I know those limitations. Is there a way to work with 9344 symbols long blocks on Windows? Previous Comments: ------------------------------------------------------------------------ [2003-10-04 22:04:17] [EMAIL PROTECTED] >From http://www.pcre.org/pcre.txt, LIMITATIONS: "The maximum length of a subject string is the largest positive number that an integer variable can hold. However, PCRE uses recursion to handle subpatterns and indefinite repetition. This means that the available stack space may limit the size of a subject string that can be processed by certain patterns." This propably should be mentioned in our manual pages too. (On Linux, the example script worked fine with 9344 chars between the tags, but 9345 crashed) ------------------------------------------------------------------------ [2003-10-04 19:56:54] ilya at lebedev dot net Description: ------------ Regular expression from the J.Friedl's "Mastering regular expressions" book that matches pair html tags: #<tag([^>]*)>(((?!</?tag(?:[^>]*)>).)*)</tag>#si When between <tag> and </tag> are more then 2100 bytes (symbols), Apache crashes. Same happens without "s" modifier, if string has no "newline" codes. Reproduce code: --------------- === preg_replace("#<tag([^>]*)>(((?!</?tag(?:[^>]*)>).)*)</tag>#si","","<tag > 2200 symbols</tag>"); === or === function callback (&$m) { return "";}; preg_replace_callback ("#<tag([^>]*)>(((?!</?tag(?:[^>]*)>).)*)</tag>#si","callback","<tag> 2200 symbols </tag>"); === Expected result: ---------------- Match blocks bigger then 2100 symbols long. Actual result: -------------- With more then 2100 sybmols between tags Apache crashes. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25754&edit=1
