What are some best practices for efficiently sorting and manipulating data in PHP arrays retrieved from MySQL?

When working with data retrieved from MySQL in PHP arrays, it is important to efficiently sort and manipulate the data to achieve desired results. One best practice is to use built-in PHP functions like array_multisort() for sorting arrays based on multiple criteria. Additionally, leveraging array_map() and array_filter() can help manipulate the data effectively by applying functions to each element or filtering out unwanted elements. 

// Example of sorting and manipulating data in PHP arrays retrieved from MySQL

// Retrieve data from MySQL and store in $data array

// Sorting the data based on a specific key in ascending order
array_multisort(array_column($data, 'name'), SORT_ASC, $data);

// Manipulating the data by applying a custom function to each element
$manipulatedData = array_map(function($item) {
    // Manipulate each item here
    return $item;
}, $data);

// Filtering out unwanted elements from the data
$filteredData = array_filter($data, function($item) {
    // Add condition to filter here
    return true; // Return true to keep the item, false to filter it out
});
