Fastest way to store easily editable config data in PHP?

Question

What is the fastest way to store config data in PHP so that it is easily changeable (via PHP)? First I thought about having config.php file, but I can\'t edit it on fly with

Answer 1

I use a database with a table called config or settings. The table has two columns:

name [varchar(255)]
value [varchar(255)]

This allows the easy storage of int's, float's, and short strings.

Then I create two functions, GetSetting and SetSetting. These store a row and retrieve a row, respectively. I find that this simplifies the storing of values tremendously.
