If that is, the php scripts are executed with php 8.2 and when using exec() in a php script the exec is executed with php 7.2 and I want it to be executed also with php 8.2
On debian/ubuntu I would use update-alternatives to select which php `php` points to, no idea how that works in centos, worst case you'd have to manually overwrite /usr/bin/php with a symlink to your desired php binary.
