You can remove it directly. No.
However, in linux, you must specify php to execute the script.

Is this item still valid in linux? You have to ask Niu's moderator.

#! /Usr/bin/php
Specifies the software used to execute the code. of course, this file must be set to executable.
Equivalent
/Usr/bin/php filename. php

Windows does have this mechanism, but you have similar statements.
