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

When manipulating and updating arrays in PHP, it is important to use built-in array functions to ensure efficiency and maintainability of the code. Some best practices include using functions like array_push(), array_pop(), array_shift(), array_unshift(), array_merge(), and array_slice() to add, remove, merge, or extract elements from arrays. 

// Example of manipulating and updating arrays in PHP

// Initializing an array
$numbers = [1, 2, 3, 4, 5];

// Adding an element to the end of the array
array_push($numbers, 6);

// Removing the last element from the array
array_pop($numbers);

// Adding an element to the beginning of the array
array_unshift($numbers, 0);

// Removing the first element from the array
array_shift($numbers);

// Merging two arrays
$moreNumbers = [7, 8, 9];
$combinedNumbers = array_merge($numbers, $moreNumbers);

// Extracting a portion of the array
$slicedNumbers = array_slice($combinedNumbers, 2, 3);

// Output the modified array
print_r($slicedNumbers);
