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。
Example #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) { }
