Edit report at http://bugs.php.net/bug.php?id=51395&edit=1 ID: 51395 Updated by: johannes@php.net Reported by: johnston dot joshua at gmail dot com Summary: implemeting an interface causes class not found -Status: Open +Status: Bogus Type: Bug Package: Scripting Engine problem Operating System: OS X, FreeBSD PHP Version: 5.3.2 New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php This is a documented limitation of the object implementation and the way we do object binding.

When one of your classes implements an interface, php will throw a fatal error about class not found if the class is declared in the wrong order. If you remove the implements clause then order does not matter. php bug http://bugs.php.net/bug.php?id=39758 also shows this and the reply from dmitry was: PHP always declares classes those implement interfaces at run-time. So in your example you cannot declare "Bar" because "Foo" is not declared yet. Your report may be categorised as "feature request", but it cannot be fixed in 5.2.* anyway, because of binary compatibility. Just because the internals handle things in a certain order does not mean that php should exhibit contradicting behavior based on valid class definitions. Test script: --------------- test.php <?php class One extends Two {} interface Three {} class Two implements Three {} ?> test2.php <?php class One extends Two {} interface Three {} class Two {} ?> Expected result: ---------------- test.php: no output test2.php: no output Actual result: -------------- jjohnston:~$ php test.php PHP Fatal error: Class 'Two' not found in /Users/jjohnston/test.php on line 2 Fatal error: Class 'Two' not found in /Users/jjohnston/test.php on line 2 jjohnston:~$ php test2.php ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=51395&edit=1
