Bug #78505 [NEW]: casting stdClass to string now unrecoverable fatal error

From: phofstetter at sensational dot ch Operating system: macOS, Debian Linux PHP version: 7.4.0RC1 Package: *General Issues Bug Type: Bug Bug description:casting stdClass to string now unrecoverable fatal error Description: ------------ In previous releases of PHP, casting instances of stdClass to string would raise an E_RECOVERABLE_ERROR, but in 7.4, this has changed to raise a E_ERROR fatal error. I'm not entirely sure this increase of severity is entirely justified as catching fatal errors in production is still annoying and hard to get meaningful backtraces reported. Test script: --------------- <?php set_error_handler(function($errno, $errstr, $errfile, $errline){ if((error_reporting() & $errno) === 0){ return true; } throw new ErrorException($errstr, 0, $errno, $errfile, $errline); }); try { (string)new stdClass; } catch (ErrorException $e){ echo "caught\n"; } Expected result: ---------------- "caught" Actual result: -------------- PHP Fatal error: Uncaught Error: Object of class stdClass could not be converted to string in /var/webapps/popscan/flupp.php:11 Stack trace: #0 {main} thrown in /var/webapps/popscan/flupp.php on line 11 Fatal error: Uncaught Error: Object of class stdClass could not be converted to string in /var/webapps/popscan/flupp.php:11 Stack trace: #0 {main} thrown in /var/webapps/popscan/flupp.php on line 11 -- Edit bug report at https://bugs.php.net/bug.php?id=78505&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=78505&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=78505&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=78505&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=78505&r=needscript Try newer version: https://bugs.php.net/fix.php?id=78505&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=78505&r=support Expected behavior: https://bugs.php.net/fix.php?id=78505&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=78505&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=78505&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=78505&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=78505&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=78505&r=dst IIS Stability: https://bugs.php.net/fix.php?id=78505&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=78505&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=78505&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=78505&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=78505&r=mysqlcfg
