What steps can be taken to improve the algorithm for sorting elements in PHP based on specific criteria?

To improve the algorithm for sorting elements in PHP based on specific criteria, we can use the `usort()` function along with a custom comparison function. This allows us to define our own sorting logic based on the specific criteria we want to prioritize. 

// Sample array of elements to be sorted
$elements = [
    ['name' => 'John', 'age' => 30],
    ['name' => 'Alice', 'age' => 25],
    ['name' => 'Bob', 'age' => 35]
];

// Custom comparison function based on age
usort($elements, function($a, $b) {
    return $a['age'] - $b['age'];
});

// Output the sorted elements
foreach ($elements as $element) {
    echo $element['name'] . ' - ' . $element['age'] . PHP_EOL;
}
