Foreach loops on multidimensional arrays in PHP

#php

Inspired by https://bit.ly/3psMXqD

If you have a multidimensional array you don’t have to procced it like this:

<?php $array = [ ["AA", "AB", ["ACA", "ACD"] ], ["BA", "BB", ["BCA", "BCD"] ], ["CA", "CB", ["CCA", "CCD"] ], ]; foreach($array as $a){ foreach($a as $b){ if(is_array($b)){ foreach($b as $c){ echo "$c "; } }else{ echo "$b "; } } } ?>
Enter fullscreen mode Exit fullscreen mode

You can simply make it like this:

<?php $array = [ ["AA", "AB", ["ACA", "ACD"] ], ["BA", "BB", ["BCA", "BCD"] ], ["CA", "CB", ["CCA", "CCD"] ], ]; foreach($array as list($a, $b, list($c, $d))) { echo "$a $b $c $d "; }; ?>
Enter fullscreen mode Exit fullscreen mode

For every new dimension you just need to add a new dimension of the list() function.
