php with firefox
 

I have suse 12.2 and cannot work without php on firefox. How do I get firefox to recognize php? Any help would be appreciated.

Browsers (firefox, IE, Safari, Opera, ...) don't know anything about PHP - they cannot interpret it. It's what lies inbetween (apache, some framework...) that translates PHP into something that the browser can understand (html, javascript, ...).

php is in fact a server-side language, which means you need a web server, such as a pache
the web server i'm most familiar with is
you have to install apache, and php than configure a 'document root' for apache, put your php scripts in a folder under that, then brows to 'localhost/folder/phpscript.php'
