Protect website against PHP Curl post method? -


OK, suppose we have a form that allows people to post their comments as you I know, "bad people" can easily spam me with the help of PHP curls. How can I protect my website with Captcha? Thank you.

The easiest way to use some form of captcha protection (reCAPTCHA) or posting comments to users They log in before (this can not really stop spamming, but it makes it easy to take action against spammers by blocking their account).

In addition to this you can take some simple preventive measures. Limit the number of comments that they can do within a set time frame - and will probably show only one captcha when they set the limits that they are human (like SO).

But I do not think the code is capable of changing the color of each variable declared....
