This is an illustration of how to send email through PHP. I did not create a function because I feel mail() is already a wrapper all by itself. I left the first parameter empty because I feel that the "to row" is not any more important than any other row in the header string

In the last article, the Phanatic was leading an expedition into a largely uncharted area. The conceptual project was a generalized form handler. The task's starting point was Matt Wright's famous "formmail" and included adding many more bells and whistles. While putting together the last tome, time and space were closing in on us, and in an effort not to strain the Phanatic's rapidly aging brain, we pulled into shore for a rest. Let's review the project's design goals before setting out to sea again.

I'll go over the simple passing of data from form to adding it to the database and the different functions and variables that can be used.

Let's get interactive with surfers again. I'd like to create a form mail system in PHP. First we need to create a form in HTML to gather the information. I am going to use one similar to my Perl form mailer script, because it looks clean.

The validation of data that has been entered in a form is necessary in most cases. Why is important? For example, what good is holding a contest or sweepstakes if you can't notify the winner, because he or she entered an invalid telephone number or an incorrect address. What good is having a mailing list if the e-mail addresses on it aren't verified, and your mailing list just bounces back to you without reaching the subscribers and target audience.Validating form entries saves you time and more importantly, it can save you money. And since somebody embossed the slogan "Time is money!", this should be very important for your web site!Well when should we validate? There are two types of validation; client side and server side.For reference, client side means that you are depending on what browser the user is currently using. On the client side, validation is performed using JavaScript. And that can be very tricky, because some users turn off JavaScript support in their browsers before they even come to your site. If you encounter of one those users, client side validation won't help you much if you try to verify data from a form because your JavaScript code will not be executed or interpreted by the browser, means you are back to square 1. Remember, the winner of your competition entered a wrong address.This is where server side validation comes in handy. It will always work, no matter what. Of course assuming that you have access to the technology on your server. Server side validation can be done with Perl, PHP, ASP, ColdFusion, JSP and almost any other scripting language. For this tutorial, I'll use PHP. A quite popular and easy to master server side scripting language.
