$b = $a + $b;
}

myTest();
echo $b;
?>

PHP:



Run PHP on your own computer: The easiest way to do this is to install a complete package like XAMPP. This contains the Apache Web server, along with PHP and the MySQL database engine, in one easy-to-install package. XAMPP ( http://www.apachefriends.org/en/xampp-windows.html ) is available for Windows, Mac OS X, and Linux. (A popular alternative on Windows is WampServer [ http://www.wampserver.com/en/ ].)



Run your PHP scripts on your Web host: If you already have a Web hosting account that supports PHP then you can upload your PHP scripts via FTP and run them on the Web server. The advantage of this approach is that you don't have to install anything; the disadvantage is that it's slower to write and test your scripts.



Copy and paste the script code listed above into a new document in your text editor, then save the file as hello.php in the document root folder — that is, the top level of your website — on your hard drive. If you're not sure where your document root folder is then consult your Web server manual. Common locations include:

------------------------------------------------------------------------------

XAMPP on Windows: C:/xampp/htdocs/ (If you install it anywhere else, it WON'T WORK. Save your project in, say C:/xampp/htdocs/mycode/ , where you install "index.php"; Click on xampp-control icon, click "start apache", click "start mysql". Open browser and call php script: http://localhost/mycode/ in the address bar. "index.php" file will be parsed and shown in browser.)



XAMPP on Linux: /opt/lampp/htdocs/



If you want to run the script on your Web hosting account rather than your own computer then you'll need to upload the script using FTP instead.

To run a PHP script locally, you must have a webserver set up that will serve PHP pages. Try XAMPP:
