PATH_SEPARATOR是什么_PHP教程

zendframework include 设置 index.php

set_include_path(. . PATH_SEPARATOR . ../library/ . PATH_SEPARATOR . ./application/models/

. PATH_SEPARATOR . ./application/lib/

. PATH_SEPARATOR . get_include_path());

PATH_SEPARATOR是一个常量，在Linux系统中是一个" : "号,Windows上是一个";"号。所以编写程序时最好用常量 PATH_SEPARATOR 代替，否则如果系统从linux移植到win系统或反过来移植会出错！
get_include_path取得当前已有的环境变量,加上前面的设置就是新的系统include
