SplQueue::__construct — Constructs a new queue implemented using a doubly linked list
This constructs a new empty queue.
Note:
This method automatically sets the iterator mode to SplDoublyLinkedList::IT_MODE_FIFO.
此函数没有参数。
没有返回值。
Example #1 SplQueue::__construct() example
<?php
$q = new SplQueue ();
$q [] = 1 ;
$q [] = 2 ;
$q [] = 3 ;
foreach ( $q as $elem ) {
echo $elem . "\n" ;
}
?>
以上例程会输出:
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 them
foreach ( $q as $task ) {
// ... process $task ...
// add new tasks on the queue
$q [] = $newTask ;
// ...
}
?>
