Hi Johannes,

I double-checked the documentation and found no mention that the string
passed to class_exists() must be fully qualified. Perhaps this is a
documentation bug.

It is certainly seems inconsistent/counter-intuitive:-

class_exists('Things\Car'); // FALSE, class does not exist
$car = new Things\Car(); // HUH? Class does exist after all

So PHP is able to figure out there is a "use Foo/Things" namespace in
effect on one line, but not on the other? Lame.

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

When used as a string we need the fully qualified name as we don't know
where the parameter is coming from.

Description:
------------
class_exists() is not calling my spl_autoload_register'ed function with
a fully qualified (namespaced) class name.

Because the input to my autoload function is not fully qualified, it
cannot load the class and class_exists return false; however, if I try
to instantiate the class that "does not exist" then the correct, fully
qualified class now passed to the autoloader: it correctly loads the
class and my code works.

Reproduce code:
---------------
// register my autoloader

use Foo\Things;

// This fails: my autoload function is called with $class =
'Things\Car'
if(class_exists('Things\Car')){
    echo "class exists!";
}else{
    echo "Weird?";
}


// This works: my autoload function is called with $class =
'Foo\Things\Car'
$x = new Things\Car(); 



Expected result:
----------------
"class exists!"

Actual result:
--------------
"Weird?"
