Using mysql_real_escape_string in a multidimensional array in php -

i working on big script generate string or array or multidimensional array want use mysql_real_escape_string array / string tried below code

function check($data) {     if(!is_array($data)) {         return mysql_real_escape_string($data);     } else if (is_array($data)) {        $newdata = array();        foreach($data $datakey => $datavalue){              if(!is_array($datavalue)){                  $key = mysql_real_escape_string($datakey);                  $value = mysql_real_escape_string($datavalue);                  $newdata[$key] = $value;              }         }         return $newdata;      }   } 

if use check('saveme'); returns value

if pass array returns corrent value [ check(array('a','b','c',1,2,3)) ]

if pass multidimensional array [check(array(array('a',array('a','b','c',1,2,3),'c',1,2,3),'b',array('a','b','c',1,2,3),1,2,3))]

a kind note want use mysql_real_escape_string array key too.

you can use array_walk_recursive function, go throw leaves of array, , escape values:

array_walk_recursive($array, function(&$leaf) {     if (is_string($leaf))        $leaf = mysql_real_escape_string($leaf); }); 

also, follow data consistency rules, , not use !is_array(), is_string(), because mysql_real_escape_string takes string params, not !string.

unfortunately, array_walk_recursive designed so, can't edit keys. if need edit keys, may want write own recursive function. don't want copy answer, can find here
