Tutorial not working


I downloaded the files from kirupa,

i was able to run.

When i publish as html and run it it’s not working. What should i have to do to make it run in browser.


One problem is that flash does not allow connections using sockets if the file is on the hard drive. A solution to this is to install a web server onto your computer and then place the html/flash files onto the web server. Then, it would work.

Annoying, but this is an attempt to have more security.


I ran it using webserver, its not working. All files are in same directory. I tried,
http://localhost/sockets/socketsTut.html as well as

But when i run directly from flash it works fine. Please help me out


It is working. I change it to instead of localhost.

Now i want the server to keep on sending some random data and whichever client connects should receive those data. At present only one client is able to get the data.

// E_ALL is a named constant (bit of 2047)
// error_reporting(E_ALL) ensures any errors will be displayed

// set_time_limit() is set to 0 to impose no time limit

//---- Function to Send out Messages to Everyone Connected ----------------------------------------
// $allclient is an array of resource id's that php will refer to for the sockets
// $socket contains the resource id for the flash client who sent the message
// $buf is just the message they sent, we are sending to everyone using a foreach loop

//---- Start Socket creation for PHP 5 Socket Server -------------------------------------

// socket_create function is pretty simple, depending on what you want it to do, you can just rig it for that,

// then socket_create takes and uses SOCK_STREAM, another default available socket type, 
// and uses a SOL_TCP protocol to have a guaranteed data sending.

// we want to be able to reuse our sockets, so we set our $master socket with a level at SOL_SOCKET, 
// with it reusable (SO_REUSEADDR), and a "1" in the mixed optval spot to make it true.
socket_set_option($master, SOL_SOCKET,SO_REUSEADDR, 1);

// now we need to bind our socket to the address and port specified.
if (($ret = socket_bind($master, $address, $port)) < 0) {

// to allow our socket server to listen for incoming calls made by our flash client, we need
// to use socket_listen on our $master socket. The next flag indicates that only 5 calls at a time.
// any others will be refused until there is sufficient room to process a new call.
if (($ret = socket_listen($master, 5)) < 0) {
