get_include_path ()的有关问题
get_include_path ()的问题
请问get_include_path()到底是获取哪里的路径
我 echo get_include_path() ; //为什么输出会是 C:\php\pear
因为我经常看到 set_include_path ( get_include_path () . PATH_SEPARATOR . $path);
却不知道为什么里面要加 get_include_path() 这个函数 而不是直接写成如下
set_include_path ($path);
其实最主要是 我不明白 get_include_path() ;的涵意
------解决方案--------------------
include_path php 搜索路径
get_include_path() 返回的是当前 include_path 的值
通常就是 php.ini 中 include_path 的值
PATH_SEPARATOR include_path 分节符：windows ; linux :
set_include_path 设置 include_path
如不附加 get_include_path() 也是可以的，只是范围不同而已。不过也别抱怨：原来可运行的程序不能用了
------解决方案--------------------
set_include_path ( get_include_path () . PATH_SEPARATOR . $path);
这样写之后，再include文件，路径是相对与上面的，不用写绝对路径，也方便更改路径，
