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.
How can I do this?
You can have a file with configuration and then include it on every script, like jeroen told you:
config.inc.php
$config['dbname'] = 'myDB';
$config['dbuser'] = 'user';
...
then in your scripts
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.
It depends on how you want to store your configuration. You can just include a php file that has stuff like:
$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.
You can use auto_prepend_file to 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.
