Are there any recommended resources or guides for optimizing array manipulation in PHP?

When working with arrays in PHP, it's important to optimize array manipulation to improve performance and efficiency. One way to do this is by using built-in array functions such as array_map, array_filter, and array_reduce instead of manual loops. Additionally, utilizing associative arrays and multidimensional arrays effectively can also help streamline operations.

// Example of optimizing array manipulation in PHP using array_map function
$numbers = [1, 2, 3, 4, 5];

// Doubling each element in the array using array_map
$doubledNumbers = array_map(function($num) {
    return $num * 2;
}, $numbers);

print_r($doubledNumbers);
