switch php version explanation

This script accept one argument, the expected php version.
In my case, i've placed this bash script under my home directory and made alias

> alias bash_file_location_which_change_php_version="/home/devnet/mine/bash/change_php_version.sh"

> alias php56="bash_file_location_which_change_php_version 5.6"

> alias php74="bash_file_location_which_change_php_version 7.4"

> alias php8="bash_file_location_which_change_php_version 8.0"

#### If i want to change the php version, all i need to do press php56 or php74 or php8 and i'm done.
