Bug #71983 [Nab]: Not clear namespace resolution

Edit report at https://bugs.php.net/bug.php?id=71983&edit=1 ID: 71983 User updated by: goetas at gmail dot com Reported by: goetas at gmail dot com Summary: Not clear namespace resolution Status: Not a bug Type: Bug Package: *General Issues PHP Version: 5.6.20 Assigned To: cmb Block user comment: N Private report: N New Comment: Ok, Thanks. It is clear now. Buy the documentation says that aliases are per file. But now it seems that they are per namespace. Is it? Previous Comments: ------------------------------------------------------------------------ [2016-04-09 11:25:58] cmb@php.net The second namespace declaration already defines a class C in namespace B, hence the error. You'd have to alias A\C, see <https://3v4l.org/g90NX>, for instance. ------------------------------------------------------------------------ [2016-04-07 16:03:56] goetas at gmail dot com Description: ------------ It is not possible to alias a class from a namespace. I have also tried placing classes in different files, but the problem persists. Test script: --------------- <?php namespace A { class C { } } namespace B { class C { } } namespace B { use A\C; echo "something"; } Expected result: ---------------- something Actual result: -------------- PHP Fatal error: Cannot use A\C as C because the name is already in use in /vagrant/A/run.php on line 12 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71983&edit=1
