Warning: preg_match() expects parameter 2 to be string, array given in e:\test.php on

If I understand correctly what you're trying to do, you could loop through the array, check each string value in the array with preg_match and break out of it if you find a match.

e.g.

PHP Code:

$arr = array();//Add data into the array here
for ($i = 0; $i < count($arr); $i++) {
    $tt = preg_match("[0-9]", $arr[$i]);
    if ($tt == 1) {
          break;
    }
}
