套接字编程跨平台（PHP和Javascript）
我用PHP创建了一个套接字服务器，代码如下 PHP套接字编程跨平台（PHP和Javascript）,javascript,php,sockets,Javascript,Php,Sockets,我用PHP创建了一个套接字服务器，代码如下 PHP function listen() { // set some variables $host = "127.0.0.1"; $port = 25003; // don't timeout! set_time_limit(0); // create socket $socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create so
function listen()
{
// set some variables
$host = "127.0.0.1";
$port = 25003;
// don't timeout!
set_time_limit(0);
// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");
// bind socket to port
$result = socket_bind($socket, $host, $port) or die("Could not bind to socket\n");
// start listening for connections
$result = socket_listen($socket, 3) or die("Could not set up socket listener\n");
// accept incoming connections
// spawn another socket to handle communication
$spawn = socket_accept($socket) or die("Could not accept incoming connection\n");
// read client input
$input = socket_read($spawn, 1024) or die("Could not read input\n");
// clean up input string
$input = trim($input);
echo "Client Message : " . $input."\n";
// reverse client input and send back
$output = strrev($input) . "\n";
socket_write($spawn, $output, strlen($output)) or die("Could not write output\n");
// close sockets
socket_close($spawn);
socket_close($socket);
listen();
}
set_time_limit(0);
listen();

第二个参数是什么？这是否连接到我的php文件？因为我试图定位到我的php，它不工作。php套接字服务器正常，问题是Javascript，它正在发送HTTP请求，而此发送是HTTP协议 您可以在该端口上启动PHPWeb服务器，并在Ajax查询时回答该问题 命令行以像Web服务器一样启动php
php -S 127.0.0.1:25003
Web服务器的文档根与PHP相同我已经启动了PHP，但是如何从js创建请求？我的web套接字初始化是否正确？像这样的
新WebSocket（“ws://localhost:25003/server.php”）如果你想测试和学习WebSockets，也许你需要一些类似的socketo.me/docs，Misyaath Mohammed的回复有一个有用的链接。
php -S 127.0.0.1:25003
