Hello php-dev,
PHP4.3.0RC1
Source
----------------------------
<?
$globalref_foo = array();
$globalref_bar = null;
class Foo {
function Foo()
{
global $globalref_foo;
$globalref_foo[] = &$this;
}
}
class Bar {
function Bar()
{
global $globalref_bar;
$globalref_bar = &$this;
}
}
$o1 = &new Foo();
$o2 = &new Bar();
var_dump($globalref_foo);
var_dump($globalref_bar);
var_dump($o1);
var_dump($o2);
?>
Output:
----------------------------
array(1) {
[0]=>
&object(foo)(0) {
}
}
NULL
object(foo)(0) {
}
object(bar)(0) {
}
Question:
----------------------------
Why $globalref_bar===NULL after $o2 = &new Bar(); ?
Why
