From: fredrik at demomusic dot nu Operating system: Linux PHP version: 5.0.5 PHP Bug Type: *Programming Data Structures Bug description: Fatal error when passing object's return-value as parameter by reference
Description: ------------ A bug most likely connected with the fixed bug #31525: PHP-Changelog 5.0.5: -Fixed bug #31525 (object reference being dropped. $this getting lost). (Stas, Dmitry) (http://bugs.php.net/bug.php?id=31525) When passing an object's return-value as parameter by reference I get a fatal error for code that worked flawlessly in 5.0.4. Reproduce code: --------------- I am using the Smarty-framework. This function is from Smarty.php and is the one involved in the error: /** * assigns values to template variables by reference * * @param string $tpl_var the template variable name * @param mixed $value the referenced value to assign */ function assign_by_ref($tpl_var, &$value) { if ($tpl_var != '') $this->_tpl_vars[$tpl_var] = &$value; //Lineno 603 } Code: $smarty->assign_by_ref ('soldStatus', $object->getSoldStatus ()); //Lineno 341 For clarity, this is the getSoldStatus()-method: /** * Get the sold-status of this ad. * @return int The sold-status of this ad. */ public function getSoldStatus () { return (int) $this->soldStatus; } And for yet more clarity, from the top of getSoldStatus's class: /** * @var int This' sold-status. 0 for not sold. 1 for sold. */ protected $soldStatus; Expected result: ---------------- Is in PHP 4.0.4 Win32 and Linux, I suspect the "assign_by_ref"-method to be executed, and, I guess, after bug-fix #31525, I would expect an E_STRICT error in Smarty.php on line 603 later on. Conclusivly, as I do not have E_STRICT error_reporting on, I would expect my code to work as it did in php 5.0.4! Actual result: -------------- Fatal error: Only variables can be passed by reference in /my/path/guiFunctions.php on line 341 -- Edit bug report at http://bugs.php.net/?id=34937&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=34937&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=34937&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=34937&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=34937&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=34937&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=34937&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=34937&r=needscript Try newer version: http://bugs.php.net/fix.php?id=34937&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=34937&r=support Expected behavior: http://bugs.php.net/fix.php?id=34937&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=34937&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=34937&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=34937&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=34937&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=34937&r=dst IIS Stability: http://bugs.php.net/fix.php?id=34937&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=34937&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=34937&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=34937&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=34937&r=mysqlcfg
