Well if you *insist* on using GD - but I promise you, CSS is a better way to do this.

You will need to generate your string, spilt the string into an array of characters using the # character as a separator, then join your array in reverse order to a new (reversed) string.
You can then pass this string to the imagettftext function.

Of course, I am assuming you know how to use the GD functions, and that you have a suitable arabic font with corresponding Unicode characters.

Try this :

$myunicode="#4324#1221#1222#0133#0421#4219#1311";
// I made this string up - insert real unicode characters here
$mychararray=explode("#",$myunicode);
// Split into array of single unicode characters
$mychararray=array_reverse($mychararray);
// Reverse the array elements
$mynewunicode=join("#",$mychararray);
// Rejoin the elements with a # character
print("result so far :".$mynewunicode."<br>");
$mynewunicode="#".substr($mynewunicode,0,-1);
// Using join, there will be a trailing # and
// no required # at the start -- fix that
print($mynewunicode);

Then you can pass the $mynewunicode string to your TTF functions.

Hope that helps
