Hi Internals,
I'm wondering if there's any reason why array_merge() doesn't allow zero
arrays to be passed?
`array_merge()`; // Warning: `array_merge()` expects at least 1 parameter,
0 given
It would be reasonable IMO to return an empty array in this case. The
reason is, I'm often using it this way:
$result = [];
foreach (...) {
$result[] = getSomeListOfItems();
}
if (! $result) {
return [];
}
return array_merge(...$result);
If we allowed zero arrays to be passed, I could get rid of this repeated
empty array check before array_merge().
