This is a PCRE library issue, not the PHP extension. Probably related to item 23 in http://pcre.org/changelog.txt Previous Comments: ------------------------------------------------------------------------ [2008-05-06 14:28:51] php dot net at waisse dot org Description: ------------ Using classes in preg_* functions worked before 5.2.6 After upgrading to 5.2.6 classes like [:space:] no more work I had to replace all [:class:] with things like \s Reproduce code: --------------- the regular expression : list($header) = preg_split(',<(item|entry)[:[:space:]>],', $rss, 2); worked before PHP 5.2.6 no more working now, I had to change this to : list($header) = preg_split(',<(item|entry)[:\s>],', $rss, 2); and it works again. Expected result: ---------------- see http://www.pcre.org/pcre.txt it says that pcre supports classes ( POSIX CHARACTER CLASSES Perl supports the POSIX notation for character classes. This uses names enclosed by [: and :] within the enclosing square brackets. PCRE also supports this notation. ) so the classes should work with PHP 5.2.6 pcre ( preg_* fucntions ) this always worked before and thousands of websites are using them. The above code is sandard spip ( http://spip.net ) code for years and this feature change in PHP 5.2.6 makes that all spip websites no more work with PHP 5.2.6. Probably many other CMS will have the same problem. Could anyone confirm that this is a PHP 5.2.6 pcre implementation bug before we try to insert a workaround in spip code ? The regular expression seems ok since this works after replacing [:space:] with \s . Actual result: -------------- Warning: preg_split() [function.preg-split]: Compilation failed: POSIX named classes are supported only within a class at offset 13 in /www/spanish.feeder.ww7.be/html/ecrire/inc/syndic.php on line 145 Warning: preg_match_all() [function.preg-match-all]: Compilation failed: POSIX named classes are supported only within a class at offset 14 in /www/spanish.feeder.ww7.be/html/ecrire/inc/syndic.php on line 166 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44928&edit=1
