Recently I wanted to find the transpose of an array. But there is no inbuilt function for doing that. This code can find the transpose of a 2D array. If an optional second parameter is passed, then the function returns that row of the new matrix.

<?php
function array_transpose($array, $selectKey = false) {
    if (!
is_array($array)) return false;
   
$return = array();
    foreach(
$array as $key => $value) {
        if (!
is_array($value)) return $array;
        if (
$selectKey) {
            if (isset(
$value[$selectKey])) $return[] = $value[$selectKey];
        } else {
            foreach (
$value as $key2 => $value2) {
               
$return[$key2][$key] = $value2;
            }
        }
    }
    return
$return;
}
$fruits = array(
    array(
'id' => 1, 'name' => 'Apple', 'color' => 'Red'),
    array(
'id' => 2, 'name' => 'Orange', 'color' => 'Orange'),
    array(
'id' => 3, 'name' => 'Mango', 'color' => 'Yellow')
);

print_r(array_transpose($fruits));
print_r(array_transpose($fruits, 'name'));

?>
