A system PHP binary is specified in the scheduled task, while a higher version should be used to run the PHP script:
If the option Task type is set as Run a command and a PHP binary is specified as
php, the system PHP will be used to run the command.
If the option Task type is set as Run a PHP script, Plesk will use the system PHP to run the command.
Connect to a Plesk server via SSH.

Find a required PHP version and copy its path under the php-cli column. For example, if the PHP script requires the PHP version 5.6, the path will be
In Plesk go to Scheduled Tasks > Add Task:
Set the option Task type as Run a command.
