How to confirm php enabled on ubuntu server

On Debian (and thus Ubuntu), the Apache configuration files are stored under /etc/apache2. In that directory, there are 2 sub-directories for configuring modules: mods-available and mods-enabled. When you install an Apache module (ie: foo), it will put foo.load (and possibly foo.conf) into the /etc/apache2/mods-available directory. When you enable an Apache module using a2enmod, it will create a symbolic link in /etc/apache2/mods-enabled for each of the matching files from /etc/apache2/mods-available.

Thus for an Ubuntu server with PHP5 enabled, you should see something like this:

$ cd /etc/apache2
$ ls -l mods-*/*php*
-rw-r--r-- 1 root root 133 2008-02-27 15:49 mods-available/php5.conf
-rw-r--r-- 1 root root  59 2008-02-27 15:49 mods-available/php5.load
lrwxrwxrwx 1 root root  27 2009-02-05 07:30 mods-enabled/php5.conf -> ../mods-available/php5.conf
lrwxrwxrwx 1 root root  27 2009-02-05 07:30 mods-enabled/php5.load -> ../mods-available/php5.load

If the php5 configuration files aren't shown in the mods-enabled directory, enable them as follows:

$ ref="https://forum.tuteehub.com/tag/sudo">sudo a2enmod php5
$ ref="https://forum.tuteehub.com/tag/sudo">sudo /etc/init.d/apache2 restart

Once you've done that, in order to test that PHP5 is configured, create /var/www/test.php as follows:

$ echo "" | ref="https://forum.tuteehub.com/tag/sudo">sudo tee /var/www/test.php
$ ref="https://forum.tuteehub.com/tag/sudo">sudo chown www-data:www-data /var/www/test.php
$ ref="https://forum.tuteehub.com/tag/sudo">sudo chmod 755 /var/www/test.php

Once that's done, you should be able to browse to /test.php on that server and see the PHP configuration data.
