an einen TCP/IP-Server über PHP-Skript Connecting

Question

Ich brauche einen PHP-Skript auf meiner Website zu implementieren, die folgende tun würden:

1. Verbindung zu einem Remote-Server
2. Senden Paket an den Server
3. Paket empfängt von dem Server

Alles schon auf der Serverseite konfiguriert ist, um Paketanforderungen reagieren zu können, brauche ich nur, um herauszufinden, wie pHP zu verwenden, um TCP/IP-Server zu verbinden.

Irgendwelche Ideen in welche Richtung zu schauen?

Answer 1

leicht mit PHP Buchsen verbinden:

<?php 
$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30); 
if (!$fp) { 
    echo "$errstr ($errno)<br />\n"; 
} else { 
    fwrite($fp, "You message"); 
    while (!feof($fp)) { 
     echo fgets($fp, 128); 
    } 
    fclose($fp); 
} 
?>

<?php 
error_reporting(E_ALL); 

/* Allow the script to hang around waiting for connections. */ 
set_time_limit(0); 

/* Turn on implicit output flushing so we see what we're getting 
* as it comes in. */ 
ob_implicit_flush(); 

$address = '192.168.1.53'; 
$port = 10000; 

if (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) === false) { 
    echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n"; 
} 

if (socket_bind($sock, $address, $port) === false) { 
    echo "socket_bind() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n"; 
} 

if (socket_listen($sock, 5) === false) { 
    echo "socket_listen() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n"; 
} 

do { 
    if (($msgsock = socket_accept($sock)) === false) { 
     echo "socket_accept() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n"; 
     break; 
    } 
    /* Send instructions. */ 
    $msg = "\nWelcome to the PHP Test Server. \n" . 
     "To quit, type 'quit'. To shut down the server type 'shutdown'.\n"; 
    socket_write($msgsock, $msg, strlen($msg)); 

    do { 
     if (false === ($buf = socket_read($msgsock, 2048, PHP_NORMAL_READ))) { 
      echo "socket_read() failed: reason: " . socket_strerror(socket_last_error($msgsock)) . "\n"; 
      break 2; 
     } 
     if (!$buf = trim($buf)) { 
      continue; 
     } 
     if ($buf == 'quit') { 
      break; 
     } 
     if ($buf == 'shutdown') { 
      socket_close($msgsock); 
      break 2; 
     } 
     $talkback = "PHP: You said '$buf'.\n"; 
     socket_write($msgsock, $talkback, strlen($talkback)); 
     echo "$buf\n"; 
    } while (true); 
    socket_close($msgsock); 
} while (true); 

socket_close($sock); 
?> 

this is just an example from net for further look documentation

TCP Server

$host="192.168.1.99"; 
    $port = 1234; // open a client connection 
    $fp = fsockopen ($host, $port, $errno, $errstr); 
    if (!$fp) { 
    $result = "Error: could not open socket connection"; 
    } 
    else { // get the welcome message fgets ($fp, 1024); // write the user string to the socket 
    fputs($fp, $message); // get the result $result .= fgets ($fp, 1024); // close the connection 
    fputs ($fp, "END"); 
    fclose ($fp); // trim the result and remove the starting ? 
    $result = trim($result); 
    $result = substr($result, 2); // now print it to the browser 
    } ?> 
    Server said: <? echo $result; ?>
