note 109074 added to function.preg-replace-callback

From PHP 5.3 you can use an anonymous function to pass local variables into the callback. <?php public function replace_variables( $subject, $otherVars ) { $linkPatterns = array( '/(<a .*)href=(")([^"]*)"([^>]*)>/U', "/(<a .*)href=(')([^']*)'([^>]*)>/U" ); $callback = function( $matches ) use ( $otherVars ) { $this->replace_callback($matches, $otherVars); }; return preg_replace_callback($this->patterns, $callback, $subject); } public function replace_callback($matches, $otherVars) { return $matches[1] . $otherVars['myVar']; } ---- Server IP: 113.20.13.217 Probable Submitter: 60.240.128.121 ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace-callback.php Edit -- https://master.php.net/note/edit/109074 Del: integrated -- https://master.php.net/note/delete/109074/integrated Del: useless -- https://master.php.net/note/delete/109074/useless Del: bad code -- https://master.php.net/note/delete/109074/bad+code Del: spam -- https://master.php.net/note/delete/109074/spam Del: non-english -- https://master.php.net/note/delete/109074/non-english Del: in docs -- https://master.php.net/note/delete/109074/in+docs Del: other reasons-- https://master.php.net/note/delete/109074 Reject -- https://master.php.net/note/reject/109074 Search -- https://master.php.net/manage/user-notes.php
