Below code is my PHP CLi TCP server socket , but I try to make a TCP & UDP socket server or just udp server , but I don't know how can make it
MyCodes:
// PHP SOCKET SERVER
error_reporting(E_ERROR);
// Configuration variables
$host = "192.168.0.1";
$port = 5009;
$max = 20;
// MySQL Database Conf
$db_host ='localhost';
$db_user ='root';
$db_pass ='5222348';
$db_database ='gps';
mysql_connect("$db_host", "$db_user", "$db_pass")or die("################# Can't connet to mysql server");
mysql_select_db("$db_database")or die("################# Can't connet to database");
// --------------------------------
$client = array();
// No timeouts, flush content immediatly
set_time_limit(0);
ob_implicit_flush();
// Server functions
function rLog($msg){
$msg = "
echo($msg);
}
// Create socket
// $sock = socket_create(AF_INET,SOCK_DGRAM,0) or die("[".date('Y-m-d H:i:s')."] Could not create socket
"); UDP communication
$sock = socket_create(AF_INET,SOCK_STREAM,0) or die("[".date('Y-m-d H:i:s')."] Could not create socket
");
// Bind to socket
socket_bind($sock,$host,$port) or die("[".date('Y-m-d H:i:s')."] Could not bind to socket
");
// Start listening
socket_listen($sock) or die("[".date('Y-m-d H:i:s')."] Could not set up socket listener
");
rLog("
Server started at ".$host.":".$port."
rev:23-7-11:13");
// Server loop
while(true){
socket_set_block($sock);
// Setup clients listen socket for reading
$read[0] = $sock;
for($i = 0;$i<$max;$i++){
if($client[$i]['sock'] != null)
$read[$i+1] = $client[$i]['sock'];
}
// Set up a blocking call to socket_select()
$ready = socket_select($read,$write = NULL, $except = NULL, $tv_sec = NULL);
// If a new connection is being made add it to the clients array
if(in_array($sock,$read)){
for($i = 0;$i<$max;$i++){
if($client[$i]['sock']==null){
if(($client[$i]['sock'] = socket_accept($sock))<0){
rLog("socket_accept() failed: ".socket_strerror($client[$i]['sock']));
}else{
socket_getpeername($client[$i]['sock'], $address, $port);
rLog("Client #".$i." connected from : ".$address.":".$port."");
}
break;
}elseif($i == $max - 1){
rLog("Too many clients");
}
}
if(--$ready <= 0)
continue;
}
for($i=0;$i<$max;$i++){
if(in_array($client[$i]['sock'],$read)){
$input = socket_read($client[$i]['sock'],1024);
if($input==null){
unset($client[$i]);
}
$n = trim($input);
$com = split(" ",$n);
if($n=="EXIT"){
if($client[$i]['sock']!=null){
// Disconnect requested
socket_close($client[$i]['sock']);
unset($client[$i]['sock']);
rLog("Disconnected(2) client #".$i);
for($p=0;$p<count($client);$p++){
socket_write($client[$p]['sock'],"DISC ".$i.chr(0));
}
if($i == $adm){
$adm = -1;
}
}
}elseif($n=="TERM"){
// Server termination requested
socket_close($sock);
rLog("Terminated server (requested by client #".$i.")");
exit();
}elseif($input){
// ----------------------------------------- //
// $handle = fopen('inbox.txt', 'a+');
// fwrite($handle,
// $input."
".
// "------------------------------------------------------------
");
// ########################################################################################### //
// $input = "$POS,115316,160137.000,A,2719.9343,N,05310.5553,E,0.00,,180712,,,A/00000,00000/0,0,0,0/794"; // Sample Data
$input_first = explode(",", $input);
$frstvalue=$input_first[0]; // $POS - Command
echo $input;
$handle = fopen('force.log', 'a+');
fwrite($handle,
"Time:[".date('Y-m-d H:i:s')."] , from : ".$address.":".$port."
input: ".$input."
".
"-------------------------------------------------------------------------------------
");
###########################
}
}else{
//}
}
}
}
// Close the master sockets
socket_close($sock);
above codes is work perfectly on TCP connections , but can't give UDP requests .
