我是 PHP 套接字编程的新手,我找到了一个可以试验的例子,但是当我与我的服务器交谈时,在服务器套接字关闭之前需要一分钟才能得到响应。
我有以下代码:SERVER.php
<?php
$host = "127.0.0.1";
$port = 1234;
// 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);
// 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);
?>
如何让它立即响应?谢谢
当我在终端中运行客户端代码时,我会立即得到响应。但是,当我添加一个文本框以从浏览器运行它时,只需 1 分钟即可在我的浏览器上显示响应。
如果你需要看看我的 CLIENT.php 这里是......
<html>
<head>
</head>
<body>
<form action="<? echo $PHP_SELF; ?>" method="post">
Enter some text:<br>
<input type="Text" name="message" size="15"><input type="submit" name="submit" value="Send">
</form>
<?php
if (isset($_POST['submit']))
{
// form submitted
// where is the socket server?
$host="127.0.0.1";
$port = 1234;
// open a client connection
$fp = fsockopen ($host, $port, $errno, $errstr);
if (!$fp)
{
$result = "Error: could not open socket connection";
}
else
{
// get the welcome message
fgets ($fp, 1024);
// write the user string to the socket
fputs ($fp, $_POST['message']);
// get the result
$result .= fgets ($fp, 1024);
// close the connection
fputs ($fp, "exit");
fclose ($fp);
// trim the result and remove the starting ?
$result = trim($result);
// now print it to the browser
}
?>
Server said: <b><? echo $result; ?></b>
<?
}
?>
</body>
</html>
