I get the same freakin' references from/in the SESSION array.
Actually, they *ARE* enabled by my webhost.
I don't really think that's relevant, however, as PHP is storing $name
back *IN* to my $_SESSION data, just because I did:
$name = $_SESSION['name'];
$name = Fooey;
$name is a STRING.
It's not an object.
It should *NOT* be a Reference!
But it is a Reference, so changing $name alters $_SESSION['name']
Sorry, meant to reply to list, not just you.
All I'm saying is that Sessions act extremely oddly with
register_globals enabled.
With register_globals on I believe the global variable, acts as a
reference. It's not because it's a string, it's because it's a session
variable, and it needs to keep track of changes to the variable.
I agree with Chris that register_globals can only cause more pain and
misery :-/
but in this case the problem exists regardless of register_globals setting.
here is a func I sometimes use when going to war with a register_globals=On

nothing special and I blagged the idea from somewhere/someone (probably in the
user comments somewhere in the php manual :-/)
function unRegisterGlobals()
{
if (ini_get('register_globals')) {
$SGs = array($_SERVER, $_ENV, $_FILES, $_COOKIE, $_POST, $_GET);

Re: [PHP] RE: Best Server OS
I've used Macs for a long time and think it's a great client and OS. The GUI stuff they have for the server I think is great too. But when considering the best OS for a server, I would hardly recommend it, except from an ease of use and setup standpoint. Apple is still coming up to speed on all the underpinnings, partly because of the changes BSD is going through (i.e. changing the threading model). Tiger I think will be a big boost and the planned eventual transition to gcc 4 will be an even bigger boost. I read an article recently that compared MySQL and other software performance on various operating systems, including Windows, Solaris, FreeBSD, OpenBSD, NetBSD and Linux (gentoo). Linux pretty much stole the show, mainly because of it's threading design. Using Linux threads on BSD improved performance on BSD systems. While OSX wasn't tested, you could extrapolate where it might fall in the review since it is based on BSD. http://software.newsforge.com/article.pl?sid=04/12/27/1243207from=rss On Mar 29, 2005, at 11:10 AM, Gerald Artman wrote: I would recommend OSX Top ratings on security compared to Linux or Windows Fast processors in many configurations, most include 1000T Starting at $500 to $3500 for up to +15MIPS performance Excellent GUI interface Supported by Apache, PHP, MySQL and comes pre-installed Jerry Artman -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- Brent Baisley Systems Architect Landover Associates, Inc.

Give your cookie an expire time in the past
setcookie ( $name, , time() - 3600 );
If you don't give it a time, it will be a 'session' cookie, and will

RE: [PHP] asking comment
I got a bit frustrated with image upload stuff with different
image name problems. So I created a system that gives the
uploaded imaged a random numeric name between 1-10 000 000
and saves the file to a server folder and the image name to mysql DB.
Is there a so sort of a problem here that I am not thinking
of? I only can imagine problem that the rand() gives the same
value twice. But I cant see this as a major problem because
there would be maybe not more than 1000 uploaded pictures. So
the chance is at worst something like 1:10 000 that same name
is created to the image.
Anyway if same name is created what's the best way to check
that? I was thinking of putting the image name field in DB as
a unique field. That would do it? Right?
Append a datetime to the filenames, or use a folder per date?
If want to create a unique filename, and are using PHP4.3.2 or better, use
fopen() with the 'x' or 'x+' mode, rather than
file_exists().
Something like the function below,
The filename parameter is passed by reference, so you can retrieve the
filename the function actually created.
Returns a FALSE, or a standard file handle which can fwrite() etc.
function createFileWithUniqueName($filename)
{
$f = @fopen($filename, 'x');
if ($f === FALSE)
{
$pathInfo = pathinfo($filename);
$dirname = $pathInfo['dirname'];
$basename = $pathInfo['basename'];
$extension = $pathInfo['extension'];
if (!empty($dirname))
$dirname .= DIRECTORY_SEPARATOR;
if (!empty($extension))
{
$extension = '.'.$extension;
$basename = substr($basename, 0, -strlen($extension));
// Remove extension from basename
}
$prefix = $dirname.$basename.'_';
/* Keep trying to create new files ... The $n 100 is just to
prevent any extreme situations happening */
for ($n = 1; $f === FALSE $n 100; ++$n)
{
$name = $prefix.$n.$extension;
$f = @fopen($name, 'x');
}
if ($f !== FALSE)
$filename = $name;
}
return $f;
}
$basename = 'test.txt';
$n = $basename;
$f = createFileWithUniqueName($n);
if ($f !== FALSE)
{
fwrite($f, 'test '.$n);
fclose($f);
}
$n = $basename;
$f = createFileWithUniqueName($n);
if ($f !== FALSE)
{
fwrite($f, 'test '.$n);
fclose($f);
}

[PHP] XML/HTML specific instructions
This is just an idea I'm (quite unsuccessfully) been working on.
It appears to me that PHP sits between a database and a web browser.
On the database side, something I would love to have is embedded SQL, as it
exists in some other languages such as C (for example, see:
http://www.csee.umbc.edu/help/oracle8/server.815/a68022/sql.htm)
At least, what the minimum I would like is to have the very same variable
types all the way from the database end to the browser end.
Anyway, Embedded SQL is to much to ask. What I was working on, though I got
nowhere due to my lack of experience with Yacc and Lex is to have HTML or
XML directly as part of the language (I will just say XML from now on, to
indicate both HTML and XML) .
You see, both PHP and XML are block structured. Nevertheless, when we
program PHP, we only see one set of blocks, those enclosed by curly
braces{}. Most IDEs even check those for pairing, and we have Code
Beautifiers to indent them properly. The other set of blocks, those
enclosed by XML tags are invisible to the program, though keeping track of
those blocks is just as important.
Moreover, logic indicates that one set of blocks is compatible with the
other. That is, if you are generating an XML block within an if (condition)
block, the XML block has to be closed, you can't just open it and leave it
open. When the if() block closes, the XML block has to as well. Can you
point any case when this might not be so? Don't bother, I can give you
examples myself, but good programming practice can straigten that code out
nicely.
So, this is what I thought. I probably re-invented the wheel and if anybody
can point me to the source, I'll be just as happy.
I would like to see a couple of additions to PHP, which could very well be
implemented as a pre-compiler, in
the form of two new instructions, TAG and ATT which could also be
abbreviated to and @.
The following piece of code show how to use them:
p {
@align 'center';
echo 'este es el texto del párrafo';
}
Which would produce, after precompiled:
echo 'p align=centereste es el texto del párrafo/p';
Just in case you wonder, yes, the text is in Spanish and it is alread
optimized in the sense that all the literal string segments that could be
strung together has been put in just one string in just a single call to
echo.
So, the TAG or instruction would be followed by a valid tag name and then
a statement. The statement, as usual, can be replaced by a statement block,
enclosed in curly braces. I don't see any need for the tag name to be
enclosed in any kind of quotes. A variable instead of a literal tag name
should also be valid. Thus:
$p = 'p';
$p { etc. }
would do the same. This syntax would prevent functions as a source of tag
names, which would be a very rare case and taking it under consideration
would really make the whole thing too cumbersome.
The ATT (attribute) or @ instruction is to be followed by a valid attribute
name and an expression providing the value. The attribute name can be the
value of a variable, so that
$attribute = 'align';
@$attribute 'center';
Once again functions cannot be used.
Why all these?
Basically, I don't want to keep track manually of how my XML blocks are
build.
Even a Code Beautifier would be able to handle the proper nesting of XML
(with these instructions) along PHP. The code would simply look good, and
that means it would be easy to get it right. Actually, while re-writing the
example code below, the brace matching in my IDE caught a missing curly
brace in one input instruction.
I would also add a declarative statement to handle XML validation. The
declaration would have a reference to a DTD or Schema that describes the XML
to be generated. Optionally, the declaration would also give an xpath
string which would indicate what part of the schema is being validated. This
would allow the declaration to be used in functions or classes where only
fragments of the full schema are being generated.
And, by the by, I wouldn't mind the precompiler to take ? as a synonym for
echo.
Please notice that I am not trying to solve any specific programming
problem, and yes, I could use templates (actually I do) and I could do a
library of functions to echo XML without my actually having to assemble the
XML strings. It doesn't matter how many layers you put in between your
application and your XML strings, in the end, at some point, you have to
echo some XML. It is not a problem I am trying to solve, it is a feature I
would like to see.
Just an example of a more substantial piece of code:
table {
tr {
th {
@rowspan 2;
@valign top;
// Here I am using the ? instead of echo
? 'Direccioacute;n';
}
td {
input {
@name 'Direccion1';
@size 50;
@value $row['Direccion1'];
}
}
}

The mail() function allows you to specify additional headers that go into the mail. Delivery acknowledgement is done using specific headers, the exact format of which I don't know off hand.

Glad to have helped (though someone else beat me to the punch with the right answer!) You'll get the hang of it -- the way I learned is to write out your tag that you'd like to use like this: a href=$urltext here/a Then go through and escape the characters that need it: a href=\$url\text here/a You can place variables into a string, but if you are using a function to work on that variable, you must concatenate it. a href=\$url\ . htmlentities($url) . /a; (needs concatenation) a href=\$url\$url/a; (no function used, no concatenation necessary) Good luck!

change it if it's what you expected:
$color = #FF;
if($color = #FF) {
$color = #00;
//output
} else {

Re: [PHP] How to format every secound row in a database result
I've used the mod (%) function to do this, which also gives you the flexibility
of defining how many lines to alternate the colors or do whatever you need to
do every X lines.
Another method (and forgive me if this was mentioned, I didn't see it yet) is
to use a bitwise NOT to flip-flop a value. I think I did something like this
before:
$bgcolors[0] = #FF;
$bgcolors[1] = #00;
$a = 0;
echo 'table\n';
for ($i = 0; $i = 100; $i++) {
$a = ~$a
echo 'trtd bgcolor=' . $bgcolors[$a] . 'Some text/td/tr\n';
}
echo '/table\n';
Maybe it was 0 and -1 instead of 0 and 1.. I forget. But you get the idea.
The $a = ~$a flips the value of $a back and forth. You only have two options
but that maybe all you need.
And hey.. I've been known to do some goofy things so if there's some major
drawback to this in processing time or if I'm just stupid in some way, that's
cool.. feel free to speak up. But it does present another way to do what was
requested and the theory might help someone at least :)

[PHP] Sourcelabs releases AMP Stack and Test Data
SourceLabs released its AMP Stack and associated test data this morning. Please forgive the (debatable) spam in advance; this post does contain pointers to useful test information for capacity planners who are building out AMP infrastructure for demanding deployments and others who are working with PHP. Consisting of pre-configured versions of Apache, MySQL and PHP, the SourceLabs AMP Stack provides documented test results to give customers a higher level of confidence in the reliability, scalability and security of AMP than has been available to date. The stack is available free of charge from our website at www.sourcelabs.com/AMPstack.htm. This initial release of the stack has been tested per three of the Seven CERT7 dependability criteria: unit testing, security hardening and scalability. CERT7 augments the testing approaches that are typical of open source projects by adding tests that focus on the performance, stability and scale characteristics of integrated systems. Not only is this the first time that an integrated open source stack has been tested this way, this is the first time the results of the tests and the tests themselves (provided through GPL) have been made publicly available. While many enterprise software vendors do this kind of testing, they don't open the process for customer review. We think that open testing is a big part of the future of open source, and we're looking forward to the community taking our testing harness and adapting it to their needs. Some highlights of our findings from the test process: . We performed a 72 hour burn-in acceptance test utilizing a subset of the CERT7 scalability tests, resulting in 70-100% CPU utilization on a 2 CPU Hyper-threaded machine, confirming the absence of detectable memory leaks for these scenarios. . Over 7,000 individual security checks were performed, showing that a number of potential security vulnerabilities exist in default configurations of components of the AMP stack. We configured the AMP Stack to protect against these vulnerabilities. CERT7 Scalability tests were performed in three areas: Static HTML, Computational PHP and Database scalability, resulting in scale-out and configuration recommendations for AMP deployments. Key findings include: . Apache Web Server scalability was limited by bandwidth in all cases tested, and not CPU or memory capacity. . PHP processing scaled linearly with respect to CPU capacity. For capacity planning purposes, this means that the desired number of servers running Apache Web Server/PHP for a given application can be calculated based on the processing speed of an individual user scenario. For this, an understanding of the processing speed, the number of concurrent users, and the desired user experience/response time would be used. . MySQL scalability was limited by memory. For capacity planning purposes, MySQL implementations should be optimized for the greatest available memory rather than adding CPU capacity. Complete Test results are at http://www.sourcelabs.com/SourceLabsApacheMySQLPHPTestResults.pdf To promote the new stack we are also announcing a maven contest in our forums. Users that download our AMP stack and provide feedback, make clever puns, ask or answer questions in our forum qualify for the grand prize: A 100 Watt Marshall Guitar Amplifier and a Fender Stratocaster Electric Guitar. Just like the SourceLabs AMP stack, this is the kit that will let you go to 11. Each Friday afternoon for eleven weeks we will be giving away a weekly prize consisting of an Ipod Shuffle and a DVD copy of This is Spinal Tap, culminating in the announcement of our grand prize winner on June 10, 2005.

Another way to put it would be: ...because in most real-world scripts, the execution time for this kind of operation (the string parsing) is negligible compared to the script's total execution time. So even if you could reduce the time it took to parse strings to nothing, you wouldn't speed up the total execution time very much. If you want to optimize the performance of your scripts, there are probably a lot of other things that should be much higher on your priority list than substituting double quotes with single quotes. /Mattias Thorslund -- More views at http://www.thorslund.us -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] XML/HTML specific instructions
Satyam wrote:
This is just an idea I'm (quite unsuccessfully) been working on.
It appears to me that PHP sits between a database and a web browser.
On the database side, something I would love to have is embedded SQL, as it
exists in some other languages such as C (for example, see:
http://www.csee.umbc.edu/help/oracle8/server.815/a68022/sql.htm)
At least, what the minimum I would like is to have the very same variable
types all the way from the database end to the browser end.
Anyway, Embedded SQL is to much to ask. What I was working on, though I got
nowhere due to my lack of experience with Yacc and Lex is to have HTML or
XML directly as part of the language (I will just say XML from now on, to
indicate both HTML and XML) .
http://www.php.net/sqlite
You see, both PHP and XML are block structured. Nevertheless, when we
program PHP, we only see one set of blocks, those enclosed by curly
braces{}. Most IDEs even check those for pairing, and we have Code
Beautifiers to indent them properly. The other set of blocks, those
enclosed by XML tags are invisible to the program, though keeping track of
those blocks is just as important.
Moreover, logic indicates that one set of blocks is compatible with the
other. That is, if you are generating an XML block within an if (condition)
block, the XML block has to be closed, you can't just open it and leave it
open. When the if() block closes, the XML block has to as well. Can you
point any case when this might not be so? Don't bother, I can give you
examples myself, but good programming practice can straigten that code out
nicely.
I don't agree with you here at all. Why should PHP (which is not a XML
parsing/validating engine) give two hoots about how you are generating
content?
So, this is what I thought. I probably re-invented the wheel and if anybody
can point me to the source, I'll be just as happy.
I would like to see a couple of additions to PHP, which could very well be
implemented as a pre-compiler, in
the form of two new instructions, TAG and ATT which could also be
abbreviated to and @.
The following piece of code show how to use them:
p {
@align 'center';
echo 'este es el texto del párrafo';
}
Which would produce, after precompiled:
echo 'p align=centereste es el texto del párrafo/p';
Here you are building a templating engine into PHP, which IMHO is not a
very good idea. Why? Many reasons. You'd have to compensate for other
forms of markup, such as XML, XHTML, the different XML standards
floating out there (like Docbook). Others might say what about CSS? I
can go on and on here.
Just in case you wonder, yes, the text is in Spanish and it is alread
optimized in the sense that all the literal string segments that could be
strung together has been put in just one string in just a single call to
echo.
So, the TAG or instruction would be followed by a valid tag name and then
a statement. The statement, as usual, can be replaced by a statement block,
enclosed in curly braces. I don't see any need for the tag name to be
enclosed in any kind of quotes. A variable instead of a literal tag name
should also be valid. Thus:
$p = 'p';
$p { etc. }
would do the same. This syntax would prevent functions as a source of tag
names, which would be a very rare case and taking it under consideration
would really make the whole thing too cumbersome.
The ATT (attribute) or @ instruction is to be followed by a valid attribute
name and an expression providing the value. The attribute name can be the
value of a variable, so that
$attribute = 'align';
@$attribute 'center';
Once again functions cannot be used.
Why all these?
Basically, I don't want to keep track manually of how my XML blocks are
build.
This is not the job of the programming language either. PHP is not a
XML validating/generating engine. Its your job (as the developer) to
make sure what your program creates is valid.
Even a Code Beautifier would be able to handle the proper nesting of XML
(with these instructions) along PHP. The code would simply look good, and
that means it would be easy to get it right. Actually, while re-writing the
example code below, the brace matching in my IDE caught a missing curly
brace in one input instruction.
There are already technologies that beautify XML (namely xsl); and
programs that will do this for you. Again, this should not be in the
core of PHP since part of the attraction and popularity of PHP is that
its extremely flexible.
I would also add a declarative statement to handle XML validation. The
declaration would have a reference to a DTD or Schema that describes the XML
to be generated. Optionally, the declaration would also give an xpath
string which would indicate what part of the schema is being validated. This
would allow the declaration to be used in functions or classes where only
fragments of the full schema are being generated.
And, by the by, I wouldn't mind the precompiler
[PHP] image_type
Hello, I was under impression that php automatically gives values to image_type and image_name if one tries to upload image from a web form if the name of the uploaded image field is image. If I do this I can see that there is a path for the uploaded image in a variable but the echo won't print anything.

[PHP] Re: asking comment
If you are storing the name of the uploaded image in a table (mySQL DB),
then the row in which you gonna store this name must have a unique id
(auto_increment field) ... why don't you use this id as your image name.
here you'll NEVER have the same image name.
Example
You have an HTML form where surfer enter details + upload an image. On
submitting the form, the PHP script stores all the details + uploads the
image and put it in the right folder on the server.
Table myTable
id int(6) unsigned auto_increment
imagename varchar(15)
otherdetails varchar(255)
once you insert a row in the table, get the id of the row. Use this id to
name ur image.
steps:
1. mysql_query(insert into myTable (imagename, otherdetails) values ('',
'$otherdetails'));
2. get rowid - mysql_insert_id()
3. rename image to id.ext
4. update row in table: update myTable set imagename = 'id.ext' where id =
'id'
You may use this script to do step 3

Hello,
I got a bit frustrated with image upload stuff with different image name
problems. So I created a system that gives the uploaded imaged a random
numeric name between 1-10 000 000 and saves the file to a server folder
and
the image name to mysql DB.
Is there a so sort of a problem here that I am not thinking of? I only can
imagine problem that the rand() gives the same value twice. But I cant see
this as a major problem because there would be maybe not more than 1000
uploaded pictures. So the chance is at worst something like 1:10 000 that
same name is created to the image.
Anyway if same name is created what's the best way to check that? I was
thinking of putting the image name field in DB as a unique field. That
would
do it? Right?
Thanks again
-Will

For the sake of testing, my script only print out the url-link to those

f=1
http://feeds.example.com/news/world/quake.html
cat=somecat
The output for line 1 is truncated to 'f=1' and the output of line 3 is
truncated to 'cat=somecat'. ie, the script only took the last parameter of
the url-link. The output for line 2 is correct since it has NO parameters.
I am not sure what I have done wrong in my script. Is it bcos the RSS spec
says that you cannot have parameters in URL ? Please advise.

So basically, I run the test 20 times, include 1000 _different_ files
for both single and double quotes in each test, and come up with a mean
of about 3 one-thousands of a second in favor of double quotes. Not
totally scientific but produces a fairly accurate result.
You on the other hand, run a test including the _same_ file 10,000 times
(which brings into play error handling if you define a function in that
include file) and produce a result with a difference of about 7
one-hundredth of a second. A bit less scientific, but still produces a
fairly accurate result.
With all that said...
1) The time difference in either test if way too small to make a
difference.
2) It's a far cry from one of your earlier posts which read, Welli
