EM Captcha – Visual PHP Captcha Class – 1.1 BETA

I decided to take another look at EM Captcha to see if there were any improvements I could quickly make.


Here is a change log from version 1.0 to 1.1:

  • Removed the IP address check (due to someone potentially having a different IP address when loading and then submitting the captcha form)
  • Made the code more efficient in several places
  • Made the code easier to read
  • Removed yellow as one of the possible captcha string colours
  • Fixed the expiry time option
  • Added question text option
  • Made the valid check case insensitive rather than case sensitive
