Are there alternative methods or functions in PHP that can achieve the same result as usort for sorting arrays based on specific conditions?

When sorting arrays based on specific conditions in PHP, the usort function is commonly used. However, there are alternative methods such as using array_multisort or array_filter in combination with custom comparison functions to achieve the same result. These alternatives provide flexibility in sorting arrays based on various criteria. 

// Example of sorting an array of objects based on a custom condition using array_multisort

// Define an array of objects
$items = [
    (object)['name' => 'John', 'age' => 30],
    (object)['name' => 'Jane', 'age' => 25],
    (object)['name' => 'Alice', 'age' => 35]
];

// Custom comparison function to sort objects based on age
function compareByAge($a, $b) {
    return $a->age - $b->age;
}

// Extract ages from objects
$ages = array_column($items, 'age');

// Sort objects based on age using array_multisort
array_multisort($ages, $items);

// Output sorted array
print_r($items);
