Bug #79769 [NEW]: PDO throws non-PDO exeptions

From: morozov at tut dot by Operating system: Linux PHP version: 7.4.7 Package: PDO Core Bug Type: Bug Bug description:PDO throws non-PDO exeptions Description: ------------ When interacting with a PDOStatement object, the consumer should be able to expect all exceptions to be reported as PDOException. However, in certain cases, the extension leaks its internal implementation details and throws an Error. Test script: --------------- <?php $conn = new PDO('sqlite:memory:'); $stmt = $conn->prepare('SELECT ?'); $stmt->bindValue(1, new DateTime()); try { $stmt->bindValue(1, new DateTime()); } catch (Throwable $e) { echo get_class($e), ': ', $e->getMessage(), PHP_EOL; } try { $stmt->execute([new DateTime()]); } catch (Throwable $e) { echo get_class($e), ': ', $e->getMessage(), PHP_EOL; } // the above seems to be implemented just by casting the value to a string since it behaves exactly as the following: try { (string) (new DateTime()); } catch (Throwable $e) { echo get_class($e), ': ', $e->getMessage(), PHP_EOL; } Expected result: ---------------- A PDOException is thrown instead of an Error PDOException: Some message that says that this type cannot be bound to the statement Actual result: -------------- Error: Object of class DateTime could not be converted to string -- Edit bug report at https://bugs.php.net/bug.php?id=79769&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=79769&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=79769&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=79769&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=79769&r=needscript Try newer version: https://bugs.php.net/fix.php?id=79769&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=79769&r=support Expected behavior: https://bugs.php.net/fix.php?id=79769&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=79769&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=79769&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=79769&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=79769&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=79769&r=dst IIS Stability: https://bugs.php.net/fix.php?id=79769&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=79769&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=79769&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=79769&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=79769&r=mysqlcfg
