escapeshellarg() on urlencoded data
<p>I sent $data (array) from one server to another as shown below.  When it gets to the second server, the $data elements are obviously urlencoded.  On the second server, I wish to use some of the $data in exec().  Even though I pass a hash and make sure it is valid on the other end, I would still like to escapeshellarg() as appropriate.  Since the $data elements are already urlencoded, how should I apply escapeshellarg()?  Thanks </p>

<pre><code>curl_setopt($ch,CURLOPT_POSTFIELDS,flatten_GP_array($data));

function flatten_GP_array(array $var,$prefix = false)
{
    //Used for CURL routines when sending multi-dimential array
    $return = array();
    foreach($var as $idx =&gt; $value){
        if(is_scalar($value)){
            if($prefix){$return[$prefix.'['.$idx.']'] = urlencode($value);}
            else {$return[$idx] = urlencode($value);}
        }
        else {$return = array_merge($return,library::flatten_GP_array($value,$prefix ? $prefix.'['.$idx.']' : $idx));}
    }
    return $return;
}
</code></pre>
