captcha.net look a like needed

Hello. What im looking for is a image captcha that has the same image type as [login to view URL] i dont need voice etc. Words should be picked from a array with words. It doesnt have to be fancy or anything. I just need php to print a image like the [login to view URL] one. Its not for a service like [login to view URL], its for my existent website. So i need a PHP script which prints a word on a image, distort it and a line through the word like on captcha.net. Best Regards Jawn
