phpを使用したWebSocketサービスの作成

実行方法:
まずserver.phpとindex.htmlのipを変更します
コマンドラインで実行 [phpパス]php.exe [[ファイルパス]server.php]
ブラウザでindex.htmlを開きます
server.php

'192.168.0.200',
  'port'=>'8000',
  'event'=>'WSevent',//        
  'log'=>true,
);
$websocket = new websocket($config);
$websocket->run();
function WSevent($type,$event){
  global $websocket;
    if('in'==$type){
      $websocket->log('    id:'.$event['k']);
    }elseif('out'==$type){
      $websocket->log('    id:'.$event['k']);
    }elseif('msg'==$type){
      $websocket->log($event['k'].'  :'.$event['msg']);
      roboot($event['sign'],$event['msg']);
    }
}
 
function roboot($sign,$t){
  global $websocket;
  switch ($t)
  {
  case 'hello':
    $show='hello,GIt @ OSC';
    break;  
  case 'name':
    $show='Robot';
    break;
  case 'time':
    $show='    :'.date('Y-m-d H:i:s');
    break;
  case '  ':
    $show='( ^_^ )/~~  ';
    $websocket->write($sign,'Robot:'.$show);
    $websocket->close($sign);
    return;
    break;
  case '     ':
    $array = array('     ','     ','     ');
    $show = $array[rand(0,2)];
    break;
