From: Operating system: OS X, FreeBSD PHP version: 5.3.2 Package: Scripting Engine problem Bug Type: Bug Bug description:implemeting an interface causes class not found
Description: ------------ Normally you can declare classes in any order inside of a php file. 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 bug report at http://bugs.php.net/bug.php?id=51395&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=51395&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=51395&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=51395&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=51395&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=51395&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=51395&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=51395&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=51395&r=needscript Try newer version: http://bugs.php.net/fix.php?id=51395&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=51395&r=support Expected behavior: http://bugs.php.net/fix.php?id=51395&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=51395&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=51395&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=51395&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=51395&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=51395&r=dst IIS Stability: http://bugs.php.net/fix.php?id=51395&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=51395&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=51395&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=51395&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=51395&r=mysqlcfg
