hi there..
i have written a socket code which is not running and giving a warning that Socket_bind() unable to bind address.. can not assign requested address...
note:.. i am runing this code on a linux machine version 7.3.. so if it would need to enable some kind of sockets in its configuration file. then please tell me the name of that file also..
the code is attached..please have a look and do tell me its solution..
usman.
<?php
// set some variables
$host = "192.20.4.1";
$port= 3740;
// don't timeout1
set_time_limit(0);
//Create Socket
$socket= socket_create(AF_INET, SOCK_STREAM,SOL_TCP) or die ("could not create socket\n");
// bind socket to port
$result= socket_bind($socket,$host,$port) or die ("could not bind to socket\n");
// strat listenning to connections
$result=socket_listen($socket,3) or die ("could not set up socket listener\n");
//accept incomming connections
// spawn another socket to handle communication
$spawn= socket_accept($socket) or die ("could not accept incomming connection\n");
//read client input
$input= socket_read($spawn,1024) or die ("could not read input\n");
//Cleanup inout string
$input= trim($input);
//reverse client inout and send back
$output=strrev($input) . "\n";
socket_write($spawn,$output,strlen($output)) or die ("could not write output\n");
//close sockets
socket_close($spawn);
socket_close($socket);
?>
