throwing exception from variable creates clone of object without copying properties

[gregzawadzki]

Description

The following code:

<?php
$exception = new Exception('2312');
try {
	
// throw new Exception('2312'); // this line works OK.
throw new $exception;
 
} catch (Exception $e){
	var_dump(spl_object_id($e));
	echo 'Message: '.$e->getMessage();
}

Resulted in this output:

int(2)
Message: 

But I expected this output instead:

int(1)
Message: 2312

PHP Seems to clone $exception and not copy message (tested only message)

PHP Version

5.6 to 8.4.10

Operating System

All

Nevermind... I didn't notice (and didn't know) it was possible to create object from object.
