I'm looking to store some basic information (just simple variables, not a database) which doesn't require any security (simple strings stored for case sensitivity, lets me skip a MySQL query to improve performance). I'm looking for quickest way to read the contents and create a few variables from those contents. I'm comfortable with how to interact with flat files for the most part, what I want to do is determine the most efficient way of storing a few variables and interpreting back in to PHP please.
PHP I'll store in the flatfile...
$case = 'My Site Name CaSiNG';
$string2 = 'some text';
