Quickest way to assign a PHP variable from an array value that may not exist without error

This has been bothering PHP developers for years and in PHP 7 the COALESCE operator ?? finally arrived:

The new way (starting with PHP 7):

$variable = $array['A'] ?? null

does exactly the same as your code.

Quoting the RFC:

The coalesce, or ??, operator is added, which returns the result of its first operand if it exists and is not NULL, or else its second operand. This means the $_GET['mykey'] ?? "" is completely safe and will not raise an E_NOTICE

The old way (hackish workaround):

$variable = @$array['A'] ?: null;

This uses the error suppression operator @ to silence the notice, and the short ternary operator ?:. If we only need to set $variable to null if $array['A'] is not set, it can be shortened to

$variable = @$array['A'];

It should be noted that @ is considered bad practice and I actually feel a bit dirty recommending it, but if you can live with the occasional best practice violation, this is a situation where it does not do harm:

There is only one possible error that can happen in this line (undefined variable/offset). You expect it and handle it gracefully.
