Good point there, thanks!
Although I not a big fan on assigning values when calling functions it is a
valid syntax, and I agree that introducing ambiguity does not make any sense.
I think these are actually the options to append multiple items to an array:
1. array_push($arr, 1, 2, 3);
2. $arr = […$arr, 1, 2, 3);
3. foreach ([1, 2, 3] as $i) {
$arr[] = $i;
}
4. foreach ([1,2,3] as $arr[]); // a bit weird, but it does work for php 5.4+[1]
I personally would go with the 2nd if posible, 1st for compatibility, but maybe
it could be a bit less redundant with the David’s proposed syntax:
$arr[] = …[1, 2, 3];
I wonder if it will even better in terms of performance…
