How to Sum a Column's Values in a Multidimensional Array Without a Foreach Loop?

Sum Value in One Column of a Multidimensional Array

This code query results in a multitude of arrays:

$array = [
    [ 'f_count' => 1, 'uid' => 105 ],
    [ 'f_count' => 0, 'uid' => 106 ],
    [ 'f_count' => 2, 'uid' => 107 ],
    [ 'f_count' => 0, 'uid' => 108 ],
    [ 'f_count' => 1, 'uid' => 109 ],
    [ 'f_count' => 0, 'uid' => 110 ],
    [ 'f_count' => 3, 'uid' => 111 ]
];

The goal is to sum the 'f_count' column without resorting to a foreach loop. For PHP 5.5 versions, there's a simple and elegant solution:

$value = array_sum(array_column($arr, 'f_count'));

array_column extracts a specific column from an array, while array_sum adds the values of an array. Combining these functions seamlessly calculates the sum of the 'f_count' column without the need for a foreach loop.
