文件里面2个文件:
a.php
b.php

b页面内容:
1. include_once(dirname(__FILE__).'/a.php');
2. include_once('./a.php');
3. include_once(a.php');
该用哪种方式调用呢?


回复讨论(解决方案)

最简洁的是 3,当然需要 include_path 中有 . 这一项
1 最严密,也最麻烦最低效

3种都可以,但第一种如果出错最容易发现问题。

三种效果一样,这有什么纠结的?

还可以用完整路径  include_once '/var/www/html/a.php';  这样不用为多文件嵌套路径报错而烦恼了

还可以用完整路径  include_once '/var/www/html/a.php';  这样不用为多文件嵌套路径报错而烦恼了

还可以用完整路径  include_once '/var/www/html/a.php';  这样不用为多文件嵌套路径报错而烦恼了

3. include_once(a.php');  

显然写错了.... 

include_once('a.php');

更多时候我会写成

1 OR 2  这个看个人的习惯吧.
