Global or include?

Say you have 10 or so scripts and a single config file. If you have main.php, functions1.php, functions2.php, functions3.php.. Does is hurt to do an include of the config file in each separate script, even if you only need a few things from it, or should you just specify what you want with a 'global' within each script/function?
