phpinfo() not working in apache2

Question

I wanted to install php5.3 on ubuntu 14.04(its not natively available as ubuntu pkg), so I installed each apache2, mysql5.6 and php5.3 separately.

PHP5.3 is utmost important for my project.

Now i wanted to test if each of them was working fine together.

I created a info.php file in /var/www/html/ containing code as <?php phpinfo(); ?> but the output showed an output like an HTML rendered page.

Can anyone please tell me how to test/check if all three of them are working together fine?

I would be very thankful, if anyone can please give a link or detailed-description where I can read instructions on how to integrate all three of them together while not uninstalling any of them.

Answer 1

Install sudo apt-get install libapache2-mod-php5 if you didnt before.

Answer 2

sudo apt-get install libapache2-mod-php5

This doesn't work because is obsolete:

sudo apt-get install libapache2-mod-php5

Reading package lists... Done Building dependency tree
Reading state information... Done Package libapache2-mod-php5 is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

E: Package 'libapache2-mod-php5' has no installation candidate

Answer 3

Equivalent solution for PHP 7: install libapache2-mod-php:

sudo apt install libapache2-mod-php
