Abu Jobaer: “Nope. You could use array_walk_recursive.”

Seguy Damien @dseguy1d1b9ac93

Here is a classic situation, where injecting an array of arrays leads to the infamous list of 'Array, Array, Array...' What #PHP tool do you use to guard against this warning? is_array() is not sufficient, and the type is already there. There is nothing native available.…

$<?php declare(strict_types=1); function foo(array $array): string { return implode(', ', $array); }$

What about flattening the input if you allow nested array? or throwing an exception otherwise, i guess.

something like array(...$array), to shave off one dimension? I would argue it doesn't really test the data format, rather it handles that specific format, edge cases notwithstanding.

Nope. You could use array_walk_recursive.
