在php中使用带或不带括号的正确方法是什么 [英] What is the proper way to use include with or without brackets in php

问题描述

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.

解决方案

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
