PHP: Basic sanitzation that are still relevant today?
<p>Some years back, I use to do something similar to this on top of my script:</p>

<pre><code>ini_set('magic_quotes_runtime', 0);
ini_set('magic_quotes_sybase', 0);
ini_set('url_rewriter.tags', '');
ini_set('session.use_trans_sid', 0);

function clean_input ($arr)
{
    if (!get_magic_quotes_gpc())
        $arr = array_map('addslashes', $arr);

    return $arr;
}

$_GET = clean_input($_GET);
$_POST = clean_input($_POST);
$_COOKIE = clean_input($_COOKIE);
$_REQUEST = clean_input($_REQUEST);
</code></pre>

<p>Are this still relevant today at least in PHP 5.2?</p>

<p>Moreover, what is the minimum basic sanitation stuff we need in today?</p>
