note 118929 added to function.array-diff

This function comes in handy if we want to compare two array values only For example we want to make a quick check on some required $_POST parameters: function required_array($required_array_values, $dynamic_array_values){ return (count(array_diff( $required_array_values, $dynamic_array_values )) > 0) ? false : true; } // we expect $_POST['change_password'][new, old, repeat] $required_params = required_array( array('old','new','repeat'), array_keys($_POST['change_password']) ); if( !$requred_params ){ die('error: all parameters are required!'); }else{ echo 'good to go'; } ---- Server IP: 72.52.91.14 Probable Submitter: 80.90.95.34 ---- Manual Page -- http://php.net/manual/en/function.array-diff.php Edit -- https://master.php.net/note/edit/118929 Del: integrated -- https://master.php.net/note/delete/118929/integrated Del: useless -- https://master.php.net/note/delete/118929/useless Del: bad code -- https://master.php.net/note/delete/118929/bad+code Del: spam -- https://master.php.net/note/delete/118929/spam Del: non-english -- https://master.php.net/note/delete/118929/non-english Del: in docs -- https://master.php.net/note/delete/118929/in+docs Del: other reasons-- https://master.php.net/note/delete/118929 Reject -- https://master.php.net/note/reject/118929 Search -- https://master.php.net/manage/user-notes.php
