This is a tiny function to read an array configiration file, and return the key in a dot notation
function config($key, $default = null) {
static $config = null;
// Is already read? No=>Read config
if ($config == null) {
$config = include __DIR__ . '/config.php';
}
$temp = $config;
$path = explode(".", $key);
foreach ($path as $key) {
if (isset($temp[$key])) {
$temp = $temp[$key];
continue;
}
return $default;
}
return $temp;
}
