Are there any best practices for efficiently sorting and displaying data in PHP, especially when dealing with multiple entries for the same identifier?

When dealing with multiple entries for the same identifier in PHP, a common approach is to use arrays to store the data and then sort and display it accordingly. One efficient way to achieve this is by using the `usort` function along with a custom sorting function that compares the entries based on a specific criteria. By sorting the data before displaying it, you can ensure a consistent and organized presentation of the information. 

// Sample data with multiple entries for the same identifier
$data = [
    ['id' => 1, 'name' => 'John', 'age' => 25],
    ['id' => 2, 'name' => 'Alice', 'age' => 30],
    ['id' => 1, 'name' => 'Bob', 'age' => 28],
    ['id' => 3, 'name' => 'Eve', 'age' => 22]
];

// Custom sorting function to sort data based on 'id' in ascending order
usort($data, function($a, $b) {
    return $a['id'] - $b['id'];
});

// Display sorted data
foreach ($data as $entry) {
    echo "ID: " . $entry['id'] . " | Name: " . $entry['name'] . " | Age: " . $entry['age'] . "\n";
}
