I'm on Centos7 i have enable multiple php versions with remi repo like :
yum-config-manager --enable remi-php56
yum-config-manager --enable remi-php71
yum-config-manager --enable remi-php72
yum-config-manager --enable remi-php73
Then installed the packages :
yum install php{version}
yum install php{version}-php-{extension}
I have setup PHP5.6 like :
sudo update-alternatives --set php /usr/bin/php56
When i make php-v :
PHP 5.6.40 (cli) (built: Sep 29 2020 11:38:05)
But when i'm going to my phpinfo() file i get PHP Version 7.3.23
In centos/RH we can't make :
sudo a2enmod php56
so i'm confusing and i don't know why httpd interpret version 7.3.23
How could i setup a PHP specific version to httpd?
You are confused by 2 set of packages:
See the repository FAQ.
If you want to install and run multiple versions, you have to use the SCLs and switch to FPM (instead of mod_php, this is the default way on CentOS 8).
In short, configure each FPM instance to run on a specific socket (network port or UDS), and configure Apache to use the proper version per virtual host, project, directory... using the SetHandler directive.
