Comment (by jcjcc):

 Try this

 {{{
 spl_autoload_extensions('.php');
 spl_autoload_register();

 var_dump(class_exists('Testing'));
 var_dump(class_exists('\\Testing\\Foo'));
 }}}

 I agree that at this point, it seems like a PHP bug.

 Apologies for claiming that class_exists was documented to throw an
 exception -- I did remember reading about the exception-throwing behavior
 in the docs, but it was in a comment, and not in the doc itself.

 If it doesn't throw any errors when you call
 {{{
 spl_autoload_register('spl_autoload');
 }}}
 but it does when you call
 {{{
 spl_autoload_register();
 }}}
 then this is strange behavior to me as well. Can you get back to me on
 whether that happens? Let's leave it at that then after that.

 Thanks rmccue, Denis-de-Bernardy, and SergeyBiryukov for your responses!
