socket connection code of php

I am writing a simple php socket code.
Here is my code

 <?php

    $address="127.0.0.1";
    $port=9875;
    echo "I am here";

    if(false==($socket=  socket_create(AF_INET,SOCK_STREAM, SOL_TCP)))
    {
        echo "could not create socket";
    }
    socket_bind($socket, $address, $port) or die ("could not bind socket");
    socket_listen($socket);
    if(($client=socket_accept($socket)))
        echo "client is here";

    ?>

when I run this program my browser only shows waiting for localhost.
Is there any problem in my code?
I am using xammp 1.7.4 .
Another thing I want to know if I want to get a HTTP or FTP request do I have change only the port number?

Answer

I verified the code and tested in my system and it works correctly. Showing as “client is here” after running the client.

File Name: server.php

<?php
    $address="127.0.0.1";
    $port=9875;
    echo "I am here";
    set_time_limit (0); 
    if(false==($socket=  socket_create(AF_INET,SOCK_STREAM, SOL_TCP)))
    {
        echo "could not create socket";
    }
    socket_bind($socket, $address, $port) or die ("could not bind socket");
    socket_listen($socket);
    if(($client=socket_accept($socket)))
        echo "client is here";

    socket_close($socket); 
    ?>

First run the server.php file.

File: client.php

<?php
$host="127.0.0.1" ;
$port=9875;
$timeout=30;
$sk=fsockopen($host,$port,$errnum,$errstr,$timeout) ;
if (!is_resource($sk)) {
    exit("connection fail: ".$errnum." ".$errstr) ;
} else {

    echo "Connected";
    }
?>

Now run the client.php

Your output should be like this (as I got in my system)

I am hereclient is here

If not, make sure your firewall is not blocking the request. Temporarily disable antivirus if you have one.
