我有一个网站，根文件夹中包含 index.php ，图像位于 /img 中，overview.php 位于 /content< /代码>。我有一个 sidebar.php 文件，它包含在 index.php 和 overview.php 中。如果我在每个文件中包含链接，我应该如何引用 /img/image.gif？
image.gif 的位置相对于引用它的文件的位置发生变化。
在 sidebar.php 中使用 /img/image.gif 将在 index.php 中工作，但对于位于 的文件则失败/content/overview.php.
我能看到的唯一解决方案是在每个子目录中包含一个单独的 sidebar.php ，或者在每个子目录中包含一个 /img 目录。
我能找到的最好的建议是使用 >这里建议的 HTML 标签：
更改 PHP 中包含内容的相对链接路径< /a>
然而，在同一个链接中，SamGoody 建议 > 自版本 7 起，Internet Explorer 不再正确支持 标记。
在采取行动之前，我希望对此事有一些了解。
谢谢。
编辑：我使用下面的错误方法 "../"
示例 -
root/index.php:
...
<link rel="stylesheet" type="text/css" href="style.css" />
<title>title</title>
</head>
<body>
<?php include('include/header.php'); ?>
<?php include('include/menu.php'); ?>
...
root/include/header.php:
...
<div id="header">
<span class="fl"><img src="img/dun1.png"/></span><span class="fr"><img src="img/dun2.png"/></span>
...
root/content/overview.php:
...
<link rel="stylesheet" type="text/css" href="../style.css" media="screen" />
<title>Overview</title>
</head>
<body>
<?php include('../include/header.php'); ?>
<?php include('../include/menu.php'); ?>
...
I have a site with index.php in the root folder, images in /img , and overview.php in /content. I have a sidebar.php file that is included in both index.php and overview.php. How should I refer to /img/image.gif if I include a link in each file?
The location of image.gif changes relative to the location of the file that references it.
Using /img/image.gif in sidebar.php will work in index.php, but it fails for the file located at /content/overview.php.
The only solution that I can see is to either include a separate sidebar.php in each sub-directory, or include an /img directory in every sub-directory.
The best suggestion that I can find is to use the <base> HTML tag as suggested here:
Change relative link paths for included content in PHP
However, in the same link, SamGoody suggests that the <base> tag is no longer properly supported in Internet Explorer, since version 7.
I'd like some insight on the matter before committing to a course of action.
Thanks.
EDIT: I am using the wrong approach below with "../"
Example-
root/index.php:
...
<link rel="stylesheet" type="text/css" href="style.css" />
<title>title</title>
</head>
<body>
<?php include('include/header.php'); ?>
<?php include('include/menu.php'); ?>
...
root/include/header.php:
...
<div id="header">
<span class="fl"><img src="img/dun1.png"/></span><span class="fr"><img src="img/dun2.png"/></span>
...
root/content/overview.php:
...
<link rel="stylesheet" type="text/css" href="../style.css" media="screen" />
<title>Overview</title>
</head>
<body>
<?php include('../include/header.php'); ?>
<?php include('../include/menu.php'); ?>

但它不应该。前面的
/使其成为绝对路径，可以从服务器上的任何位置工作。如果这对您不起作用，则说明某处存在问题 - 在这种情况下，请发布一些示例。除非您计划有一天将整个站点移动到子目录中，或将图像移动到内容交付网络（这两种操作都需要重写地址），否则您可以安全地使用绝对 URL。
But it shouldn't. The preceding
/makes it an absolute path which will work from any point on the server. If this doesn't work for you, there's a problem somewhere - in that case, post some examples.Unless you are planning to move the whole site into a sub-directory one day, or move images to a Content Delivery Network (both actions would require re-writing the addresses) you can safely use absolute URLs.
