php实现socket的服务端和客户端示例

服务端

<?php 
$socket = stream_socket_server("tcp://0.0.0.0:8000", $errno, $errstr);
if (!$socket) {
  echo "$errstr ($errno)<br />
";
} else {
  while ($conn = stream_socket_accept($socket)) {
    fwrite($conn, "Content-Type: text/plain

");
    fwrite($conn, "hello socket
");
    fclose($conn);
  }
  fclose($socket);
}
?>

客户端

<?php
$fp = stream_socket_client("tcp://127.0.0.1:8000", $errno, $errstr, 30);
if (!$fp) {
    echo "$errstr ($errno)<br />
";
} else {
    while (!feof($fp)) {
        echo fgets($fp, 1024);
    }
    fclose($fp);
}
?>
