What are the best practices for sorting and displaying arrays in PHP based on specific values?

When sorting and displaying arrays in PHP based on specific values, the best practice is to use the `usort()` function along with a custom comparison function. This allows you to define how the array should be sorted based on the specific values you want to prioritize. By implementing a custom comparison function, you can easily customize the sorting logic to meet your specific requirements. 

// Sample array to be sorted based on 'value' key
$array = [
    ['name' => 'John', 'value' => 20],
    ['name' => 'Jane', 'value' => 15],
    ['name' => 'Alice', 'value' => 25],
];

// Custom comparison function to sort based on 'value' key
usort($array, function($a, $b) {
    return $a['value'] <=> $b['value']; // Sort in ascending order
});

// Display the sorted array
foreach ($array as $item) {
    echo $item['name'] . ': ' . $item['value'] . PHP_EOL;
}
