This lesson introduces the use of heaps and priority queues in PHP, focusing on the `SplPriorityQueue` from the Standard PHP Library. It explains the concept of heaps as binary trees maintaining order relations and demonstrates how PHP's priority queue can efficiently process elements based on priority. The lesson includes a practical example to find the k largest elements in a list and ...

The SplPriorityQueue class provides the main functionalities of a prioritized queue, implemented using a max heap. Note: The order of elements with identical priority is undefined. It may differ from the order in which they have been inserted.
The `SplPriorityQueue::key` function is a built-in PHP function that returns the index of the current node in a priority queue. This function is specifically used with the `SplPriorityQueue` class, which is an implementation of the `PriorityQueue` interface in PHP.
