I am working on a project and I am in a need of a PHP captcha bypasser, if there is such a thing.

I know PHP has various image functions, but I don't know where to begin.

Of course, it would be much easier to send a get/post request to an external source such as a website and provide the dynamic image URL to solve it but I don't want to depend on services such as captchakiller. Besides, I don't want to pay for that service either.

If anyone knows any captcha-solving websites or perhaps some PHP functions that could "compare" images, deformed images, including tolerance, etc.

Any suggestions would be appreciated.

Sorry, but there is no DecodeCaptcha function in PHP so far :)
If it's a really easy captcha, you can just do it pixel-by-pixel using GD lib. You can also take a look at PHP OCR Class (somewhere on phpclasses.org).

If it's google captcha or recaptcha(however this one can be broken with success rate of about 15%), decaptcher would be best solution.
 
I've had mediocre success while experimenting with imagemagik + gocr (on lesser captchas that is...) Google and recaptcha? fgetaboutit...
 
if you dont already know where to start, dont attempt this, imagick+gocr with php however will get you a really good success rate once you know what you are doing and your not looking for bypass your looking for breaker
 
Acutally, I'm working on a pascal version and I'm pretty sure I'll get the easy ones working with no problem.
 
look on odesk my friend is expert php programmer he might be abe to hep you look up jacob pune that is his name on odesk
 
better off using human captcha service, $7 1000 images they have very simple api, i just implemented two such services in my own app
 
decaptcher does 1000 for $2 so it can get even cheaper. unless you want to invest time and money into your own captcha breaker, I'd go with someone else's for a small fee.
