Example #1 SplObjectStorage::attach() example
<?php
$o1 = new StdClass;
$o2 = new StdClass;
$s = new SplObjectStorage();
$s->attach($o1); // similar to $s[$o1] = NULL;
$s->attach($o2, "hello"); // similar to $s[$o2] = "hello";
var_dump($s[$o1]);
var_dump($s[$o2]);
?>
The above example will output something similar to:
NULL string(5) "hello"
