I experienced the exact same issue on PHP 5.4.17 on OS X 10.9 (Mavericks DP6).
I wrote a simple test case, here it is :
Test script:
---------------
namespace jubianchi\Alias {
class A {}
var_dump(class_alias('\\jubianchi\\Alias\\A', 'C'));
$reflector = new \ReflectionClass('C');
var_dump($reflector->getName());
var_dump(class_alias('\\jubianchi\\Alias\\A', '\\jubianchi\\Alias\\B'));
try {
$reflector = new \ReflectionClass('\\jubianchi\\Alias\\B');
var_dump($reflector->getName());
} catch(\Exception $e) {
var_dump(get_class($e) . ': ' . $e->getMessage());
}
var_dump(class_alias('\\jubianchi\\Alias\\A', 'jubianchi\\Alias\\B'));
$reflector = new \ReflectionClass('\\jubianchi\\Alias\\B');
var_dump($reflector->getName());
}
Expected result:
----------------
bool(true)
string(17) "jubianchi\Alias\A"
bool(true)
string(17) "jubianchi\Alias\A"
bool(true)
string(17) "jubianchi\Alias\A"
Or:
----------------
bool(true)
string(17) "jubianchi\Alias\A"
bool(false)
string(60) "ReflectionException: Class \jubianchi\Alias\B does not exist"
bool(true)
string(17) "jubianchi\Alias\A"
Actual result:
----------------
bool(true)
string(1) "A"
bool(true)
string(17) "jubianchi\Alias\A"
bool(true)
string(60) "ReflectionException: Class \jubianchi\Alias\B does not exist"
bool(true)
string(17) "jubianchi\Alias\A"
As you can see, class_alias returns bool(true) as if everything went fine, so
we
expect the alias to be available but a reflection on the latter throws an
exception.
I think class_alias should be able to handle the leading backslashes or return
bool(false) if it can't.

Description:
------------
Aliasing namespaced classes currently expects that class names will be given in
the same form as the ZE uses internally; ie without a leading backslash. Since
that's inconsistent with the absolute form in PHP, it would be good if
class_alias() could also ignore a leading backslash.
Test script:
---------------
<?php
namespace A;
class C { function foo() { echo "42\n"; } }
namespace B;
class_alias('\A\C', '\B\C');
$c = new C;
$c->foo();
Expected result:
----------------
42
Actual result:
--------------
Fatal error: Class 'B\C' not found in /private/tmp/test.php on line 7
