Why might the scheduler not run a script that works when accessed directly through the browser?

Question

ISPmanager

Ispmanager is installed on the server, configured the scheduler to run a specific script, rights 777, run once a minute - does not work. The "Fill" button in the scheduler panel in ispmanager (to check the script) runs the script but gives the following errors:
root# #_path_to_script_from_server_root_#
#_path_to_script_from_server_root_#: line 1: ?php: No such file or directory
#_path_to_script_from_server_root_#: line 2: syntax error near unexpected token `('
#_path_to_script_from_server_root_#: line 2: `$_SERVER["DOCUMENT_ROOT"] = realpath(dirname(__FILE__)."/../..");'
but if you access the script directly from the browser, everything will work without errors.What could be the problem?

Answer 1

because the script for the scheduler must have a different beginning
written in the very first line and then maybe already <?php
