#28458 [NEW]: Problem storing objects in Session

From: chrispeery at cox dot net Operating system: Red Hat Linux 2.4.9-e.12 PHP version: 5.0.0RC2 PHP Bug Type: Session related Bug description: Problem storing objects in Session Description: ------------ The problem occurs when you store an object into the session and then try and create a local copy of that object. In PHP version 4.3.4 when you create the local copy of the object and modify it the object in the session does not change. However with PHP 5.0.0RC2 when you modify the local copy of the object it will also modify the object that is stored in the session. Is this the desired behavior for the newer version. Also one more thing to point out, if your working with any other datatype like array or strings stored in the session this does not happen. Reproduce code: --------------- <?php session_start(); echo("<br><br><hr>TEST SESSION WITH OBJECT<br>"); $my_object = (object) array('value_one'=>'1'); $_SESSION['TEST_OBJECT'] = $my_object; $local_object_copy = $_SESSION['TEST_OBJECT']; echo("SESSION BEFORE:<br>"); var_dump($_SESSION['TEST_OBJECT']); echo("<br><br>"); echo("LOCAL COPY BEFORE:<br>"); var_dump($local_object_copy); echo("<br><br>"); $local_object_copy->value_one = '2'; echo("SESSION AFTER:<br>"); var_dump($_SESSION['TEST_OBJECT']); echo("<br><br>"); echo("LOCAL COPY AFTER:<br>"); var_dump($local_object_copy); ?> Expected result: ---------------- I would expect for the local copy of the object to be modified and the object stored in the Session not to be modified. Unless of course I explicity set my local variable like so ($local_object_copy =& $_SESSION['TEST_OBJECT'];) Actual result: -------------- The actual result is that the object stored in the session has the exact same value as the local copy I created. -- Edit bug report at http://bugs.php.net/?id=28458&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=28458&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=28458&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=28458&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=28458&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=28458&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=28458&r=needscript Try newer version: http://bugs.php.net/fix.php?id=28458&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=28458&r=support Expected behavior: http://bugs.php.net/fix.php?id=28458&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=28458&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=28458&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=28458&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=28458&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=28458&r=dst IIS Stability: http://bugs.php.net/fix.php?id=28458&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=28458&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=28458&r=float
