php socket编程 读完成后写阻塞
server端代码 如下：
<br>
<?php<br>
set_time_limit(0);<br>
<br>
$host = "127.0.0.1";<br>
$port = 12345;<br>
<br>
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP) or die("Could not create socket\n"); // 创建一个Socket<br>
<br>
$result = socket_bind($socket, $host, $port) or die("Could not bind tosocket\n"); //绑定Socket到端口<br>
<br>
$result = socket_listen($socket) or die("Could not set up socket listener\n"); // 开始监听连接<br>
<br>
$spawn = socket_accept($socket) or die("Could not accept incoming connection\n"); // 处理通信<br>
<br>
//若换成循环接收数据，客户端将一直处理等待接收状态<br>
$input = socket_read($spawn, 1024) or die("Could not read data\n");<br>
/* <br>
while (( $data = socket_read($spawn, 1024)) != false) <br>
$input .= $data;<br>
*/ <br>
<br>
echo 'input:', strlen($input), "\n";<br>
<br>
$output = date("Y-m-d H:i:s"). "\n"; //处理客户端输入并返回结果<br>
<br>
echo "output:", $output, "\n";<br>
<br>
// 数据传送 向客户端写入返回结果<br>
socket_write($spawn, $output, strlen($output)) or die("Could not write output\n"); <br>
<br>
// 关闭sockets<br>
socket_close($spawn);<br>
socket_close($socket);
client端， 代码如下：
<br>
<?php<br>
<br>
set_time_limit(0);<br>
<br>
$host = "127.0.0.1";<br>
$port = 12345;<br>
<br>
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)or die("Could not create socket\n"); // 创建一个Socket<br>
<br>
$connection = socket_connect($socket, $host, $port) or die("Could not connet server\n"); // 连接<br>
<br>
socket_write($socket, "time") or die("Write failed\n"); // 数据传送 向服务器发送消息<br>
<br>
echo 'wait for data';<br>
<br>
while (($buffer = socket_read($socket, 1024))!=false) {<br>
echo("Data sent was: time\nResponse was:" . $buffer . "\n");<br>
}<br>
<br>
socket_close($socket);<br>
如果将server端对client read操作换成循环内部读取，则client会一直处于 wait data状态。
有办法让server端循环读的情况下，读完后给client写数据吗
socket
tcp
php
server
