#50250 [Opn]: Exceptions can be thrown and caught in an autoload function

ID: 50250 Updated by: rquadling@php.net Reported By: brandon@php.net Status: Open Bug Type: Scripting Engine problem Operating System: Irrelevent PHP Version: 5.3.1 New Comment: 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. Previous Comments: ------------------------------------------------------------------------ [2009-11-20 20:14:30] bjori@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] brandon@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
