PHP 5

array_column doesn't work with an array of objects. Use array_map instead:

$titles = array_map(function($e) {
    return is_object(e->Title : $e['Title'];
}, $records);

PHP 7

array_column()

The function now supports an array of objects as well as two-dimensional arrays. Only public properties are considered, and objects that make use of __get() for dynamic properties must also implement __isset().

See https://github.com/php/php-src/blob/PHP-7.0.0/UPGRADING#L629 - Thanks to Bell for the hint!

No, there is not a function to get your expected output natively, though you can make your own functions, just use array_column to get the types/column, and then loop over your array, on match remove the item as to not duplicate iterations.

Something like:

<?php
$data = [
    ['foodType' => 'fruits', 'itemID' => 1, 'itemName' => 'apple'],
    ['foodType' => 'fruits', 'itemID' => 2, 'itemName' => 'banana'],
    ['foodType' => 'veggies', 'itemID' => 3, 'itemName' => 'carrot'],
    ['foodType' => 'veggies', 'itemID' => 4, 'itemName' => 'broccoli']
];

function array_column_multi ($array, $column) {
    $types = array_unique(array_column($array, $column));

    $return = [];
    foreach ($types as $type) {
        foreach ($array as $key => $value) {
            if ($type === $value[$column]) {
                unset($value[$column]);
                $return[$type][] = $value;
                unset($array[$key]);
            }
        }
    }
    return $return;
}


print_r(array_column_multi($data, 'foodType'));

Result:

Array

    [fruits] => Array
        (
            [0] => Array
                (
                    [itemID] => 1
                    [itemName] => apple
                )

            [1] => Array
                (
                    [itemID] => 2
                    [itemName] => banana
                )

        )

    [veggies] => Array
        (
            [0] => Array
                (
