The SplQueue class provides the main functionalities of a queue implemented using a doubly linked list by
setting the iterator mode to SplDoublyLinkedList::IT_MODE_FIFO
.
Example #1 SplQueue example
<?php$q = new SplQueue();$q[] = 1;$q[] = 2;$q[] = 3;foreach ($q as $elem) { echo $elem."\n";}?>
The above example will output:
1 2 3
Example #2 Efficiently handling tasks with SplQueue
<?php$q = new SplQueue();$q->setIteratorMode(SplQueue::IT_MODE_DELETE);// ... enqueue some tasks on the queue ...// process themforeach ($q as $task) { // ... process $task ... // add new tasks on the queue $q[] = $newTask; // ...}?>
