Welcome to TakeTwo Apps: Email Contact Form

As a webmaster you most likely dont want to openly publish your email address on the web in order to avoid spam. If this is the case with you, then you need a form and some backend code to process the form data. This code example is a simple email contact form written in PHP and contains many security features. You can also download this code example here.
