i trying json_encode array since there special characters, found out need $toreturn = array_map('utf8_encode', $toreturn); i'm getting error. code below.

$toreturn = array_map('utf8_encode', $toreturn); echo json_encode($toreturn);

im getting error in page.

( ! ) warning: utf8_encode() expects parameter 1 string, array given in c:\wamp\www\resh\backend.php on line 39

this easy can't find error is.

thanks in advance.

this happning because array_map() pass data contains array instead. try - 

$toreturn = array_map('encode_all_strings', $toreturn);  function encode_all_strings($arr) {     foreach($arr $key => $value) {         $arr[$key] = utf8_encode($value);     }     return $arr; }
