What did the fix turn out to be?  I'm just starting out with phpwebsocket and 
am noticing the same issue.

Same issue. I see the following in my command prompt (with different numbers):

Warning: socket_select(): 5 is not a valid Socket resource

Even on the successful connections I see many of these warnings.

Found that the handshake sometimes (frequently?) fails.  This will lead to an 
invalid socket error.  Not clear on why the handshake is failing yet however.  
To see if this is what's causing you problems, set $debug on line 11 to true; 
this will get you more error logging in the console.

I found the error and a solution too.

Sometimes $numkey1 and/or $numkey2 are bigger than max int value. Therefore, a 
% b returns false values. The ints are replaces by floats, i.e. instead of a % 
b use fmod(a, b).

To the point: Change the if clause of console('failed') to:

if ($spaces1 == 0 || $spaces2 == 0 || fmod($numkey1, $spaces1) != 0 || 
fmod($numkey2, $spaces2) != 0) {
