    Example #1 PNG creation with PHP

    <?php

    header("Content-type: image/png");
    $string $_GET['text'];
    $im     imagecreatefrompng("images/button1.png");
    $orange imagecolorallocate($im22021060);
    $px     = (imagesx($im) - 7.5 strlen($string)) / 2;
    imagestring($im3$px9$string$orange);
    imagepng($im);
    imagedestroy($im);

    ?>

    This example would be called from a page with a tag like:
    <img src=”button.php?text=text”>. The above
    button.php script then takes this
    “text” string and overlays it on top of a base image which
    in this case is “images/button1.png” and outputs the
    resulting image. This is a very convenient way to avoid having to
    draw new button images every time you want to change the text of a
    button. With this method they are dynamically generated.
