What are some 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 efficiently to achieve the desired results. Some best practices include using functions like array_push, array_pop, array_shift, and array_unshift for adding or removing elements, using array_map and array_filter for transforming or filtering array elements, and using array_merge or array_combine for merging or combining arrays. 

// Example of using array_push to add elements to an array
$fruits = ['apple', 'banana', 'orange'];
array_push($fruits, 'grape', 'kiwi');
print_r($fruits);
