php socket 的问题

[qq85168163]

折腾两天了，望大神们指点：

一下是代码，可以发送socket，服务器端能收到，可是用socket_read接收服务器返回来的消息时就卡在这里了，什么原因呢。。。。

<?php

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); 
$connection = socket_connect($socket,'192.168.0.34', 6003); 
// Write some test data to our socket
$msg = file_get_contents('client4', 'r');//获取一个二进制文件内容
if(!socket_write($socket, $msg))
{
echo("<p>Write failed</p>"); 
} 
// Read any response from the socket
while($buffer = socket_read($socket, 1))
{
	//把接收的内容写入名为get4的文件----这个文件没生成
	$fp = fopen('get4','w');
	fwrite($fp,$buffer);
	fclose($fp);
	echo("<p>Data sent was: SOME DATA<br> Response was:" . $buffer . "</p>"); 
	break; //执行一次跳出
} 
echo("<p>Done Reading from Socket</p>"); 
?>

你把代码 if(!socket_write($socket, $msg)) 改为 if(!socket_write($socket, $msg,strlen($msg))) 试试。 如果还是卡。建议你使用strace -p 服务器端进程号。 会有输出内容，贴出来。帮你分析下

看下阻塞模式

你端口是不是被阻塞了

为何在循环内open write close？那不是不断在IO么？ send后sleep几秒试试
