PHP Warning: include_once() Failed opening '' for inclusion (include_path='.;C:\xampp\php\PEAR')
提问by Bogdan Burym
I know this error is very common, I've tried to search google, I did the tricks to no avail. So my setup is, I have 3 directories:
我知道这个错误很常见，我试过在谷歌上搜索，但我的技巧无济于事。所以我的设置是，我有 3 个目录：
CLASSES->constants
PAGES
INITCONTROLS
类-> 常量
页面
INITCONTROLS
EDIT:I've got new error:
编辑：我有新的错误：
*Warning: require_once(initcontrols/config.php) [function.require-once]: failed to open stream: No such file or directory in*
*警告：require_once(initcontrols/config.php) [function.require-once]：无法打开流：没有这样的文件或目录*
below is my fragment of code:
下面是我的代码片段：
require_once("initcontrols/config.php");
<div>
<?php
$file = "initcontrols/header_myworks.php";
include_once($file);
echo $plHeader;?>
</div>
What is still lacking in here? Thanks for all help in advance.
这里还缺少什么？提前感谢所有帮助。

This should work if current file is located in same directory where initcontrolsis:
如果当前文件位于initcontrols所在的同一目录中，这应该可以工作：
<?php
$ds = DIRECTORY_SEPARATOR;
$base_dir = realpath(dirname(__FILE__) . $ds . '..') . $ds;
require_once("{$base_dir}initcontrols{$ds}config.php");
?>
<div>
<?php
$file = "{$base_dir}initcontrols{$ds}header_myworks.php";
include_once($file);
echo $plHeader;?>
</div>

The include path is set against the server configuration (PHP.ini) but the include path you specify is relative to that path so in your case the include path is (actual path in windows):
包含路径是针对服务器配置 ( PHP.ini) 设置的，但您指定的包含路径是相对于该路径的，因此在您的情况下，包含路径是（Windows 中的实际路径）：
C:\xampp\php\PEAR\initcontrols\header_myworks.php
providing the path you pasted in the subject is correct. Make sure your file is located there.
提供您在主题中粘贴的路径是正确的。确保您的文件位于那里。
For more info you can getand setthe include path programmatically.

It is because you use a relative path.
这是因为您使用了相对路径。
The easy way to fix this is by using the __DIR__magic constant, like:
解决此问题的简单方法是使用__DIR__魔术常量，例如：
require_once(__DIR__."/initcontrols/config.php");
From the PHP doc:
来自 PHP 文档：
The directory of the file. If used inside an include, the directory of the included file is returned
文件的目录。如果在包含中使用，则返回包含文件的目录

Put in config.php this
把这个放在config.php
$config['rewrite_short_tags'] = FALSE;
