The exception can be caught inside the autoloader function: function __autoload($className) { if($className == 'Foo') { class Foo implements Bar {} } else { try { throw new Exception('message'); } catch(Exception $ex) {} } } new Foo; this code produces a fatal error: Fatal error: Interface 'Bar' not found in bug.php on line 5 ------------------------------------------------------------------------ [2009-10-19 10:06:18] jani@php.net Only crashes when the interface "Bar" is no defined. ------------------------------------------------------------------------ [2009-10-18 10:19:51] sjoerd@php.net Could reproduce with php 5.3-head. Backtrace: http://pastebin.com/f35c15146 ------------------------------------------------------------------------ [2009-10-17 13:31:30] fqqdk at freemail dot hu Description: ------------ PHP crashes with the below code: Reproduce code: --------------- function __autoload($className) { if($className == 'Foo') { class Foo implements Bar {}; } else { throw new Exception; } } new Foo; Expected result: ---------------- I don't know what to expect. The manual says, that you can't catch an exeption thrown in an autoload function, but the crash only happens when the autoload function gets called the second time. Below code doesn't crash, but instead produces a Fatal error: function __autoload($className) { throw new Exception; } new Foo; Actual result: -------------- Faulting application php.exe, version 5.3.0.0, faulting module php5ts.dll, version 5.3.0.0, fault address 0x0002358a. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=49908&edit=1
