From: j dot henge-ernst at interexa dot de Operating system: linux PHP version: 5.1.6 PHP Bug Type: Scripting Engine problem Bug description: cloning and and references inside the objects
Description: ------------ I encountered a problem similar to the bug #27268 http://bugs.php.net/bug.php?id=27268 The attribut b of the cloned object is still pointing to the attribut of its original object. So changing the attribut in the cloned object also changes the attribute in the original object. Reproduce code: --------------- <?php class a { protected $a = array(); protected $b = ''; public function __construct($b) { $this->b = $b; $this->a['f'] = &$this->b; } public function setB($b) { $this->b = $b; } public function printB() { echo __CLASS__ . $this->b . '/' . $this->a['f'] ."\n"; } public function __clone() { unset($this->a['f']); $this->a['f'] = &$this->b; } } $x1 = new a(5); $x2 = clone $x1; $x2->setB(7); $x1->printB(); $x2->printB(); Expected result: ---------------- a5/5 a7/7 Actual result: -------------- a7/7 a7/7 -- Edit bug report at http://bugs.php.net/?id=38788&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=38788&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=38788&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=38788&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=38788&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=38788&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=38788&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=38788&r=needscript Try newer version: http://bugs.php.net/fix.php?id=38788&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=38788&r=support Expected behavior: http://bugs.php.net/fix.php?id=38788&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=38788&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=38788&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=38788&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=38788&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=38788&r=dst IIS Stability: http://bugs.php.net/fix.php?id=38788&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=38788&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=38788&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=38788&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=38788&r=mysqlcfg
