@ Barry
Hi there Barry! Just downloaded your captcha, and it appears to be working absolutely perfectly now! Brilliant work!
Let me know if you need any help with the code in the future!

@ Barry
Definitely will download your captcha, and quickly wire it up for you! I'll email it to the address you used to make the comments on this blog, but let me know if you want it sent somewhere else.
@ Ted
Unfortunately, str_split() is only available in PHP version 5 and up, but you can easily write your own function which will have the same effect. Put the code below at the top of your file:
<?php
if(!function_exists('str_split'))
{
function str_split($string, $split_length = 1)
{
if(strlen($string) > $split_length || !$split_length)
{
do
{
$c = strlen($string);
$parts[] = substr($string, 0, $split_length);
$string = substr($string, $split_length);
}
while($string !== false);
}
else
{
$parts = array($string);
}
return $parts;
}
}
?>
And that should do the trick! Let me know though if you need some more help. =]

I get this error:
Fatal error: Call to undefined function: str_split() in /home/acroplex/public_html/main_captcha.php on line 76
$captcha_code_array = str_split($captcha_code);
Any ideas?

Check out part one of this article, where I show you how you can create the function in this article that we use to create a captcha image. Now that we have a basic function which we use to generate a captcha question and answer, we're now going to spin a bit of PHP magic, and turn the question into an image so it's harder for bots and computers to parse the text and calculate the answer themselves. To get this working, you need to create two files. The first one is going to contain the code which will generate...
2 Free Santa Hat Photoshop Vectors by Nathan

I spent a while at the start of this month looking for some little Santa hat vectors to put atop the unfinity design logo, but to absolutely no avail! To my surprise, I couldn't find but one free Santa hat vector anywhere, let alone non-vector. In the face of the evil tyranny that is paying for things, I made my own, and thought it'd only be right to share. You can use these vectors how you want in any project you so desire. A link back here is optional. They're pretty terrible in my opinion right now, but I generally lack...

In this post, you'll find 10 fantastic and free WordPress themes that you can use on your website. There's all sorts of styles to choose from, some elegant and some funky, but all are completely zilch to pay.

Check out part two of this article, where I show you how you can use the function in this article to create a captcha image. I've had this code lying around for a while now, and I thought it was only right to share it! After all, sharing is caring! It's free to use, personal or commercial, and all I ask for is a comment to let me know what exciting projects you're going to use it in! A link back is optional. ;] It's a simple mathematical question based captcha written in PHP, and you can see a working...

Icons are powerful little things. In just a few meagre pixels, they can tell your users exactly what the function of an interactive element is, and do it more efficiently than any other image or textual device. Icons provide context in a beautiful way, and help designers use space in a functional and practical sense. They were first used in the 70's as a way to make computer interfaces more usable, and were popularised by the Apple Macintosh and Microsoft Windows operating environments, who began to rely heavily on the use of graphic notations in their user interface. As web designers...

Blog Action Day is a day where bloggers around the world unite to discuss one ever growing, ever important global issue. This year, it's poverty. Poverty affects millions of people around the globe. It's not just in third world countries such as Africa that impoverished children and adults go without food for days, without shelter or fresh water. It is also an issue in more developed countries such as our own. Poverty should be the reason why billions of us that live life to the fullest shouldn't be able to sleep at night. But it isn't. Slowly, with poverty becoming such a...

You may be wondering why on earth I'm blogging about animal noises, but it's true, I rediscovered Moo the other day! No, in all seriousness, Moo is an online printing service that allows you to design and publish custom made business cards, swatch cards, greeting cards, and all sorts of other goodies. As you may notice in the picture above, I went for the business card avenue, and I can honestly say that I have never had a batch done that is of the quality the Moo ones are. The ink is firmly fasted to the paper, and the card that it...
