在PHP中包含文件时，哪种语法更好？ [重复]

Question

This question already has an answer here:

• Is php's 'include' a function or a statement? 9 answers

Some people include files like this:

include ('file.php');

and some people include files like this:

include 'file.php';

I think here the use of brackets is completely unnecessary. What are your views? Which style is better and why?

</div>

Answer 1

When brackets are unnecessary, it's better to remove them (Same for the return instead of return () which give better performances). Probably the same for includes.

http://php.net/manual/en/function.return.php

Note: Note that since return is a language construct and not a function, the parentheses surrounding its arguments are not required. It is common to leave them out, and you actually should do so as PHP has less work to do in this case.

Moreoever, using whole path for your include is better than just relative.
