The unique identifiers of destroyed objects can and will be reused. <?php class Foo{ private static $test = 0; public function __construct(){ self::$test++; } } $foo1 = new Foo(); $foo2 = new Foo(); $foo3 = new Foo(); //new unique identifier echo spl_object_hash($foo1)."<br />\n"; //new unique identifier echo spl_object_hash($foo2)."<br />\n"; //new unique identifier echo spl_object_hash($foo3)."<br />\n"; $foo1 = new Foo(); //new unique identifier because, when we created Foo, foo1 still existed echo spl_object_hash($foo1)."<br />\n"; $foo1 = new Foo(); //same identifier as the first $foo1 because it was destroyed, //thus released the identifier echo spl_object_hash($foo1)."<br />\n"; ?> This will output something like: 000000007ec3fcb5000000003f984510 000000007ec3fcb6000000003f984510 000000007ec3fcb7000000003f984510 000000007ec3fcb0000000003f984510 000000007ec3fcb5000000003f984510
