In my last projects I'm using something I think is useful and it's not a common practice in our PHP projects. That's is the usage of a plain PHP's class for the application's configuration. Let me explain it. Normally we use ini file for configuration. [...] There are many standard options. Why I prefer a different one then? I like plain PHP classes because the IDE helps me with autocompletion. The usage is quite simple.

His example uses a standard class to store the configuration values, one that can be loaded into a project and lets you call the configuration values statically. He gives two examples of how this is helpful in a standard IDE with autocompletion.

When doing complex applications it's often nice to have some sort of system for handling settings. PHP has a nice function called parse_ini_file which can be used to create a basic but still usable setting file feature. A simple class which loads the configuration file and offers some methods to retrieve the values for a given key is all that's needed.

His example code gives a sample ini file with database connection information and a MyConfigClass that parses the file and can get or set values in it.
