What is the proper way to use include with or without brackets in php

include, php, require

Solution

The `include 'sample.php';` or `require_once 'classes/DB.php';` is a preferred way.

Is preferred, it will prevent your peers from giving you a hard time and a trivial conversation about what require really is.

Reference.

Side Notes:

1. `require/include` not a function they are language construct same as `echo`. Credits: @Rahil comment.

2. Also it will save time of pressing two keystroke `(` & `)` for a lazy developers like us :p

Problem

I already know how to use `include`, `require` and even `require_once`. What I have always practiced is this: for example `include 'sample.php';` or `require_once 'classes/DB.php';` But in some ways I often see in some forums and tutorials and even here that they are using it like this - `include ('sample.php');` and `require_once ('classes/DB.php');`. I know that any of this will work, but I just want to know what would you recommend maybe as a good practice? XD and if it's already been asked here please show me the link because I can't find it.
