SplDoublyLinkedList::getIteratorMode()函數是PHP中的一個內置函數,用於返回迭代模式。
用法:
int SplDoublyLinkedList::getIteratorMode( void )
參數:該函數不接受任何參數。
返回值:該函數返回影響迭代的不同模式和標誌。
以下示例程序旨在說明PHP中的SplDoublyLinkedList::getIteratorMode()函數:
示例1:
<?php
// Declare an empty SplDoublyLinkedList
$list = new SplDoublyLinkedList();
// Add the element into SplDoublyLinkedList
$list->setIteratorMode(SplDoublyLinkedList::IT_MODE_FIFO);
// Use getIteratorMode() function
$mode = $list->getIteratorMode();
var_dump($mode);
// Add the element into SplDoublyLinkedList
$list->setIteratorMode(SplDoublyLinkedList::IT_MODE_DELETE);
// Use getIteratorMode() function
$mode = $list->getIteratorMode();
var_dump($mode);
// Add the element into SplDoublyLinkedList
$list->setIteratorMode(SplDoublyLinkedList::IT_MODE_LIFO);
// Use getIteratorMode() function
$mode = $list->getIteratorMode();
var_dump($mode);
?>
輸出:
int(0) int(1) int(2)
示例2:
<?php
// Declare an empty SplDoublyLinkedList
$list = new SplDoublyLinkedList();
// Add the element into SplDoublyLinkedList
$list->setIteratorMode(SplDoublyLinkedList::IT_MODE_FIFO
| SplDoublyLinkedList::IT_MODE_DELETE
| SplDoublyLinkedList::IT_MODE_LIFO);
$mode = $list->getIteratorMode();
var_dump($mode & SplDoublyLinkedList::IT_MODE_FIFO);
var_dump($mode & SplDoublyLinkedList::IT_MODE_LIFO);
var_dump($mode & SplDoublyLinkedList::IT_MODE_DELETE);
var_dump($mode & SplDoublyLinkedList::IT_MODE_KEEP);
?>
輸出:
int(0) int(2) int(1) int(0)
