Question

I made this code that is supposed to show me an image with text on it, but the image just wont appear. Any idea?

<?php

    header("Content-type: image/png"); 
    $md5 = md5(microtime() * mktime()); 

    $string = substr($md5,0,5);

    $captcha = imagecreatefrompng('bg.png'); 

    $black = imagecolorallocate($captcha, 0, 0, 0); 
    $line = imagecolorallocate($captcha,233,239,239); 

    imageline($captcha,0,0,39,29,$line); 
    imageline($captcha,40,0,64,29,$line);

    imagestring($captcha, 5, 20, 10, $string, $black); 

    $_SESSION['key'] = md5($string); 

    imagepng($captcha);
    imagedestroy($captcha);

?>

Answer 1

You can not use mktime that way you would get the following error Strict standards: mktime() [function.mktime] which would not make your Image display

Replace

$md5 = md5(microtime() * mktime());

With

$md5 = md5(microtime() * time()); 

Your Output
