Hi everyone,
Here's an RFC that would extend the syntax of list() to be more useful
with associative arrays:
https://wiki.php.net/rfc/list_keys
Please read it and tell me your thoughts.
Nice, Andrea, thanks! Destructuring is quite handy.
I wonder if there is opportunity to include array gathering. Something
along the lines of:
list ('foo' => $foo, ...$rest) = [ 'foo' => 1, 'bar' => 2, 'baz' => 3];
assert $foo === 1;
assert $rest === [ 'bar' => 2, 'baz' => 3];
What do you think?
That might be useful, and it's certainly intuitive. In languages with
linked lists like Haskell, you can pattern-match the rest of a list, so
there's a precedent. Though with linked lists it's an O(1) operation,
while this is O(n).
I don't think that should go into this RFC specifically, though, but it
could be a future enhancement.
Thanks!
