Arabic Glyphs to Render Arabic Text:

Takes Arabic text as an input and performs Arabic glyph joining on it and outputs a UTF-8 hexadecimals stream that is no longer logically arranged but in a visual order which gives readable results when formatted with a simple Unicode rendering just like GD and PDF libraries that does not handle basic connecting glyphs of Arabic language yet but simply outputs all stand alone glyphs in left-to-right order.

Example Output:

Example Code:

<?php
    // Create the image
    $im = @imagecreatefromgif('images/bg.gif');

    // Create some colors
    $black = imagecolorallocate($im, 0, 0, 0);
    $blue  = imagecolorallocate($im, 0, 0, 255);
    $white = imagecolorallocate($im, 255, 255, 255);

    // Replace by your own font full path and name
    $path = substr(
        $_SERVER['SCRIPT_FILENAME'], 0, 
        strrpos($_SERVER['SCRIPT_FILENAME'], '/')
    );
    $font = $path.'/fonts/Amiri-Regular.ttf';

    // UTF-8 charset
    $text = 'بسم الله الرحمن الرحيم';
    imagefill($im, 0, 0, $white);
    imagettftext($im, 20, 0, 10, 50, $blue, $font, 'UTF-8:');
    imagettftext($im, 20, 0, 250, 50, $black, $font, $text);
