Is There a PHP Equivalent to Python\'s zip() Function?

Does PHP Offer a Function Similar to Python's zip()?

Python's zip() function is known for its convenience in merging multiple iterable sequences into a single sequence of tuples. PHP developers often seek an analogous function for seamless data amalgamation.

PHP's Equivalent: array_map with Null as the First Argument

Thankfully, PHP provides a substitute using the array_map function. By employing null as the first argument, array_map emulates the behavior of zip().

$a = ["a", "b", "c"];
$b = [1, 2, 3];
$c = ["foo", "bar", "baz"];

$merged_data = array_map(null, $a, $b, $c);

This code will produce an array of tuples, with each tuple containing corresponding elements from the three input arrays:

[
    ["a", 1, "foo"],
    ["b", 2, "bar"],
    ["c", 3, "baz"],
]

Handling Unequal Array Lengths

Unlike Python's zip(), which returns a result that matches the length of the shortest array, PHP's array_map instead pads shorter arrays with null values to match the length of the longest array. This behavior ensures consistent output even with arrays of varying sizes.
