First try my patch: http://pecl.php.net/bugs/bug.php?id=9349
and then use "objects" like:
$a = new Spread();
$a->connect("4803");
$a->join("group");

Hi, 

After applying the patch, and using OOP instead of procedural function calling, I've receive the following warning:

PHP Warning:  Spread::join(): SP_Join: expect groups to an array of strings or a string in /home/test/test.php on line 6

Source:

<?

$a = new Spread ();

$a->connect ("4803@192.168.0.8");
$a->join ("test");

?>

This bug has been fixed in CVS.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.
 
Thank you for the report, and for helping us make PECL better.
