求教一个include_once路径问题
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.
