include() 或 require() 函数,您可以在服务器执行 PHP 文件之前在该文件中插入一个文件的内容,除了它们处理错误的方式不同之外,这两个函数在其他方面都是相同的.
include() 或 require() 函数,您可以在服务器执行 php 文件之前在该文件中插入一个文件的内容,除了它们处理错误的方式不同之外,这两个函数在其他方面都是相同的,include() 函数会生成一个警告(但是脚本会继续执行),而 require() 函数会生成一个致命错误(fatal error)(在错误发生后脚本会停止执行).
<html>
<body>
<?php include("header.php");
<h1 id="welcome-nbsp-to-nbsp-my-nbsp-home-nbsp-page">welcome to my home page</h1>
<p>some text</p>
</body>
</html>三个文件，"default.php"、"about.php" 以及 "contact.php" 都引用了 "menu.php" 文件,这是 "default.php" 中的代码:
<?php include("menu.php");
<h1 id="welcome-nbsp-to-nbsp-my-nbsp-home-nbsp-page">welcome to my home page</h1>
<p>some text</p>
</body>
</html>require() 函数
require() 函数与 include() 相同,不同的是它对错误的处理方式.
include() 函数会生成一个警告(但是脚本会继续执行),而 require() 函数会生成一个致命错误(fatal error)(在错误发生后脚本会停止执行).
如果在您通过 include() 引用文件时发生了错误,会得到类似下面这样的错误消息:
<html>
<body>
<?php
include("wrongfile.php");
echo "hello world!";
</body>
</html>错误消息:
warning: include(wrongfile.php) [function.include]: failed to open stream: no such file or directory in c:homewebsitetest.php on line 5 warning: include() [function.include]: failed opening 'wrongfile.php' for inclusion (include_path='.;c:php5pear') in c:homewebsitetest.php on line 5 hello world!
