我正在制作服务器应用程序，在该应用程序中我需要向所有连接的用户广播消息。我创建了以下三个文件。
1)socketServer.php(工作正常)
2)index.html(工作正常)
3)notification.php(此文件中的问题)
notification.php(创建问题)
<?php
$post_data = json_encode(array('message'=>'Please refresh your page.'));
$socket = fsockopen("192.168.10.107", 9000, $errno, $errstr, 15);
if(!$socket){
echo ' error: ' . $errno . ' ' . $errstr;
die;
}else{
$http = "POST /myapp/socketTrigger.php HTTP/1.1\r\n";
$http .= "Host: 192.168.10.107\r\n";
$http .= "User-Agent: " . $_SERVER['HTTP_USER_AGENT'] . "\r\n";
$http .= "Content-Type: application/x-www-form-urlencoded\r\n";
$http .= "Content-length: " . strlen($post_data) . "\r\n";
$http .= "Sec-WebSocket-Key: gjdsjh8^8==Hjhdsur\r\n";
$http .= $post_data . "\r\n\r\n";
fwrite($socket, $http);
$contents = "";
while (!feof($socket)) {
$contents .= fgets($socket, 1024);
}
fclose($socket);
}
?>

最佳答案
您的解决方案不正确且合乎逻辑。您最为用户创建消息表，并且要发送广播消息时，仅在消息表上创建新记录，并且在客户端，客户端电话或Web应用程序中，大多数情况下(例如每10秒)检查一次该表
关于php - 使用php套接字向所有连接的客户端发送广播消息，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/47632783/
