ID: 50250 Updated by: rquadl...@php.net Reported By: bran...@php.net Status: Open Bug Type: Scripting Engine problem Operating System: Irrelevent PHP Version: 5.3.1 New Comment:
Amendeded the code slightly ... <?php echo "\n", PHP_VERSION; if (function_exists('spl_autoload_register')) { function autoload($class) { throw new Exception('test'); require $class . '.php'; } spl_autoload_register('autoload'); } else { function __autoload($class) { throw new Exception('test'); require $class . '.php'; } } try { new NoExist(); } catch (Exception $e) { echo "unable to load the class.\n"; } 5.0.0 Fatal error: __autoload(NoExist) threw an exception of type 'Exception' in Z:\testauto.php on line 29 5.0.1 - 5.0.5 Fatal error: Function __autoload(NoExist) threw an exception of type 'Exception' in Z:\testauto.php on line 29 5.1.0 - 5.2.11 Fatal error: Class 'NoExist' not found in Z:\testauto.php on line 29 5.3.0 - 5.3.1 unable to load the class. And using MissingException 5.0.0 - 5.0-5 Fatal error: Class 'MissingException' not found in Z:\testauto.php on line 12 5.1.0 - 5.3.1 Fatal error: Class 'MissingException' not found in Z:\testauto.php on line 6 Previous Comments: ------------------------------------------------------------------------ [2009-11-23 11:36:21] rquadl...@php.net One instance where the documentation does hold true is attempting to throw an exception of a type which is not available. Changing ... throw new Exception('test'); to ... throw new MissingException('test'); results in ... Fatal error: Class 'MissingException' not found in Z:\testauto.php on line 6 I wonder if this is what the documentation is relating to. ------------------------------------------------------------------------ [2009-11-20 20:14:30] bj...@php.net This is also true for __autoload(), not only spl_register_autoload(). Bug or expected behavior as of PHP 5.3.0? ------------------------------------------------------------------------ [2009-11-20 19:50:03] bran...@php.net Description: ------------ According to the PHP documentation, exceptions cannot be thrown inside __autoload() functions, and prior to PHP 5.3, exceptions thrown resulted in fatal errors. Since PHP 5.3, it has been possible to throw and catch exceptions from __autoload() functions. I'm happy to chalk this up to a documentation bug, and if it is I will gladly fix it myself; however, I want to make sure this is intended functionality and not an accidental inclusion that might be fixed in future versions of PHP. Reproduce code: --------------- <?php function autoload($class) { throw new Exception('test'); require $class . '.php'; } spl_autoload_register('autoload'); try { new NoExist(); } catch (Exception $e) { echo 'unable to load the class.'; } Expected result: ---------------- Fatal error, as the autoloader throws an exception which is not allowed. Actual result: -------------- string of "unable to load the class." ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50250&edit=1
