PHP return if isset [duplicate]

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])

Answer 2

Consider using array_merge. Merging will overwrite keys of each given array allowing you to override an array of default values with the given values.

$defaults = array('some Key' => 'some Default Value');
$input = array('some Key' => 'a new value');
$merged = array_merge($defaults, $input);
$value = $merged['some Key'];

This won't work correctly for numeric keys however, so you should ensure you're working with an map instead of a vector.
