How can PHP be utilized to handle array manipulation and sorting without relying on external databases?

PHP provides built-in functions for array manipulation and sorting, allowing developers to efficiently handle arrays without relying on external databases. By utilizing functions like array_push, array_pop, array_shift, array_unshift, array_slice, and array_sort, developers can manipulate arrays in various ways. Additionally, functions like sort, rsort, asort, ksort, arsort, and krsort can be used to sort arrays based on different criteria.

// Sample PHP code demonstrating array manipulation and sorting
$fruits = array("apple", "orange", "banana");

// Adding elements to the array
array_push($fruits, "grape");
array_unshift($fruits, "kiwi");

// Removing elements from the array
array_pop($fruits);
array_shift($fruits);

// Sorting the array
sort($fruits);

// Outputting the sorted array
print_r($fruits);
