The null coalescing assignment operator is a shorthand for null coalescing operations.
Let’s take a example code
|
1 |
$data['date'] = $data['date'] ?? new DateTime(); |
So, instead of writing the previous code, we could write the following:
|
1 |
$data['date'] ??= new DateTime(); |
If the value of the left-hand parameter is null, then the value of the right-hand parameter is used.
