(PHP 5 >= 5.1.0, PHP 7, PHP 8)
SplObjectStorage::next — Move to the next entry
Moves the iterator to the next object in the storage.
此函数没有参数。
没有返回值。
示例 #1 SplObjectStorage::next() example
<?php
$s = new SplObjectStorage();
$o1 = new StdClass;
$o2 = new StdClass;
$s->attach($o1, "d1");
$s->attach($o2, "d2");
$s->rewind();
while($s->valid()) {
$index = $s->key();
$object = $s->current(); // similar to current($s)
var_dump($index);
var_dump($object);
$s->next();
}
?>
以上例程的输出类似于:
int(0) object(stdClass)#2 (0) { } int(1) object(stdClass)#3 (0) { }
