PHP Warning: socket_select(): 9 is not a valid Socket resource

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
1. sudo php -q server.php
2. 192.168.1.15/client.html
3. refresh chrome explorer some times

What is the expected output? What do you see instead?
Stay connected to the chat.
Some times it disconnects from the chat, and on the server side it shows 
messages
PHP Warning:  socket_select(): 6 is not a valid Socket resource in 
/var/www/websocket/server.php on line 15
PHP Warning:  socket_select(): 7 is not a valid Socket resource in 
/var/www/websocket/server.php on line 15

/var/www/websocket/server.php on line 15
PHP Warning:  socket_select(): 11 is not a valid Socket resource in 
/var/www/websocket/server.php on line 15

What version of the product are you using? On what operating system?
Downloadad client.php and server.php from project home 13th June
Server side Ubuntu 11 + Apache2 + PHP5
Client side Windows XP SP3 + Chrome 12

Please provide any additional information below.
I haven't checked the code yet, as it's my first time working with sockets.

with these changes the application was running.

-$master=WebSocket("localhost",12345);
+$master=WebSocket("0.0.0.0",12345);

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

-$r=$h=$o=null;
+$r=$h=$o=$key1=$key2=$data=null; 

only strange action on disconect, I will check the code for my own application.

Strange behaviour:

I am testing completely on localhost but on two PCs
both: WindowsXP,SP3 - nginx1.0, php5.3.3, chrome14
One works always, one doesn't - all the time. I am
confused now.

GoogleCodeExporter commented 9 years ago

Sorry if I confused you also: each of my environments 
are chromebrowser and server nginx+php in each case on
one machine. One server-client-windows works always, the
other never. All files/setups etc are cloned (via dropbox)
and therefore are similar. I can't find a significant 
difference.. but I will tell you, if I find it..

I see that the now, the websocket headers are like this:

GET / HTTP/1.1
Upgrade: websocket
Connection: Upgrade
Host: www.xxxxxx.com:12345
Sec-WebSocket-Origin: http://www.xxxxxxxxx.com
Sec-WebSocket-Key: kYuC/SdNC0WoNCLLTm/sZA==
Sec-WebSocket-Version: 8

Only one key, no more key1 and key2.

How I do the handshake?

Additional from me: The difference between my two 
setups (see above) is Chrome13 on  the working PC
and Chrome14 on the never working one. I upgraded
to Chrome14  on the first setup and now  both are
never working.. 

So I googled that Chrome14 (and15) implements the
"ietf-hybi-10" spec  and  Chrome13 is using  some
older spec.  I think the handshake is now working
some different.. (?)

I'm running on XAMPP 1.7.1 on Windows 7.
I did all the changes mentioned above, in my file "server.php"
But the error is still recurring. Help, please!

GoogleCodeExporter commented 9 years ago

Well the quick answer is available but spread in this project home. The HTTP 
connection string slightly changed and Google Chrome changed this AFAIK in 
version 14 as well. Therefore all (well almost all) examples concerning 
WebSockets are no longer working. Comment 4 in Issue 35 is providing the new 
version of the HTTP protocol as well a possible implementation of the newly 
introduced sub-protocol.

Issue Details:
http://code.google.com/p/phpwebsocket/issues/detail?id=35#c4

The new protocol / sub-protocol explained in the current draft:
http://tools.ietf.org/html/draft-ietf-hybi-thewebsocketprotocol-17#section-5

client.php, it prints this message in chatbox

WebSocket - status 0
Disconnected - status 3

And on command line, getting these errors,

Notice: Undefined variable: key1 in D:\xampp\htdocs\socket\server.php on line 
143
Notice: Undefined variable: key2 in D:\xampp\htdocs\socket\server.php on line

I am using windows with xampp PHP 5.3.8 on both client and server side

I am running PHP 5.4.1 on Windows 7 64bit.
I downloaded the code as it is now and ran this in command line from the 
phpwebsocket folder:
php server.php
This is what I get:
Server Started : 2012-05-29 15:30:37

Listening on   : localhost port 12345

Then I open the client in Chrome 19.0.1084.52
I get this in the browser:
WebSocket - status 0
Disconnected - status 3

In the command line I see:

What can we do to fix this. Is it an updated php problem?

Same issue here. I tried with the suggested solution posted by on comment #1 
but the problem did  persist.

Any known reason for this?

Apparently upon debugging I found that whenever I get "Warning: 
socket_select(): 5 is not a valid Socket resource" error, the number that is 
printed out is the resource id of the socket.  Maybe the socket_accept is not 
creating a valid socket resource?

Any solutions for the "...is not a valid Socket resource in..." "...on line 
15..." ?  I am not quite sure what needs to be changed in order for the demo to 
work out of the box.

I also got these problems but with the changes it worked fine on localhost. 
Only if I want to access the script with my other computer it appears again in 
console and I get "disconnected - status 3". Can't find any reason/solution...
