Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Previous Comments: ------------------------------------------------------------------------ [2009-04-16 16:44:58] jimriver76 at yahoo dot co dot uk The way I 'fixed' it is uncommenting the pcre.recursion_limit line in php.ini ------------------------------------------------------------------------ [2009-04-16 15:10:19] jimriver76 at yahoo dot co dot uk Description: ------------ Since Feb 2009, all php scripts in my server suddently and selectively produced an curious error message in php log as following: [code] [16-Apr-2009 22:03:00] PHP Fatal error: Nesting level too deep - recursive dependency? in D:\websites\nameclub\include\common.inc.php on line 56 [/code] This proplem continued even after I upgrade to the current 5.2.9 version. After checking all those lines of code, I found some similarities of that issue. They always caused by preg_replace or preg_match: [code] $boardurl = 'http://'.$_SERVER['HTTP_HOST'].preg_replace("/\/+(api|archiver|wap)?\/*$/i", '', substr($PHP_SELF, 0, strrpos($PHP_SELF, '/'))).'/'; [/code] [code] // $cip = 124.227.153.46 preg_match("/[\d\.]{7,15}/", $cip, $cips); [/code] Another curious characteristic is that it dosen't happen always. Instead, it ran into this problem only at a 1/3 chance. Normally, after I refleshed the same page, it worked just fine. That is why I believe it should be reported as a bug. Btw, I could provide some help if one of you ever have this kind of problem. The way I 'fixed' it is uncomment the pcre.recursion_limit line ;pcre.recursion_limit=100000 I don't know why but it just fixed the issue perfectly for me. Yes I search a lot by the 'Nesting level too deep' keywords, but found none of them related to pcre extension, which I believe that mine has connection with. Reproduce code: --------------- $boardurl = 'http://'.$_SERVER['HTTP_HOST'].preg_replace("/\/+(api|archiver|wap)?\/*$/i", '', substr($PHP_SELF, 0, strrpos($PHP_SELF, '/'))).'/'; ... // $cip = 124.227.153.46 preg_match("/[\d\.]{7,15}/", $cip, $cips); Expected result: ---------------- null ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=47989&edit=1
