What is the implementation principle of queue in PHP? aiming at this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Queue is a special linear table, which can only be deleted at the front end of the table, which can be called front, while at the back end of the table, it can be called rear for insert operation. A queue, like a stack, is a linear table with limited operation, which differs from the stack in that it follows the "first-in, first-out" principle, while the stack follows the "first-in, first-out" principle. The end of the queue for insertion operation is called the end of the queue, and the end of the queue for deletion operation is called the head of the queue. The insertion operation is only allowed at the end of the queue and the deletion operation is carried out at the head of the queue.

The data element of the queue is also known as the queue element, inserting an element at the end of the queue is called queuing, and deleting an element at the head of the queue is called dequeuing. Specific implementation reference code:
