class a {
public function __construct() {
$this->rand = mt_rand();
}
}
function retrieve_records () {
return array(
new a,
new a,
new a,
new a,
new a,
);
}
$records = retrieve_records();
$recordlist = array();
foreach ($records as $record) {
array_push ($recordlist, $record);
}
die(var_dump($recordlist));
gives me:
array(5) {
[0]=>
object(a)#1 (1) {
["rand"]=>
int(515141845)
}
[1]=>
object(a)#2 (1) {
["rand"]=>
int(804365869)
}
[2]=>
object(a)#3 (1) {
["rand"]=>
int(32698894)
}
[3]=>
object(a)#4 (1) {
["rand"]=>
int(1375725959)
}
[4]=>
object(a)#5 (1) {
["rand"]=>
int(100662005)
}
}
I'd say there's a problem in your code. Check where you might be using
references, chances are you're using one somewhere and not unsetting
it afterwards.
