text1 / text2 to array ['text1'] ['text2']？

Question

I'm trying to make something like

function config( $string ){
    require 'configuration.php';
    return $config[$string];
}

but i have a problem when my config has a 2D array. like:

$config['features'] = array(
        'memcached' => TRUE,
        'compress'  => TRUE,
        'gzip'      => TRUE
);

how can i get config('features/memcached') or if can we have three or more threaded array like config('features/memcached/version14/etc') ( example ) to return true but still works when we do something like config('features') returns the array just like the function above. any ideas ?

Answer 1

Just split the string into keys:

function config( $string ){
    require 'configuration.php';
    $keys = explode('/',$string);
    $return = $config;
    foreach($keys as $key){
        $return = $return[$key];
    }
    return $return;
}

Here you can do this too:

config('features/others/foo/bar');

if this exists:

$config['features'] = array(
    'memcached' => TRUE,
    'others'  => array( 'foo' => array( 'bar' => 42 ) )
);
