这是代码&它的输出我用来画出如下推论：
class a {
public $var1;
public $var2;
}
$obj0 = new a;
var_dump($obj0);
class b {
public $var1;
public $var2;
public $var3;
}
$obj1 = new b;
var_dump($obj1);
$obj2 = new stdClass;
var_dump($obj2);
$obj3 = new stdClass;
var_dump($obj3);
$obj4 = new stdClass;
var_dump($obj4);
$obj5 = new stdClass;
var_dump($obj5);
var_dump(new stdClass);
$obj6 = new stdClass;
var_dump($obj6);
输出：
object(a)#1 (2) {
["var1"]=> NULL
["var2"]=> NULL
}
object(b)#2 (3) {
["var1"]=> NULL
["var2"]=> NULL
["var3"]=> NULL
}
object(stdClass)#3 (0) {
}
object(stdClass)#4 (0) {
}
object(stdClass)#5 (0) {
}
object(stdClass)#6 (0) {
}
object(stdClass)#7 (0) {
}
object(stdClass)#7 (0) {
}
#< some-number>在对象的var_dump中的行对象(someClass)旁边实际上是#< count> ;.哪里,
count is the number of objects@H_404_12@ / zval’s for objects@H_404_12@ irrespective of which class it belongs to that has been created till now. Which keeps getting incrementing for every object created & gets decremented by 1 when a refcount of a zval reaches zero i.e. Garbage Collection.
我对吗？
该数字是Z_OBJ_HANDLE_PP(struc),其中struc是一个zval,它导致Z_OBJVAL(zval).handle,它导致(zval).value.obj.

总之我会说这是object identifier用十进制格式写的(ref)：
PHP_printf("%sobject(%s)#%d (%d) {\n",COMMON,class_name,Z_OBJ_HANDLE_PP(struc),myht ? zend_hash_num_elements(myht) : 0);
而不是创建的对象的数量.
