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 ();
}
 ?>

int(0)
object(stdClass)#2 (0) {
}
int(1)
object(stdClass)#3 (0) {
}
