Stop using `global` in PHP

Question

I have a config.php that is included to each page. In config I create an array that looks something like:

$config = array();
$config[\'site_name\         


        

Answer 1

I've solved this with a class:

class Config
{
    public static $SiteName = 'My Cool Site';
}

function SomeFunction
{
    echo 'Welcome to ' , Config::$SiteName;
}

fcortes' suggestion to use constants is also a good one. I'd only like to suggest to give all constants a prefix, like CFG_SITE_NAME, so to avoid accidental name clashes with other constants.
