If someone wants to add slashes to multidimensional array directly, can use recursive (pass-by-reference) function like this:
<?php
function slashit(&$aray, $db_link)
{
  foreach ($aray as $key => &$value)
   if(is_array($value)) slashit($value, $link);
   else $aray[$key] = mysql_real_escape_string($value, $db_link);
}

// Test:
$fruits = array (
    "fruits"  => array("a" => "or'ange", "b" => "ban'ana", "c" => "apple'"),
    "numbers" => array(1, 2, 3, 4, 5, 6),
    "holes"   => array("fir'st", 5 => "sec'ond", "thir'd"),
    "odma"    => "jugo'slavija"
);

// You have to make link to the database or can use addslashes instead of mysql_real_escape_string and remove $link from function definition

slashit($fruits, $dbLink);
echo "<pre>"; print_r($fruits); echo "</pre>";
?>

// Output:
Array
(
    [fruits] => Array
        (
            [a] => or\'ange
            [b] => ban\'ana
            [c] => apple\'
        )

    [numbers] => Array
        (
            [0] => 1
            [1] => 2
            [2] => 3
            [3] => 4
            [4] => 5
            [5] => 6
        )

    [holes] => Array
        (
            [0] => fir\'st
            [5] => sec\'ond
            [6] => thir\'d
        )

    [odma] => jugo\'slavija
)
