note 65182 added to function.preg-replace-callback

it is much better on preformance and better practice to use the preg_replace_callback function instead of preg_replace with the e modifier. function a($text){return($text);} // 2.76 seconds to run 50000 times preg_replace("/\{(.*?)\}/e","a('\\1','\\2','\\3',\$b)",$a); // 0.97 seconds to run 50000 times preg_replace_callback("/\{(.*?)\}/s","a",$a); ---- Server IP: 216.194.113.175 Probable Submitter: 24.115.146.152 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace-callback.php Edit -- http://master.php.net/note/edit/65182 Del: integrated -- http://master.php.net/note/delete/65182/integrated Del: useless -- http://master.php.net/note/delete/65182/useless Del: bad code -- http://master.php.net/note/delete/65182/bad+code Del: spam -- http://master.php.net/note/delete/65182/spam Del: non-english -- http://master.php.net/note/delete/65182/non-english Del: in docs -- http://master.php.net/note/delete/65182/in+docs Del: other reasons-- http://master.php.net/note/delete/65182 Reject -- http://master.php.net/note/reject/65182 Search -- http://master.php.net/manage/user-notes.php
