Escape array Solution with recursive addslashes function

Escaping an array with a recursive addslashes function
There is an array, possibly multidimensional, with some values with special symbols such as "I escaped with recursion plus addslashes ()

It's not working, help, see what's wrong.
$arr =array (' II ', array (' one ' = ' "EC" ', ' =>5 '));
Function T (& $arr) {
foreach ($arr as $v) {
if (is_string ($v)) {
$arr []=addslashes ($v);
}else{
T ($v);
}
}
}
T ($arr);
echo "

";
Print_r ($arr);
Echo '

';

------Solution--------------------
You compare yourself.

$arr =array (' II ', array (' one ' = ' + ' EC ', ' =>5 '), ' AA ' a ');
Function T (& $arr) {
    foreach ($arr as $k = = $v) {
        if (is_string ($v)) {
            $arr [$k] = addslashes ($v);
        }else{
            $arr [$k] = t ($v);
        }
    }
    return $arr;
}
T ($arr);
echo "
";
Print_r ($arr);
Echo '
';

------Solution--------------------

$arr = Array (' II ', array (' one ' = ' = ' EC ' ", ' =>5 '));
Array_walk_recursive ($arr, function (& $v) {$v = Addslashes ($v);});
Print_r ($arr);

Array
(
    [0] = ii\ "
    [1] = = Array
        (
            [One] = Ec\ '
            [5] + =
        )

)

------Solution--------------------
Change it to this.

Function T (& $arr) {
foreach ($arr as $key = = $v) {
if (is_string ($v)) {
$arr [$key]=addslashes ($v);
}else{
T ($arr [$key]);
}
}
}

------Solution--------------------
Change it a little bit more.

Function T (& $arr) {
    foreach ($arr as $key = = $v) {
        if (Is_array ($v)) {
            T ($arr [$key]);
        }else{
            $arr [$key]=addslashes ($v);
}
    }
}

$arr =array (' II ', array (' one ' = ' "EC" ', ' one ', ' + ' 5 '));
T ($arr);

Print_r ($arr);
