如何包括另一个PHP文件? [英] how to include another php file?

问题描述

我有一个php文件，我想包含另一个具有css链接标签和javascript源标签的php文件，但是当我尝试包含它们时，它并没有添加到页面中.

I have a php file, and I want to include another php file that have css link tags and javascript source tags, but when I try to include them, it doesn't get added to the page.

我的php页面:

<?php 
    $root = $_SERVER['SERVER_NAME'] . '/mysite'; 
    $theme = $root . '/includes/php/common.php';
    echo $theme;
    include($theme);
?>

common.php:

common.php:

<link rel='stylesheet' type='text/css' href='../css/main.css'/>";

有人知道怎么了吗?谢谢

Anyone know whats wrong? Thanks

推荐答案

PHP的 include 是服务器端的，因此您需要使用服务器端的路径.最好使用dirname(__FILE__)代替$_SERVER['SSCRIPT_NAME']，但是$_SERVER['SERVER_NAME']绝对错误.

PHP's include is server-side, so you need to use the server side path. It is better to use dirname(__FILE__) instead of $_SERVER['SSCRIPT_NAME'], but $_SERVER['SERVER_NAME'] is absolutely wrong.

尝试:

include dirname(__FILE__)."/common.php";

或者，如果要包含的文件不在同一目录中，请更改路径.例如，对于父目录，请使用dirname(__FILE__)."/../common.php".

Or if the file you want to include is not on the same directory, change the path. For example for a parent directory, use dirname(__FILE__)."/../common.php".

请注意，有些人可能建议使用include "./common.php"或类似名称.此可以起作用，但是当调用include的脚本实际上已被另一个目录中的另一个脚本包含时，很可能会失败.使用dirname(__FILE__)."/common.php"可以消除此问题.

Note that some might suggest using include "./common.php" or similar. This could work, but will most likely fail when the script invoking include is actually being included by another script in another directory. Using dirname(__FILE__)."/common.php" will eliminate this problem.
