Any more concise way to set default values?

Is there a built-in php function like the following:

function isset_get($array, $key, $default = null) {
    return isset($array[$key]) ? $array[$key] : $default;
}

I don’t like

$my_var = isset($my_array['some Key']) ? $my_array['some Key'] : '';

and would prefer

$my_var = isset_get($my_array, 'some Key', '');

or something similar…

Answer 1

No. In my codebase we have several helpers of this nature. The names are pretty terrible but since they are frequently used, concision is warranted

idx($array, $key, $default)
returns the $default if !isset($array[$key])

adx($array, $key, $default)
like idx, but enforces that $array is actually an array and throws if not.

edx($array, $key, $default)
returns the $default if !isset($array[$key]) or empty($array[$key])
