4.function.php 统计数据页面
<?php
//统计在线人数
function clearDir($dir)
{
$n = 0;
if ($dh = opendir($dir))
{
while (($file = readdir($dh)) !== false)
{
if ($file == '.' or $file == '..')
{
continue;
}
if (is_file($dir . $file)) {
$n++;
}
}
}
closedir($dh);
return $n;
}
//通知在线的人
function notice($dir){
if ($dh = opendir($dir))
{
while (($file = readdir($dh)) !== false)
{
if ($file == '.' or $file == '..')
{
continue;
}
if (is_file($dir . $file)) {
$array[]=file_get_contents($dir.$file);
}
}
}
closedir($dh);
return $array;
}
5.在同级目录下建立client文件，存放信息
PHP 即使通讯
1.socket.php 一样，使用时需要开启
<?php
//创建websocket服务器对象，监听0.0.0.0:9502端口
$ws = new swoole_websocket_server("0.0.0.0", 9502);
//监听WebSocket连接打开事件
$ws->on('open', function ($ws, $request) {
$fd[] = $request->fd;
$GLOBALS['fd'][] = $fd;
//$ws->push($request->fd, "hello, welcome\n");
});
//监听WebSocket消息事件
$ws->on('message', function ($ws, $frame) {
$msg = 'from'.$frame->fd.":{$frame->data}\n";
//var_dump($GLOBALS['fd']);
//exit;
foreach($GLOBALS['fd'] as $aa){
foreach($aa as $i){
$ws->push($i,$msg);
}
}
// $ws->push($frame->fd, "server: {$frame->data}");
// $ws->push($frame->fd, "server: {$frame->data}");
});
//监听WebSocket连接关闭事件
$ws->on('close', function ($ws, $fd) {
echo "client-{$fd} is closed\n";
});
$ws->start();
