In Python one can do:

foo = {}
assert foo.get(\'bar\', \'baz\') == \'baz\'

In PHP one can go for a trinary operator as in:<

I find it useful to create a function like so:

function array_value($array, $key, $default_value = null) {
    return is_array($array) && array_key_exists($key, $array) ? $array[$key] : $default_value;
}

And use it like this:

$params = array('code' => 7777, 'name' => "Cloud Strife"); 

$code    = array_value($params, 'code');
$name    = array_value($params, 'name');
$weapon  = array_value($params, 'weapon', "Buster Sword");
$materia = array_value($params, 'materia');

echo "{ code: $code, name: $name, weapon: $weapon, materia: $materia }";

The default value in this case is null, but you may set it to whatever you need.

I hope it is useful.
