Edit report at https://bugs.php.net/bug.php?id=63665&edit=1 ID: 63665 Updated by: dmitry@php.net Reported by: dev at jurajsplayground dot com Summary: Relative namespace import causes getClass() method to throw an exception -Status: Assigned +Status: Not a bug Type: Bug Package: Reflection related Operating System: Ubuntu PHP Version: 5.4.9 Assigned To: dmitry Block user comment: N Private report: N New Comment: PHP doesn't support *relative* namespace import. A name from "use" statement is always used as a full namespace name. Previous Comments: ------------------------------------------------------------------------ [2012-12-02 05:52:11] laruence@php.net I have tried to make a fix, but for such situation use \Foo; CG(current_import) only hold the Foo name but doesn't hold the global name flag.. so, I can not simply resolve the full name of a class name which is imported and in a namespace. ------------------------------------------------------------------------ [2012-12-02 05:22:58] laruence@php.net actually, this is not a only reflection specific issue. <?php namespace Foo\Bar\A\B; interface BInterface {} class Foo implements BInterface { } namespace Foo\Bar; use A\B\BInterface; class Bar implements BarInterface { public function __construct() { echo "Hello!"; } public function getSomething(BInterface $b){} } interface BarInterface { public function getSomething(BInterface $b); } namespace TestNamespace; use Foo\Bar\A\B; $obj = new \Foo\Bar\Bar(); $arg = new \Foo\Bar\A\B\Foo; $obj->getSomething($arg); PHP Catchable fatal error: Argument 1 passed to Foo\Bar\Bar::getSomething() must be an instance of A\B\BInterface, instance of Foo\Bar\A\B\Foo given, called in /tmp/1.php on line 30 and defined in /tmp/1.php on line 18 dmitry, could you please look at this one? ------------------------------------------------------------------------ [2012-12-01 23:10:49] dev at jurajsplayground dot com Description: ------------ While importing of namespaced classes via relative namespace directive works when creating objects, ReflectionParameter::getClass() has a problem with it and throws an exception that such class cannot be found. Test script: --------------- namespace Foo\Bar; use A\B\BInterface; class Bar implements BarInterface { public function __construct() { echo "Hello!"; } public function getSomething(BInterface $b){} } namespace Foo\Bar; use A\B\BInterface; interface BarInterface { public function getSomething(BInterface $b); } namespace Foo\Bar\A\B; interface BInterface {} namespace TestNamespace; $obj = new \Foo\Bar\Bar(); $ref = new \ReflectionMethod("\\Foo\Bar\Bar", "getSomething"); echo current($ref->getParameters())->getClass(); Expected result: ---------------- Should display interface information Actual result: -------------- ReflectionException is thrown: Class A\B\BInterface does not exist ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63665&edit=1
