How to restructure multi-dimensional array with columns as rows?

Question

Is there an efficient way to change the structure of this multidimensional array? I want to group the column values.

//$arrayBefore
[[5, 4, 10], [11, 13, 15], [32, 14, 15]];

Desired result:

//$arrayAfter
[[5, 11, 32], [4, 13, 14], [10, 15, 15]]; 

Answer 1

You can do it based on array_column():-

<?php

$array = [[5, 4, 10], [11, 13, 15], [32, 14, 15]];

$final_array = [array_column($array,0),array_column($array,1),array_column($array,2)];

print_r($final_array );

Note:- above code will work only for this array.

More general and considering all aspects code is using foreach():-

<?php
$array = [[5, 4, 10], [11, 13, 15], [32, 14, 15]];

$final_array = array();

foreach($array as $arr){
    foreach($arr as $key=>$value){
      $final_array[$key][]=$value;
    }
}
print_r($final_array);
