Load variables from external file in PHP
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.
