Are there any recommended resources or tutorials for learning how to efficiently sort and categorize data in PHP?

To efficiently sort and categorize data in PHP, one can use functions like `usort()` and `array_multisort()` to sort arrays based on specific criteria. Additionally, one can use associative arrays to categorize data based on certain keys or values. It is also helpful to use loops and conditional statements to iterate through the data and organize it accordingly. 

// Sample array of data to be sorted and categorized
$data = [
    ['name' => 'John', 'age' => 25, 'category' => 'A'],
    ['name' => 'Jane', 'age' => 30, 'category' => 'B'],
    ['name' => 'Bob', 'age' => 28, 'category' => 'A'],
    ['name' => 'Alice', 'age' => 22, 'category' => 'B'],
];

// Sort the data based on age
usort($data, function($a, $b) {
    return $a['age'] - $b['age'];
});

// Categorize the data based on category
$categorizedData = [];
foreach ($data as $item) {
    $category = $item['category'];
    $categorizedData[$category][] = $item;
}

// Output the categorized data
print_r($categorizedData);
