And if null is considered as a valid value and the value is deep inside the
array...
$d = isset($array['a']['b']['c']) && array_key_exists('d',
$array['a']['b']['c']) ? $array['a']['b']['c']['d'] : 'default';
or just
array_get($array, ['a', 'b', 'c', 'd'], 'default');

In the case you have those keys in a variable like $keys = ['key1', 'key2'] you
can access it only using a loop. That's one of the purpose of the function.
BTW what looks better and what is more readable?
$a = isset($array['a']) ? $array['a'] : null;
$b = array_key_exists('b', $array) ? $array['b'] : 'default';
or
$a = array_get($array, 'a');
$b = array_get($array, 'b', 'default');
?

@niki
Arg right. But still should not be added, zero value added here.

@Pierre:
isset($array['key1']['key2']) ?: NULL
is the same as
isset($array['key1']['key2']) ? isset($array['key1']['key2']) : NULL
is the same as "true" if the key exists, "null" if it doesn't.
That's not what this req is about.

$val = isset($array['key1']['key2']) ?: NULL;
We already have an operator for that ($v = (iftrue) ?: defaultvalue).
Operators are also much more efficient than a function call.

fl at nyggen dot com: I know this is possible. But i don't like suppressing
warning in this situation. And
@$array['key1']['key2'] ?: 'Key not found'
And the valid value could be false/0/""/"0"/[].
