Description:
The following preg_replace breaks when the string is = 24999
characters. Works perfectly fine with 24998 characters and worked fine
with any strings in PHP 5.1.5.
Reproduce code:
---
?php
$string = str_repeat('a', 10);
echo
preg_replace('#(^.*|.*)(\[(php|html|noparse)\].*\[/\\3])(.*|.*$)#siUe',
'', $string);
?
Expected result:
100.000 times 'a'
Actual result:
--
nothing

#36631 [NEW]: Prepared statements failing with no apparent reason
From: ludvig dot ericson at gmail dot com Operating system: Windows XP PHP version: 5CVS-2006-03-06 (snap) PHP Bug Type: MySQLi related Bug description: Prepared statements failing with no apparent reason Description: When I run this code: http://nopaste.php-q.net/196469 (I removed the LIMIT on line 48 too) I get two warnings: Warning: mysqli_stmt::bind_param() [function.bind-param]: Number of variables doesn't match number of parameters in prepared statement in C:\Web\Apache\lnkrec\core\UserSystem.inc.php on line 50 Warning: mysqli_stmt::bind_result() [function.bind-result]: Number of bind variables doesn't match number of fields in prepared statement. in C:\Web\Apache\lnkrec\core\UserSystem.inc.php on line 52 I'm thinking this is really weird since the amount of parameters are just as many as there should be. I have tested my MySQL query outside PHP, and it works fine syntactically. Futhermore, $stmt-param_count is 0. The Database class is defined as: http://nopaste.php-q.net/196448 and therefore seemingly transparent in this case. -- Edit bug report at http://bugs.php.net/?id=36631edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=36631r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=36631r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=36631r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=36631r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=36631r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=36631r=needtrace Need Reproduce Script:http://bugs.php.net/fix.php?id=36631r=needscript Try newer version:http://bugs.php.net/fix.php?id=36631r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=36631r=support Expected behavior:http://bugs.php.net/fix.php?id=36631r=notwrong Not enough info: http://bugs.php.net/fix.php?id=36631r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=36631r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=36631r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=36631r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=36631r=dst IIS Stability:http://bugs.php.net/fix.php?id=36631r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=36631r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=36631r=float No Zend Extensions: http://bugs.php.net/fix.php?id=36631r=nozend MySQL Configuration Error:http://bugs.php.net/fix.php?id=36631r=mysqlcfg

#33652 [NEW]: $this not available in a variable variable
From: ludvig dot ericson at gmail dot com
Operating system: Windows XP
PHP version: 5.0.4
PHP Bug Type: Variables related
Bug description: $this not available in a variable variable
Description:
Using variable variables ($$MyVar) in classes, through functions that is,
doesn't allow $this to be used.
I tried with $this (notice the $) too, no difference.
A workaround is to check the object name, if it's this you could
$this-$Mem instead.
Reproduce code:
---
?php
class Foo {
public $MyVal = Test;
public Bar($Obj, $Mem) {
return ${$Obj}-$Mem;
}
}
$TheObject = new Foo();
$Objname = this;
$Memname = MyVal;
echo $TheObject-Bar($Objname, $Memname);
?
Expected result:
I expect it to output Test
Actual result:
--
Notice: Undefined variable: this in (filepath) on line 6
Notice: Trying to get property of non-object in (filepath) on line 6
