PHP include and related statements are not functions

[schlessera]

Issue Overview

The PHP include and related statements are not functions. They don't require parentheses, and adding them nevertheless just creates unnecessary extra processing.

Expected Behavior

Include statements should be used without parentheses:

include 'folder/some_file.php';

Current Behavior

The include statements use superfluous parentheses:

include( 'folder/some_file.php' );

Possible Solution

Parentheses should be removed on include statements.
