It's not, the forach way is about 4.5 times faster than your other method. Use this code to compare : <? for( $i=0; $i<10000; $i++ ) { $db[$i] = " dskjdskjdlskjdlskjldskdjslkjd "; } echo microtime()."\n"; array_walk($db ,create_function('&$arr','$arr=trim($arr);')); echo microtime()."\n\n\n"; for( $i=0; $i<10000; $i++ ) { $db[$i] = " dskjdskjdlskjdlskjldskdjslkjd "; } echo microtime()."\n"; foreach ($db as $key=>$value) { $db[$key]=trim($value); } echo microtime()."\n"; ?> ---- Manual Page -- http://www.php.net/manual/en/function.trim.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+46531 Delete -- http://master.php.net/manage/user-notes.php?action=delete+46531&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+46531&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+46531&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+46531&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+46531&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+46531&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+46531&report=yes Search -- http://master.php.net/manage/user-notes.php
