From: woody dot gilk at gmail dot com Operating system: Mac OSX 10.5 PHP version: 5.2.10 PHP Bug Type: Scripting Engine problem Bug description: Invalid error reporting with __toString() method
Description: ------------ When using a custom error handler, it is possible to make PHP trigger an E_FATAL by concatenating an object with a __toString() method together with a variable that is not set. Tested in 5.2.9 and 5.2.10. Reproduce code: --------------- <?php class test { public static function error_handler($code, $error, $file = NULL, $line = NULL) { // This error is not suppressed by current error reporting settings throw new ErrorException($error, $code, 0, $file, $line); } public static function run() { $object = new self; echo $object.$foo; } public function __toString() { return __CLASS__; } } error_reporting(E_ALL); set_error_handler(array('test', 'error_handler')); test::run(); Expected result: ---------------- PHP Fatal error: Uncaught exception 'ErrorException' with message 'Undefined variable: foo' in php_bug.php:15 Stack trace: #0 php_bug.php(15): test::error_handler() #1 php_bug.php(29): test::run() #2 {main} thrown in php_bug.php on line 15 Actual result: -------------- PHP Fatal error: Method test::__toString() must not throw an exception in -- Edit bug report at http://bugs.php.net/?id=48622&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48622&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48622&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48622&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48622&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48622&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48622&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48622&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48622&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48622&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48622&r=support Expected behavior: http://bugs.php.net/fix.php?id=48622&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48622&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48622&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48622&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48622&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48622&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48622&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48622&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48622&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48622&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48622&r=mysqlcfg
