What are the best practices for handling and manipulating arrays in PHP?

When handling and manipulating arrays in PHP, it is important to use built-in array functions to efficiently perform operations such as sorting, filtering, and merging. It is also crucial to properly handle errors and edge cases to ensure the integrity of the data within the arrays.

// Example: Sorting an array in PHP
$numbers = [3, 1, 5, 2, 4];
sort($numbers);
print_r($numbers);
