Salam Every body

I host this script in fatcow but it give me an "Internal Server Error".

Here are the script:

<?php 
    create_image(); 
    exit();

    function create_image() 
    {
        // Set the content-type

        // Create the image
        $im = imagecreatefrompng('coupon.png');
        // Create red color
        $red = imagecolorallocate($im, 120, 20, 20);
        //get font arail
        $font = 'font/arial.ttf';
        // Insert variables into coupon

        imagettftext($im, 36, 0, 176, 695, $red, $font, $_POST['Tdesc']);
        imagettftext($im, 36, 0, 176, 985, $red, $font, $_POST['Tclient']);
        imagettftext($im, 40, 0, 176, 1145, $red, $font, $_POST['Texpire']);
        imagettftext($im, 42, 0, 176, 1355, $red, $font, $_POST['Toffre']);

        imagettftext($im, 55, 0, 1796, 422, $red, $font, $_POST['Tcommande']);
        imagettftext($im, 36, 0, 1488, 1000, $red, $font, $_POST['Tadresse']);
        imagettftext($im, 36, 0, 1488, 1290, $red, $font, 'Tél. '. $_POST['Ttel']);
        imagettftext($im, 60, 0, 1488, 1590, $red, $font, $_POST['Tvaleur']);
        imagettftext($im, 60, 0, 1488, 1840, $red, $font, $_POST['Tcode']);

        // Using imagepng() results in clearer text compared with imagejpeg()
        imagepng($im);
        imagedestroy($im);  

    } 
?>

And the error message:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, and inform them of the time the error occurred, and anything you might have done that may have caused the error.

Easy to fix: - just reverse your definition and call;

<?php

    function create_image() 
    {
        // Set the content-type

        // Create the image
        $im = imagecreatefrompng('coupon.png');
        // Create red color
        $red = imagecolorallocate($im, 120, 20, 20);
        //get font arail
        $font = 'font/arial.ttf';
        // Insert variables into coupon

        imagettftext($im, 36, 0, 176, 695, $red, $font, $_POST['Tdesc']);
        imagettftext($im, 36, 0, 176, 985, $red, $font, $_POST['Tclient']);
        imagettftext($im, 40, 0, 176, 1145, $red, $font, $_POST['Texpire']);
        imagettftext($im, 42, 0, 176, 1355, $red, $font, $_POST['Toffre']);

        imagettftext($im, 55, 0, 1796, 422, $red, $font, $_POST['Tcommande']);
        imagettftext($im, 36, 0, 1488, 1000, $red, $font, $_POST['Tadresse']);
        imagettftext($im, 36, 0, 1488, 1290, $red, $font, 'Tél. '. $_POST['Ttel']);
        imagettftext($im, 60, 0, 1488, 1590, $red, $font, $_POST['Tvaleur']);
        imagettftext($im, 60, 0, 1488, 1840, $red, $font, $_POST['Tcode']);

        // Using imagepng() results in clearer text compared with imagejpeg()
        imagepng($im);
        imagedestroy($im);  

    } 

    create_image(); 
    exit();
?>

You should probably also add a header call to set the content type.

In the future if you have this kind of error you can also just add:

if (isset($_GET["debug"])){
    ini_set("display_errors", "1");
    error_reporting(E_ALL);
    }

to print out any errors - the if is optional; I have that on most of my files so I can just add ?debug to the url and instantly see the problem(s) if I make a typo or something.
