Question

Python has a nice zip() function. Is there a PHP equivalent?

Answer 1

As long as all the arrays are the same length, you can use array_map with null as the first argument.

array_map(null, $a, $b, $c, ...);

If some of the arrays are shorter, they will be padded with nulls to the length of the longest, unlike python where the returned result is the length of the shortest array.
