What is PHP?

PHP is a server-side, cross-platform, HTML embedded scripting language. If you are completely new to PHP and want to get some idea of how it works, have a look at the ' . make_link("/tut.php", "introductory tutorial") . '. Once you get beyond that, have a look at the example archive sites and some of the other resources available in the ' . make_link("/links.php", "links section") . '.

So, How Much Does It Cost?

This may sound a little foreign to all you folks coming from a non-Unix background, but PHP doesn\'t cost anything. You can use it for commercial and/or non-commercial use all you want. You can give it to your friends, print it out and hang it on your wall or eat it for lunch. Welcome to the world of ' . make_link("http://www.opensource.org/", "Open Source") . ' software! Smile, be happy, the world is good. For the full legalese, see the ' . make_link("/license/", "official license") . '.

Looking for the box? Use the "search" feature, conveniently located in the top-right corner of every page. If you search for something in the function list (and it's a valid PHP function), you will be directed to the appropriate manual page. If the function doesn't exist, you'll get a list of all the PHP functions, and and option to do a site-wide search for your phrase. And don't forget to visit the page to add "quickref" functionality right into your web browser.
