note 74969 added to function.preg-replace-callback

one way to 'pass' extra info other than just the matches and still use preg_replace_callback is to have your callback function be a class method, and just before you call preg_replace_callback, store the info in that class. I am using static methods/variables for my implementation; I'm not sure if its required. <?php class foo { private static $bar; public static function do_something($bar) { self::$bar = $bar; // store bar $input = $bar->get_somevar(); $pattern = "match me"; $output = preg_replace_callback($pattern, array('self', 'do_something_callback'), $input); return $output; } private static function do_something_callback($matches) { $bar = self::$bar; // retrieve bar // do stuff like $bar->get_someothervar(); return $replacement; } } ?> ---- Server IP: 69.39.81.135 Probable Submitter: 64.17.250.94 ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace-callback.php Edit -- https://master.php.net/note/edit/74969 Del: integrated -- https://master.php.net/note/delete/74969/integrated Del: useless -- https://master.php.net/note/delete/74969/useless Del: bad code -- https://master.php.net/note/delete/74969/bad+code Del: spam -- https://master.php.net/note/delete/74969/spam Del: non-english -- https://master.php.net/note/delete/74969/non-english Del: in docs -- https://master.php.net/note/delete/74969/in+docs Del: other reasons-- https://master.php.net/note/delete/74969 Reject -- https://master.php.net/note/reject/74969 Search -- https://master.php.net/manage/user-notes.php
