Are there any best practices or alternative methods for handling and displaying grouped data in PHP applications?

When handling and displaying grouped data in PHP applications, one common approach is to use arrays to store and organize the data based on certain criteria. This allows for easy manipulation and iteration over the grouped data to display it in a structured format. Another alternative method is to use PHP's built-in functions like array_map or array_reduce to process and group the data efficiently. 

// Sample code snippet to group data by a specific key in an array

$data = [
    ['name' => 'John', 'age' => 25],
    ['name' => 'Jane', 'age' => 30],
    ['name' => 'Alice', 'age' => 25],
    ['name' => 'Bob', 'age' => 30]
];

$groupedData = [];

foreach ($data as $item) {
    $key = $item['age'];
    
    if (!array_key_exists($key, $groupedData)) {
        $groupedData[$key] = [];
    }
    
    $groupedData[$key][] = $item;
}

// Display grouped data
foreach ($groupedData as $key => $group) {
    echo "Group $key:\n";
    
    foreach ($group as $item) {
        echo $item['name'] . "\n";
    }
}
