Remove brackets from PHP statements

[grandeljay]

This PR changes some mentions of PHP statements which have brackets on them. It makes it looks like they are functions which they are clearly not. VS Code correctly describes them as statements. The tooltips should now reflect that too.

Sure, and I'm not a PHP expert but it seems common and idiomatic to include parens, even if they aren't required, right? Plus it seems that PHP includes them in error messages. If a require fails, I get Fatal error: require(): Failed opening required

That is a very good point. I was browsing the official PHP doc and I found some arguments for my PR:

• include

  Because include is a special language construct, parentheses are not needed around its argument.

• require

  Remember, when using require that it is a statement, not a function.

As you may know PHP is a heavily criticised programming language and often rightfully criticized. There are many quirks and inconsistencies. I'm willing to bet the error message you received (require() instead of require) is also incorrect.
