I have Ubuntu x64. I've already installed XAMPP and it's working fine with NetBeans.
I wanted to use Aptana 3, so I downloaded and uncompressed it, and clicked on "aptanastudio3". The program started fine, so I made a PHP file, and now I have no idea what to do; the run button gets me "external tools configuration".
I googled and found Setting up your web browser configuration, but the above link seems to be for version 2, and I'm using version 3.
How do I run a simple PHP file, or setup the external tools configuration so when I press run it works?
