#27440 [Bgs->Opn]: declare classes before usage

ID: 27440 Updated by: betz@php.net Reported By: holliwell at gmx dot net -Status: Bogus +Status: Open Bug Type: Class/Object related Operating System: linux 2.4.20 RH8 PHP Version: 5CVS-2004-02-29 (dev) New Comment: Reopen Previous Comments: ------------------------------------------------------------------------ [2004-03-09 19:58:55] holliwell at gmx dot net Iliaa, I did not get your point, sorry! 1.) In php5 its possible to do $c = new someclass , before someclass is defined, _without_ throwing an error. 2.) Wich error are you talking about: <qoute> since at the time the error is generated </qoute> 3.) be gentle ;-) and do not mark this bogus, at least a doc bug. Or change README.PHP4-TO-PHP5-THIN-CHANGES to reflect the current behaviour (which is not throwing an error in this case.) 4.) AFAIK at some stage of php5 using a class before declaring was throwing an fatal error. This was changed because of bc. So why should it be not possible in E_STRICT mode to throw a warning? Kind regards Friedhelm ------------------------------------------------------------------------ [2004-03-09 19:10:10] iliaa@php.net 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 In this case raising E_STRICT is not possible since at the time the error is generated the parser does not know if the class will be declared at a later point. This is just one of the PHP 5 <-> 4 incompatibilities that will need to be documented. ------------------------------------------------------------------------ [2004-02-29 18:53:11] holliwell at gmx dot net yup, so what about at least issue a warning with E_STRICT? ------------------------------------------------------------------------ [2004-02-29 18:42:36] derick@php.net It is required if you use inheritance and interfaces, so I think it should stay like this. declaring classes after using them is IMO not really nice (and afaik it can hurt some performance), so I think we should keep advising not to do this. ------------------------------------------------------------------------ [2004-02-29 18:35:22] holliwell at gmx dot net Description: ------------ Hi, README.PHP4-TO-PHP5-THIN-CHANGES states that classes must be declared before used. That seems no longer to be true. Reproduce code: --------------- <?php $test = new fubar(); $test->barfu(); class fubar { function barfu() { echo 'fubar'; } } ?> Expected result: ---------------- Fatal error: Class 'fubar' not found in .... Actual result: -------------- fubar ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=27440&edit=1
