What is the best practice for sorting a multidimensional array in PHP based on a specific value within the array?

When sorting a multidimensional array in PHP based on a specific value within the array, you can use the `usort()` function along with a custom comparison function. This function will compare the specific value you want to sort by for each element in the array. By defining a custom comparison function, you can specify the sorting order based on the specific value. 

// Sample multidimensional array
$users = [
    ['name' => 'John', 'age' => 30],
    ['name' => 'Alice', 'age' => 25],
    ['name' => 'Bob', 'age' => 35]
];

// Sort the array based on the 'age' value in ascending order
usort($users, function($a, $b) {
    return $a['age'] <=> $b['age'];
});

// Output the sorted array
print_r($users);
