How to improve captcha.php
Date: 01/27/08
(PHP Community) Keywords: php, html
A couple of things:
1) Every so often captcha.php results in a blank image with no text. It occurs very rarely and randomly. How can I prevent this?
2) I will have multiple programs using this very same PHP to produce what should be different captcha images. Like you will have emailalert.php calling an HTML img src tag pointing to captcha.php, but so will guestbook.php, trivia,php, profile.php, etc. How can I accomplish this?
Thanks
