New Comment:
Namespaces is a compile time feature. In run-time you should always use
full qualified names. You can use a special constant __NAMESPACE__ to do
it.
$classname2 = __NAMESPACE__ . '\foo\bar\Baz';

Description:
------------
When using a variable to instantiate a class, the behavior in namespace
resolving is inconsistent to the behavior when using a static class
name.
Reproduce code:
---------------
namespace foo\bar;
class Baz {
public $value;
public function __construct($v) {
$this->value = $v;
}
public function echoValue() {
echo 'Value: ' . $this->value, PHP_EOL;
}
}
$classname1 = '\foo\bar\Baz';
$classname2 = 'foo\bar\Baz';
$a = new $classname1('A');
$a->echoValue();
$b = new $classname2('B');
$b->echoValue();
$c = new \foo\bar\Baz('C');
$c->echoValue();
$d = new foo\bar\Baz('D');
$d->echoValue();
Expected result:
----------------
Value: A
Fatal error: Class 'foo\bar\foo\bar\Baz' not found in
/Users/tj/Documents/workspace/yeti/lib/yeti/NamespaceTest.php on line
20
Actual result:
--------------
Value: A
Value: B
Value: C
Fatal error: Class 'foo\bar\foo\bar\Baz' not found in
/Users/tj/Documents/workspace/yeti/lib/yeti/NamespaceTest.php on line
24
