First off create a file called "phpinfo.php
", edit the file with good ol' notepad (if your under windows) or any simple text editor. Copy and paste this into the file...
Then upload it to your server, and call the file in your browser. "http://www.myserver.com/phpinfo.php
If the file runs and you get a long page of information, you have a PHP enabled server for one and right at the top it tells the version.
If your browser popups up a "Download this File" dialog box or it just shows you the code above, then you do not have a PHP enable server. or you dont have access.
