What are the advantages and disadvantages of sorting multidimensional arrays in PHP versus sorting data directly from a database?

When deciding whether to sort multidimensional arrays in PHP or directly from a database, it is important to consider factors such as performance, flexibility, and data size. Sorting data directly from a database can be more efficient for large datasets as it utilizes the database's indexing and querying capabilities. However, sorting multidimensional arrays in PHP can offer more flexibility in terms of custom sorting algorithms and can be easier to implement for smaller datasets. 

// Sorting multidimensional array in PHP
$users = [
    ['name' => 'Alice', 'age' => 25],
    ['name' => 'Bob', 'age' => 30],
    ['name' => 'Eve', 'age' => 20]
];

// Sort by age
usort($users, function($a, $b) {
    return $a['age'] - $b['age'];
});

print_r($users);
