Bug description:spl_get_object_by_hash()
Description:
------------
class a{}
$object = new a();
$object2 = spl_get_object_by_hash(spl_object_hash($object));
var_dump($object === $object2); // true (same object)
NOTE: When using spl_get_object_by_hash, you must know that $object must be
alive
else function can return another object.
Primary usage example in test script:
Test script:
---------------
class a{
protected $_b;
public function getB(){
return spl_get_object_by_hash($this->_b);
}
public function doSomething(){
$b = $this->getB();
// here I can use $b !
}
public function __construct($b){
$this->_b = spl_object_hash($b);
}
}
class b{
protected $_a;
public function getA(){
return $this->_a;
}
public function __construct(){
$this->_a = new a($this);
}
public function __destruct(){
echo 'destroyed';
}
}
$b = new b();
$b->getA()->doSomething();
unset($b); // destroyed !! this IS NOT POSSIBLE without
spl_get_object_by_hash()
