PHP Captcha development questions...
Is it futile to make a captcha using php if i'm not going to utilize GD or imagemagick or some other server-side image processor to hide the captcha and give noise around it?
and how would one make a relatively safe and bot-free method of confirming a human is posting something?
Can I make any sort of legit captcha without sessions?
