From: peter dot evertz at snafu dot de Operating system: Linux 2.6.18 PHP version: 5.2.4RC1 PHP Bug Type: Session related Bug description: class member is broken after retrieving vom Session Description: ------------ I found this while using propel. It uses DateTime class for storing. After retrieving the class from a Session the member is broken. The code creates a session variabel "v" with the given class if not found.On the second call to the script the class is retrievies from session. The member x is broken. Reproduce code: --------------- <?php class c { protected $v; function print_type() { if ( $this->v instanceof DateTime ) { print "x is DateTime\n"; } } function get_v() { return $this->v; } function set_v($i) { $this->v=$i; } } session_start(); if ( !isset($_SESSION["x"] )) { $x = new c(); $x->set_v( new DateTime()); $_SESSION["x"]=$x; print "New object created\n"; } $_SESSION["x"]->print_type(); print $_SESSION["x"]->get_v()->format("d.m.Y"); ?> Expected result: ---------------- First call: New object created x is DateTime 08.08.2007 Second call: x is DateTime 08.08.2007 Actual result: -------------- First call: New object created x is DateTime 08.08.2007 Second call: x is DateTime Warning: DateTime::format(): The DateTime object has not been correctly initialized by its constructor in /home/peter/workspace/Kurse/html/t1.php on line 28 -- Edit bug report at http://bugs.php.net/?id=42239&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42239&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42239&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42239&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42239&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42239&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42239&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42239&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42239&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42239&r=support Expected behavior: http://bugs.php.net/fix.php?id=42239&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42239&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42239&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42239&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42239&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42239&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42239&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42239&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42239&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42239&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42239&r=mysqlcfg
