获取PHP的问题包括使用不同文件夹中的文件 [英] Problem getting PHP include working with files in different folders

问题描述

我是一个完整的PHP菜鸟，我使用的是非常简单的PHP包括：

I'm a total PHP noob and am using a pretty simple PHP include:

<?php include("~head.php"); ?>

为网站做一些模板（为我的所有网站提供常见的页眉，页脚，菜单）页）。

to do a bit of templating for a website (to achieve common headers, footers, menus for all my pages).

• 注意：波形符（〜）只是为了让目录更易于查看（将主文件推送到顶部）按字母顺序排序的列表）

• NOTE: The tilde (~) is simply there to make the directories easier to look at (pushes main files to the top of the list when sorted alphabetically)

它适用于同一目录但我引用时的文件目录之外的文件，如下所示：

It's working great for files that are in the same directory but when I reference a file outside of a directory, like so:

<?php include("../~head.php"); ?>

然而，它似乎没有找到文件，因为标题显然没有被拉进入标记。

However, it simply doesn't seem to be finding the file as the header is clearly not being pulled into the markup.

相反，如果我用完整的网址引用该文件，例如

Conversely, if I reference the file with a full url, e.g.

<?php include("http://example.com/~head.php"); ?>

我的页面上出现以下错误代码。

I get the following error code on my page.

Warning: include() [function.include]: URL file-access is disabled in the server configuration in /home/content/65/7392565/html/bikini/angela_bikini.php on line 1

Warning: include(http://example.com/~head.php) [function.include]: failed to open stream: no suitable wrapper could be found in /home/content/65/7392565/html/products/product_a.php on line 1

Warning: include() [function.include]: Failed opening 'http://example.com/~head.php' for inclusion (include_path='.:/usr/local/php5/lib/php') in /home/content/65/7392565/html/products/product_a.php on line 1

奇怪的是，../ file.php语法适用于非头文件（例如我用于菜单的包含）。

Strangely, the "../file.php" syntax works for non-header files (e.g. the include I'm using for the menu).

因为这样的代码变得有点碎片，很难在所有不同的页面上维护变化。任何想法或解决方案将非常感谢。我真的是一个菜鸟，所以我可能无法绕过任何太过花哨的东西。 ：）

As such code's gotten to be a bit of a fragmented mess and is difficult to maintain changes across all the different pages. Any thoughts or solutions would be very much appreciated. I really am a noob tho so I probably won't be able to wrap my head around anything too fancy. : )

感谢您的时间。

推荐答案

不是仅使用 ../ 来获取上面的目录，这样的构造将创建完整的文件路径：

Rather than using only the ../ to get the directory above, a construct like this will create the full filepath:

// Assuming you are including from the root
$application_path = dirname(__FILE__);
include("$application_path/../header.php);

通常我' ll通过定义常量而不是使用变量来做到这一点。

Typically I'll do this by defining a constant, rather than using a variable.

define('APP_PATH', dirname(__FILE__));

将此用作：

// Assuming you are including at the file root:
define('APP_PATH', dirname(__FILE__));
include(APP_PATH . "/include/head.php");

// Assuming you are including from /include (one directory in)
// append a "/../" onto the end to indicate that the application
// root is one directory up from the currently executing file.
define('APP_PATH', dirname(__FILE__) . "/../");
include(APP_PATH . "somefile_at_the_root.php");
