Description:
------------
spl_autoload_functions() doesn't return the names of lambda-functions registered with spl_autoload_register() correctly. Actually it always returns '__lambda_func' for every lambda function so you can't use the result with spl_autoload_unregister() for example.

Test script:
---------------
<?php

function f1($class) { echo "f1: [[$class]]\n"; }
function f2($class) { echo "f2: [[$class]]\n"; }

spl_autoload_register('f1');
spl_autoload_register('f2');
spl_autoload_register(create_function('$class', 'echo "cf1: [[$class]]\n";'));
spl_autoload_register(create_function('$class', 'echo "cf2: [[$class]]\n";'));

var_dump(spl_autoload_functions());
foreach (spl_autoload_functions() AS $func)
{
	spl_autoload_unregister($func);
}
var_dump(spl_autoload_functions());

?>


Expected result:
----------------
All autoload functions are unregistered

Actual result:
--------------
lambda functions aren't unregistered

I have made a patch for this, but there is a BC break, that is, 
spl_autoload_functions return lambad_function with name "__lambad_function" 
previously.

after patched, it will return string like "lambad_1".

Is there a reason, why this fix still hasn't been implemented?

I'd like to see this bug fixed in PHP 5.5

David, what about this change on 5.5?
 [2013-06-25 05:18 UTC] laruence@php.net 
hmm, thanks for the reminding, I'd like to see this could happen in 5.5

@dsp, what do you think?

It looks like the fix for this has caused a build failure (Linux, armhf):

make: *** [ext/spl/php_spl.lo] Error 1

Investigating, but I may kick this back to Stas or Laruence if needed.

Fixed by expanding the ZEND_STRL macro call, since strncmp() is itself a macro on 
armhf Linux: http://git.php.net/?p=php-
