brent Posted October 31, 2023 Share Posted October 31, 2023 On your system, if you have installed multiple versions of PHP (eg PHP 7.1 and PHP 8.4). PHP 8.4 is running as default PHP for Apache and CLI. For some web applications may have a requirement, you need to use PHP 7.1. Then you don’t need to remove PHP 8.4. You can simply switch your PHP version to default used for Apache and command line. For example, your server has PHP 7.1 and PHP 8.4 both version’s installed. Now following example will help you to switch between both versions. From PHP 8.4 => PHP 7.1 Default PHP 5.6 is set on your system and you need to switch to PHP 7.1. Run the following commands to switch for Apache and command line. Apache:- $ sudo a2dismod php8.4 $ sudo a2enmod php7.1 $ sudo service apache2 restart Command Line:- $ sudo update-alternatives --set php /usr/bin/php7.1 $ sudo update-alternatives --set phar /usr/bin/phar7.1 $ sudo update-alternatives --set phar.phar /usr/bin/phar.phar7.1 From PHP 7.1 => PHP 8.4 Default PHP 7.1 is set on your system and you need to switch to PHP 5.6. Now run the following commands to switch for Apache and command line. Apache:- $ sudo a2dismod php7.1 $ sudo a2enmod php8.4 $ sudo service apache2 restart Command Line:- $ sudo update-alternatives --set php /usr/bin/php7.1 $ sudo update-alternatives --set phar /usr/bin/phar7.1 $ sudo update-alternatives --set phar.phar /usr/bin/phar.phar7.1 Link to comment Share on other sites More sharing options...
