Load variables from external file in PHP
提问by Adrian M.
How can I import a variable from an external file? What I want to do is to have a configuration file in which I can write all my website settings and then to import these settings to every file, so I can set the website skin and things like that.
如何从外部文件导入变量？我想要做的是有一个配置文件，我可以在其中写入我所有的网站设置，然后将这些设置导入每个文件，这样我就可以设置网站皮肤和类似的东西。
How can I do this?

You can have a file with configuration and then include it on every script, like jeroen told you:
您可以拥有一个带有配置的文件，然后将其包含在每个脚本中，就像 jeroen 告诉您的那样：
config.inc.php
配置文件
$config['dbname'] = 'myDB';
$config['dbuser'] = 'user';
...
...
then in your scripts
然后在你的脚本中
include_once('config.inc.php');
You could also use inheritance where you have a model for example that uses the config and then you can extend that model class.
您还可以在您有一个模型的地方使用继承，例如使用配置，然后您可以扩展该模型类。

You can use auto_prepend_fileto prepend your settings in every PHP scripts that is executing. It's inside the php.ini, or you can use .htaccess(php_value auto_prepend_file "path/mysettings.php"), or using ini_set(). The file must be a valid or existing.
您可以使用auto_prepend_file在每个正在执行的 PHP 脚本中预先设置您的设置。它在 内php.ini，或者您可以使用.htaccess( php_value auto_prepend_file "path/mysettings.php") 或使用ini_set(). 该文件必须是有效的或存在的。

It depends on how you want to store your configuration. You can just include a php file that has stuff like:
这取决于您希望如何存储配置。您可以只包含一个包含以下内容的 php 文件：
$config['stuff'] = "value";
but you can also use a config (ini) file or a xml file. PHP has standard functions available to read config files or xml files, so that′s easy as well.
但您也可以使用配置 (ini) 文件或 xml 文件。PHP 具有可用于读取配置文件或 xml 文件的标准函数，因此也很容易。
