preg_match(): Compilation failed: regular expression too large at offset 0 The regular expression is 34,745 bytes long. <?php $regExp = 'huge regexp with 34,745 bytes'; echo '<pre>strlen($regExp) = ', strlen($regExp), "\n"; echo preg_match($regExp, 'sudokusweb.com'); echo '</pre>'; ?> This error shows in Fedora Core 5 - PHP 5.4.1 The same code works in a shared host running PHP 4.3.11: http://allthehosts.com/testregex.php The code including the regexp can be downloaded from: http://allthehosts.com/testregex.txt LIMITATIONS section of http://www.pcre.org/pcre.txt "The maximum length of a compiled pattern is 65539 (sic) bytes if PCRE is compiled with the default internal linkage size of 2." Then I suppose FC5 does not compile it with the default size of 2. Why? Regards, Clodoaldo Pinto
