Deploy BotDetect PHP CAPTCHA Code Examples

After downloading and unpacking the BotDetect Captcha library, deploy examples by copying the entire extracted folder to your web server. Please note that all examples reference BotDetect CAPTCHA library by a relative path, and therefore cannot be deployed individually.

Choose the API You Wish to Use:

Note that those two APIs are like oil and water; they DO NOT mix at all -- use one or another!


Simple API (Experimental)

Since 2019/04/15 we are removing the Simple API docs from the tabs on the Traditional API docs' pages. That docs-cohabitation concept did not work -- neither for docs nor for the users :(.

Until we are done with that documentation reorganization please make sure that your Simple API integration efforts start with one of the following four step-by-step integration guides:

Those four guides listed above are updated and polished and should be reasonably bug-free in this moment. If you find a bug, or would like to propose an improvement, please let us know.

The rest of the Simple API docs on both the old and the new locations are a fairly outdated mess -- and should not be relied upon until further notice!

Traditional API

Until the 2019/04/15 the Traditional API docs' pages were forced to host the tabs with their unruly, ever-changing, but rarely up-to-date, experimental Simple API cousins.

It did not work; both us and the users were getting lost -- so we are kicking the Simple API docs out to a new, separate, branch of documentation.

However, we might need a week or two to clean up all the mess that such a cohabitation created. If you spot a bug in the Traditional API docs please let us know.
