PHP套接字客户端没有返回完整响应
我有一个Python套接字服务器和一个PHP套接字客户端。客户端向服务器发送命令，然后在页面上显示响应。它几乎可以一直运行。现在我遇到的问题是，当涉及到长时间的回应时，回应似乎被削减了。PHP套接字客户端没有返回完整响应
它不是Python服务器，因为您通过Telnet获得完整响应。这是PHP脚本的东西，我不能为我的生活，搞清楚。从远程登录

我搜索周围的几个星期和尝试了一切，但找不出解决问题。
下面是这一切背后的PHP脚本：
public function send($cmd, $host, $port, $timeout = 1.5){ // Get time of function start
$startTime = time();
//Try to create a socket
if(!($socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)))
{
$errorcode = socket_last_error();
$errormsg = socket_strerror($errorcode);
//If failed, die with error. (Check docs)
die("Error (#300)");
}
if(!socket_set_nonblock($socket)){
die("Error (#301)");
}
while([email protected]_connect($socket, $host, $port)){
if ((time() - $startTime) >= $timeout){
die("Error (#302)");
}
continue;
}
if(!socket_set_block($socket)){
die("Error (#303)");
}
if(!socket_write($socket, $cmd, strlen($cmd)))
{
$errorcode = socket_last_error();
$errormsg = socket_strerror($errorcode);
die("Error (#304)");
}
$reply = socket_read($socket, 16384)
or die("Error (#305)");
socket_close($socket);
return $reply;
}
如果有人知道如何解决这个问题，请帮助我。
在此先感谢！
回答：
您应该测试socket_write()的返回值是否发送的数据量与发送的数据量相同，即strlen($cmd)字节。如果不是这种情况，则将其余的写入套接字，直到发送完所有数据为止。
从socket_write()的文档：
socket_write（）不一定写从给定的缓冲器中的所有字节。根据网络缓冲区等的不同，只有一定数量的数据（即使是一个字节）被写入，尽管缓冲区更大，这是有效的。你必须小心，这样你才不会无意中忘记传输其余的数据。
