Description:
------------
spl_autoload_extensions() accepts a string with a , separated list of
filename parts to register for autoloading.
This results in filenames containing a , as an extension filename
become impossible to register.
It should be possible to pass an array to circumvent any restriction
cased by the string based argument.

I know that ppl might consider it strange to use , as part of a
filename.

IMHO there may be cases where it might be necessary. Considering that
arrays are a native PHP data type, it would be a better design.

Reproduce code:
---------------
spl_autoload_extensions(array('.class.php', '.php'));
myclass::hello();

Expected result:
----------------
Hello world

Actual result:
--------------
Warning: spl_autoload_extensions() expects parameter 1 to be string,
array given in [test.php] on line ## 
Fatal error: Class 'myclass' not found in [test.php] on line ##

Using implode() would really be enough here, I'm not sure whether we should add that option or not, but it is indeed not a bad idea.

As a workaround you may want to do:
spl_autoload_extensions(implode(',', $extensions));

This is not about that I have a list of extensions in an array and that I am
unable to use implode to pass this to spl_autoload_extension() as a string.

This bug report is about that the design of spl_autoload_extension() would be
better if it accepts an array.
Using a whatether separated string implies that the whatether character can't be
a valid part of the argument list. An array does not have this limitation.

At this point in time, it may be more appropriate to deprecate
spl_autoload_extension() and spl_autoload().  If you, or anybody
else, is still interested in this feature, please forward the
request to the internals mailing list for discussion.  For the
time being, I'm suspending this ticket.
