PHP is using reference counter garbage collection so it is not able to
deallocate objects with cyclic references. But
it should not be a reason for corrupting memory. The following example
cause either loosing value of object property either segmentation fault
at PHP 4.3.1 and PHP-4.3.2RC1. The fault takes place after inserting
65533
objects (0xfffd - looks like somewhere short type is used:).
In first case after inserting about 65k of objects the system reports
"PHP Notice: Undefined property:" when
accessing "opened" field in storeObject.
<?php
class Storage {
var $opened;
var $count;
function Storage() {
$this->objByOidMap = array();
$this->opened = true;
$this->count = 0;
}
function storeObject(&$obj) {
if ($this->opened) {
if ($obj->__oid__ == 0) {
$this->count += 1;
$obj->__oid__ = $this->count;
$obj->__storage__ = &$this;
$this->objByOidMap[$obj->__oid__] = &$obj;
}
}
}
}
class Object {
var $__storage__;
var $__oid__;
}
$storage = &new Storage();
for ($i = 0; $i < 100000; $i++) {
print("i=$i\n");
$obj = &new Object();
$storage->storeObject($obj);
}
?>
