note 49177 added to function.preg-match

This is another way of implimenting array_preg_match. It also shows use of the array_walk() and create_function() functions. <?php // array_preg_match // make sure $subject is an array and it will return an array // of all the elements in $subject that preg_match the // $pattern. function array_preg_match($pattern, $subject, $retainkey = false){ $matches = ''; //make sure it's empty array_walk($subject, create_function('$val, $key, $array', 'if (preg_match("' . $pattern . '", "$val")) $array['. ($retainkey ? '$key':'') .'] = $val;'), &$matches); return $matches; } ?> kalon mills ---- Manual Page -- http://www.php.net/manual/en/function.preg-match.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+49177 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+49177&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+49177&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+49177&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+49177&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+49177&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+49177&report=yes Search -- http://master.php.net/manage/user-notes.php
