Question

I’m using some php functions for security.

function whileToArray($qr)
    {
        while($rs = mysql_fetch_assoc($qr))
        {
            $data[] = $rs;
        }
        $data = array_map('htmlspecialchars_decode',$data);
        $data = array_map('htmlentities',$data);
        return $data;
    }

When i running this code, I get;

Warning: htmlspecialchars_decode() expects parameter 1 to be string, array given in C:\AppServ\www\bigbeng\classes\get.class.php on line 22
Warning: htmlspecialchars_decode() expects parameter 1 to be string, array given in C:\AppServ\www\bigbeng\classes\get.class.php on line 22

print_r($data):

Array ( [0] => Array ( [kategori_id] => 1 [kategori_adi] => Spor )
        [1] => Array ( [kategori_id] => 2 [kategori_adi] => Siyaset ) )

How can i use these functions with array?

Answer 1

array_map works with 1D array not on multidimensional array. so try with below function

function array_map_recursive($fn, $arr) {
    $rarr = array();
    foreach ($arr as $k => $v) {
        $rarr[$k] = is_array($v)
            ? array_map_recursive($fn, $v)
            : $fn($v); // or call_user_func($fn, $v)
    }
    return $rarr;
}

then call

 $data = array_map_recursive('htmlspecialchars_decode',$data);
