php引述文件的方法
php引用文件的方法
转自： ?http://www.phpweblog.net/yemoo/archive/2007/09/29/2046.html? ? 引用文件的方法有两种：require 及 include。两种方式提供不同的使用弹性。 require?的使用方法如? include?使用方法如?require("MyRequireFile.php");?。这个函数通常放在 PHP 程序的最前面，PHP 程序在执行前，就会先读入 require 所指定引入的文件，使它变成 PHP 程序网页的一部份。常用的函数，亦可以这个方法将它引入网页中。include("MyIncludeFile.php");?。这个函数一般是放在流程控制的处理部分中。PHP 程序网页在读到 include 的文件时，才将它读进来。这种方式，可以把程序执行时的流程简单化。
