求教一个include_once路径有关问题
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?
------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
------解决方案--------------------
3种都可以,但第一种如果出错最容易发现问题。
------解决方案--------------------
三种效果一样,这有什么纠结的?
------解决方案--------------------
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
