Can't open PHP files in Firefox (Apache installed)

[tonyr1988]

I've got the entire LAMP configuration installed, and this used to work. Apparently it doesn't anymore.

I threw my project in /var/www/folder-name, and the permissions should be set correctly (I made everything in there, including the folder, 777 to check).

I navigate to localhost, and I see "Index of /" with "Apache/2.2.8 (Ubuntu) Server at localhost Port 80" along the bottom. I see the folder. When I click on the folder, Firefox pops up with:

You have chosen to open:

which is a PHTML file.
What would you like to do?

(yeah, the name is blank)

If I navigate directly to localhost/folder-name/index.php, it gives me a similar message:

You have chosen to open:
index.php
which is a PHP file.

I restarted Apache (sudo /etc/init.d/apache2 restart) and it seems to be working fine (otherwise it wouldn't even give me the index page, right?).

What else should I check to see if everything is working properly?

Did you try clearing your browser cache after restarting apache? I doubt it will make a difference but worth a try. I have seen someone say this fixed there problem with this before.

look like your Apache doesn't know how to handle .php file. You can try to reinstall libapache2-mod-php5 package again, see if it can reset the configuration of Apache.

The permission seems to be OK.

I had once this problem too and after I restarted apache everything works like a charm.

Clearing the cache worked for me. I had messed with my php.ini file in lampp, and then had this problem with opening a phtml file. Neither restarting lampp nor rebooting helped. Clearing Firefox's cache did the trick.

Wow, this is weird, but its true. Restarting the cache in firefox did the trick for me. Glad i found this post or im sure i would have stayed up trying to fix this one.
