Change PHP Standard CLI Version

This article explains how to change the default PHP CLI binary for an SSH user (system user). Please make sure that you use the shell /bin/bash for the system user.

Change PHP CLI version

First log in via SSH with the relevant SSH user (system user). You can then use the following command to change the default PHP version:

echo "export PATH=/opt/plesk/php/8.2/bin:$PATH;" >> ~/.bash_profile

source ~/.bash_profile

You can use the command php -v to check whether the changes have been applied correctly.

ssh_demo@s13311:~$ php -v

For example, to use PHP 8.1 as the default binary, you can use the command from step 2 as follows:

``bash echo "export PATH=/opt/plesk/php/8.1/bin:$PATH;" >> ~/.bash_profile

php -v

## Common errors

Error message:

/usr/bin/env: "php": File or directory not found

This error occurs if no standard PHP CLI version has been selected. In this case, you can either store the default CLI version or call the PHP binary directly. Example:

/opt/plesk/php/8.1/bin/php [your command]
