How to make quick judgement and assignment without isset()?

Question

I am tired of using code like:

$blog = isset($_GET[\'blog\']) ? $_GET[\'blog\'] : \'default\';

but I can\'t use:

$blog = $_

You can just write a custom helper:

function get($name, $default=null){
    return isset($_GET[$name]) ? $_GET[$name] : $default;
}

$blog = get('blog', 'default');

Alternatively, you have the filter extension, e.g.:

$blog = filter_input(INPUT_GET, 'blog') ?: 'default';

It's not noticeably shorter but allows further validation and sanitisation (and it's also trivial to wrap in a custom function).
