ehh, I thought you want the jobs on separate lines, sorry.
this can be achieved for example like this:
$prev_cname = "";
while ($aaa = mysql_fetch_array($result,MYSQL_ASSOC))
{
if ($aaa['companyName'] != $prev_cname) {
echo "<span class='navCompany'>{$aaa['companyName']}</span>";
}
echo "<span class='navArrow'> > </span><span class='navText'><a
href='single_page_t10.php?art=".$aaa['pix']."'>{$aaa['jobType']}</a></span>";
if ($aaa['companyName'] != $prev_cname) {
echo "<br/>\n";
$prev_cname = $aaa['companyName'];
}
}
hope that helps

Richard,
I had almost sent a message very similar to the one from Stut you're
complaining about here, but cancelled it because I expected you would
react the way you have, and I'd just waste energy.
One last try so that you know Stut is not alone in his assessment:
You might have actually played with a "simplified example", but judging
from your previous questions (and reactions to replies), you don't pay
much attention to your own observations, and/or you make too many
assumptions, and your subsequent fuckups bring you here.
You come claiming it's broken, you've tried everything, and show us code
that's simply broken. We never see the correct code you claim to have
tried (after you've been told to fix bugs in what you have shown).
Programming is not like waving a magic wand, it's not our fault the
computer does what you tell it instead of what you want it to do!

Hi,
I have come across what appears to be a bug in PHP, but one that I am
having difficulty writing test code for. Also, the bug only happens on a
Linux build of PHP - the code is working as expected on Windows. This is
on both PHP 5.2.0 and the very latest snapshots:
Windows: 5.2.1RC4-dev Jan 19 2007 16:16:57
Linux: PHP Version 5.2.1RC4-dev Jan 22 2007 11:54:28
(php5.2-200701221130.tar.gz)
The configure line is:
'./configure' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-curl'
'--with-freetype-dir=/usr' '--with-gd' '--with-gettext'
'--with-jpeg-dir=/usr' '--with-mysql' '--with-openssl'
'--with-pdo-mysql' '--with-pear' '--with-png-dir=/usr' '--with-zlib'
'--enable-calendar' '--enable-exif' '--enable-gd-native-ttf'
'--enable-pdo' '--enable-soap' '--enable-sockets'
and no 3rd party extensions are enabled.
The code that is causing the problem exists within a class in a function
called approve_friend. This is called by a "public" page with a
parameter provided in GET being passed to the function approve_friend:
$username = filter_input(INPUT_GET, 'username', FILTER_SANITIZE_STRING);
if (!empty($username))
{
if ($username != $_SESSION['user']['username'])
{
if ($core->user->add_friend($username))
{
echo 1;
}
else
{
echo 2;
}
}
}
There is code in place of echo 1 and echo 2 but it's not relevant. Here,
the code checks to make sure the username submitted is the not the same
as the currently logged in use. If not, it will execute the
$core->user->add_friend function.
add_friend runs through as follows:
1. Makes a call to $this->get_user where it gets data for the username
$username provided when calling the function. It returns an array.
$friend = $this->get_user(1, NULL, $username);
2. Grabs some data from the session about the currently logged in user
$user['name'] = filter_var($_SESSION['user']['name'],
FILTER_SANITIZE_STRING);
$user['user_id'] = filter_var($_SESSION['user']['user_id'],
FILTER_SANITIZE_NUMBER_INT);
$user['username'] = filter_var($_SESSION['user']['username'],
FILTER_SANITIZE_STRING);
$user['friend_count'] = filter_var($_SESSION['user']['friend_count'],
FILTER_SANITIZE_NUMBER_INT);
3. Checks to make sure $friend has a value
if (empty($friend))
{
return false;
}
4. Checks to make sure that the friend being added is not already added.
if (!empty($_SESSION['user']['friends']))
{
if (in_array($friend['user_id'], $_SESSION['user']['friends']))
{
return false;
}
}
This is the point at which there is a problem. If I add this code before #4:
print_r($_SESSION['user']['friends']);
echo $friend['user_id']; exit;
Then I get the following output:
Array ( [0] => 3 ) 3
i.e. $_SESSION['user']['friends'] is an array with the key 0 and the
value 3 and $friend['user_id'] has a value of 3. Therefore, the
in_array() check above will return true and the function will return
false. No further code in the function should execute. This is what
happens on Windows - 2 is output to the page because the add_friend
function has returned false.
Now, after #4, there is more code. This code is only supposed to execute
if the friend doesn't already exist - it adds the friend, increments the
friend count and sends an e-mail.
// Insert into friends
$core->database->exec('INSERT INTO users_friends SET user_id =
"'.$user['user_id'].'", user_friend_id = "'.$friend['user_id'].'",
status = 1');
$core->database->exec('INSERT INTO users_friends SET user_id =
"'.$friend['user_id'].'", user_friend_id = "'.$user['user_id'].'"');
// Update friend count
$core->database->exec('UPDATE users_insiders SET friend_count =
"'.++$user['friend_count'].'" WHERE user_id = "'.$user['user_id'].'"');
// E-mail sending code using phpmailer
return true;
On my Linux server, the function returns false at step #4 as it should
do, but it appears to continue executing. The friend count is
incremented and the page execution slows temporarily whilst the mail is
being sent (not a problem in testing). However, no e-mail actually gets
sent.
The key is that the function is returning false but it continues to
execute! If I stick in an exit; after the in_array() check at point #4,
this doesn't happen. There are no other places where this function is
called, and it is only called once.
Strangely, if I force the values of the 2 variables
before the in_array() check:
$_SESSION['user']['friends'] = array(0 => 3);
$friend['user_id'] = 3;
it reacts as expected - the function returns false and no further code
is executed.
Anyone have any suggestions?

David Mytton

Except in the former the function "continues executing" but in the

I also cannot see how the function can return false and execute the SQl

You have presented no proof that there's a bug in the PHP. What you
have presented looks like you have a bug, and the function gets called
more than once. Have you used a debugger? See http://xdebug.org/.

Yes, I know it looks like a bug in my code because I'm not able to write
a test case that can reproduce it simply enough to report as a bug -
hence why I am posting here. However, the behaviour I am describing
surely suggests some kind of issue somewhere in PHP itself.
My reasoning for this is if I echo the 2 variables I get:
Array ( [0] => 3 )
and
3
and the bug appears. But if I set them manually before the in_array test:
$_SESSION['user']['friends'] = array(0 => 3);
$friend['user_id'] = 3;
it works as expected. Am I wrong in thinking that this has to be a bug
in PHP?
I have used debug_backtrace() to find out what is going on as regards
how many times the function is being executed - that is the first thing
I checked because it does indeed suggest that it is being executed
multiple times, however, the back trace only reveals 1 call/execution.

A backtrace won't indicate multiple calls unless they are recursive. Try
add the following to your function:
<?php
static $foo = 0;
$foo++;
echo "I've been called $foo times\n";
?>
Cheers,
Rob.

Write tests that prove the code does what you think it does. Which of
these tests will break?

I still have no reason to believe it. Such a bug in PHP would require
memory corruption in the Zend engine. I run complex code in 5.2 on Linux,
and haven't seen anything like that.

You haven't shown the complete code, and what you *have* shown didn't
prove anything. Show me that it really gets past the return. var_dump() the
two things your comparing there with in_array() *after* the if() block,
and prove that it's in the same invocation as that return false.
function f()
{
static $x = 0;
$i++;
if (!in_array($friend, $friends)) {
var_dump("inside", $i, $friend, $friends);
return false;
}
var_dump("after", $i, $friend, $friends);
$core->database->exec(...);
}

Not suprprising. This code outputs
#0 f(1) called at [/usr/home/roman/tmp/scratch30:8]
#0 f(2) called at [/usr/home/roman/tmp/scratch30:8]
<?php
function f($i)
{
debug_print_backtrace();
}
foreach (range(1, 2) as $i) {
f($i);
}

At the very bottom of your function place another return with a string
like return 'FOUND THE END OF FUNCTION';
now, echo the return of the function and see if it really the return
function that you think it is that is returning false, or you are just
hitting the end of the function.

Yeah I tried this - I have confirmed that the return is the one I think
it is.
However, it seems this is actually being caused by some weirdness with
mod_rewrite. Basically, if I use the rewritten URL e.g.
example.com/section/addfriend/will/ which rewrites to
index.php?cmd=section/addfriend&username=will
I get this bug. But if I access
index.php?cmd=section/addfriend&username=will directly then it works fine.
This is definitely not a bug in my code but something to do with PHP,
Apache and/or mod_rewrite.
Unless anyone can suggest otherwise, I think it's going to be far too
complex to debug and produce a test case because of the complexity of
the code and working out where the bug actually is in PHP, Apache or
mod_rewrite. So I'm just going to work around it.

Can we see your mod_rewrite configuration? RewriteCond, RewriteRule, all
that jazz.

There are a number of rules but the only one that is relevant for this
page is:
RewriteRule ^section/addfriend(/)?(.*)$
index.php?cmd=section/addfriend&username=$2

Ok, what does RewriteLog contain for one such request?
RewriteLogLevel 9.

As you can see, the processing doesn't stop when it hits the RewriteRule
you thought was the only relevant (lines 6, 7):
91.84.87.114 - - [22/Jan/2007:19:20:56 +0000] [example.com/sid#91e8128][rid#9235280/initial] (3) [perdir /home/example/public_html/] applying pattern '^section/addfriend(/)?(.*)$' to uri 'section/addfriend/will'
91.84.87.114 - - [22/Jan/2007:19:20:56 +0000] [example.com/sid#91e8128][rid#9235280/initial] (2) [perdir /home/example/public_html/] rewrite 'section/addfriend/will' -> 'index.php?cmd=section/addfriend&username=will'
I think this paragraph from the apache manual applies to you:
# Note: When you use this flag, make sure that the substitution field is
# a valid URL! Otherwise, you will be redirecting to an invalid
# location. Remember that this flag on its own will only prepend
# http://thishost[:thisport]/ to the URL, and rewriting will continue.
# Usually, you will want to stop rewriting at this point, and redirect
# immediately. To stop rewriting, you should add the 'L' flag.

Alright. So if the rewrite rules were (and they are):
RewriteRule ^section/account(/)?$ index.php?cmd=section/account
RewriteRule ^section/addfriend(/)?(.*)$
index.php?cmd=section/addfiend&username=$2
RewriteRule ^section/approvefriend(/)?(.*)$
index.php?cmd=section/approvefriend&username=$
RewriteRule ^section/deletefriend(/)?(.*)$
index.php?cmd=section/deletefriend&username=$2
RewriteRule ^section(/)?$ index.php?cmd=section/index
RewriteRule ^anothersection(/)?(.*)$
index.php?cmd=listingnav&url=anothersection/$2
Where would the correct place be?

Are you sure you added the NS flag? It looks like the RewriteRules
are applied to the result of the original rewrite.
And, I see TWO requests for addfriend:
rewrite 'section/addfriend/will' -> 'index.php?cmd=section/addfriend&username=will'
rewrite 'section/addfriend/templates/js/jquery.js' -> 'index.php?cmd=section/addfriend&username=templates/js/jquery.js'

Here's a simple makefile I want PHP's exec to execute make on:

now when I use make from command line, it works as expected,
the keylist.txt file is created. however, when I use PHP exec
to run make on the makefile, the keylist.txt file is not generated.
* if keylist.txt does not need updating, PHP exec make works,
make says keylist.txt is up to date.
* if i remove redirection, PHP exec make shows that grep is
making the same matches as make from commandline.
Why does the redirection of the grep command (within the makefile)
only work when I execute make from the commandline but not from
PHP exec||shell_exec?
One sollution is to abandon redirection and get the output from
grep into a string and then get PHP to create keylist.txt, but
why do that?
Any help appreciated.

Does that line in the real Makefile begin with a tab? It must.
Why is it so roundabout about $(DEPS)/$(FILES)? The target *actuall*
depends on different files than those declared in the sources list!
What does $(DEPS) (and $(FILES)) contain?
This is what your Makefile does, BTW:
grep ^keywords keylist.txt ... > keylist.txt
Try it with this instead (rename keylist.txt to key.list), but make sure
you have at least one file ending in .txt in that directory first!):
KEYLIST := key.list
FILES := $(wildcard *.txt)
$(KEYLIST): $(FILES) ; grep '^keywords' $^ > $

attached mail follows:
I'm trying to get this but not quite there. I want to allow the following
characters.
A-Za-z0-9!#$%&()*;:_.'/\ and a space.
Is there a special order these need to be in or escaped somehow. For
example, if I just allow _' the ' is fine, if I add the other characters,
the ' gets preceded by a \ and an error is returned. If I take the ' out of
the sting below it works fine, I get no errors returned. I am also using
stripslashes on the variable.
This is my code. (although I have tried various things with it trying to get
it right)
if(preg_match("/^[-A-Za-z0-9!#%&\(\)\*;:_.\'\$ ]+$/", $string)) {
Thanks

Please read this page:
Pattern Syntax -- Describes PCRE regex syntax
http://ca.php.net/manual/en/reference.pcre.pattern.syntax.php
specifically the section on character classes:
http://ca.php.net/manual/en/reference.pcre.pattern.syntax.php#regexp.reference.squarebrackets
In PREG there are few characters that you need to escape in a
character class expression:
1) ^ must be escaped (\^) if it's the first character (it negates the
match when it's unescaped in the first position).
2) ] must be escaped (\]) unless it's the first character of the
class (it closes the class if it appears later and is not escaped).
3) \ must be escaped (\\) if you're referring to the backslash
character rather than using backslash to escape another character.
4) Control codes such as \b for backspace (not to be confused with \b
which means word boundary outside of a character class).
In addition, you may need to escape certain characters in PHP if
you're expressing the RegExp pattern in a quoted string, such as
single or double quotes (whichever you're using to quote the pattern):
'[\'"]' escape the apostophe
"['\"]" escape the quotation mark
Those are PHP escapes -- by the time PREG sees the pattern, the PHP
compiler has rendered it to:
['"]
And then of course there's the complication that both PREG and PHP
use the backslash as the escape character, so the pattern:
[\\] escape the backslash
must be expressed in PHP as:
[\\\\] escape the escape and the backslash
Interestingly, PHP compiles both \\\ and \\\\ as \\, go figure. I
use \\\\ to escape both backslashes to maintain some semblance of
logic and order in these eye-crossing expressions.
Because PHP requires quotes to be escaped, I find it easier to write
& debug patterns in PHP if I express them in heredoc where quoting
and most escaping is unnecessary:
$sPattern = <<<_
['"\\\\]
_;
becomes the PREG pattern ['"\\].
So to address your character class:
>A-Za-z0-9!#$%&()*;:_.'/\ and a space.
I'd use the pattern:
[A-Za-z0-9!#$%&()*;:_.'/\\ ]
where the only character I need to escape is the backslash itself.
In PHP this would be:
$sPattern = '[A-Za-z0-9!#$%&()*;:_.\'/\\\\ ]';
(escaped apostrophe & blackslash)
or:
$sPattern = "[A-Za-z0-9!#$%&()*;:_.'/\\\\ ]";
(escaped blackslash)
or:
$sPattern = <<<_
[A-Za-z0-9!#$%&()*;:_.'/\\\\ ]
_;
(escaped blackslash)

Paul
