Could you point how to solve this PHP versions conflict?

Hi Experts

Could you point how to solve this PHP versions conflict?

I guess it's preventing PHP pages to be renderized.

xxe@xxe-Inspiron-1525:/etc/apache2$ ls -l mods-*/*php*
-rw-r--r-- 1 root root 855 mar 14 19:30 mods-available/php7.1.conf
-rw-r--r-- 1 root root 102 mar 14 19:30 mods-available/php7.1.load
-rw-r--r-- 1 root root 855 mai  9 14:21 mods-available/php7.2.conf
-rw-r--r-- 1 root root 102 mai  9 14:21 mods-available/php7.2.load

HTML pages are renderized by Apache, not PHP pages.

Thanks in advance!

Eduardo,

it's often a php version conflict, could you please tell us which php version are you using ?
Eduardo FuerteDeveloper and AnalystAuthor Commented:
Well

Accordingly with my own question:

The versions installed are pointed at the question.
PHP  doesn't works out.
That it's a version conflict I had concluded and pointed at the question.
Ayoub RouziEntrepreneur & Web developerCommented:
The output of php -v will give you what is your default version.

Use following commands to view if you have any traces:

cd /etc/apache2/mods-enabled
ls -la

Open in new window


We suppose we want to upgrade From PHP 5.6 to PHP 7.1: (which the console tell you that you need some modules for.

If so then use following commands:

sudo a2dismod php5.6
sudo rm php5*

Open in new window


Now add the php7.1.conf and php7.1.load instead:

sudo a2enmod php7.1
sudo update-alternatives --set php /usr/bin/php7.1
sudo ln -s php7.1.conf ../mods-available/php7.1.conf
sudo ln -s php7.1.load ../mods-available/php7.1.load
sudo service apache2 restart

Open in new window


UPDATE: Replace 5.6 with the php version that you have (result of :
cd /etc/apache2/mods-enabled
ls -la

Open in new window
