PHP socket Listening loop
提问by Dest
With the following code, I can receive 1 request and write it:
使用以下代码，我可以接收 1 个请求并编写它：
function listen()
{
// Set time limit to indefinite execution
set_time_limit (0);
// Set the ip and port we will listen on
$address = 'XX.XX.XX.XXX';
$port = XXXX;
// Create a TCP Stream socket
$sock = socket_create(AF_INET, SOCK_STREAM, 0);
// Bind the socket to an address/port
$bind = socket_bind($sock, $address, $port);
// Start listening for connections
socket_listen($sock);
/* Accept incoming requests and handle them as child processes */
$client = socket_accept($sock);
// Read the input from the client – 1024 bytes
$input = socket_read($client, 2024);
// Strip all white spaces from input
echo $input;
// Close the master sockets
$close = socket_close($sock);
var_dump($close);
}
listen();
But it close automatically listening once it received 1 packet. I need to keep receiving packets until an exit or any close command is received.
但是一旦收到 1 个数据包，它就会自动关闭侦听。我需要继续接收数据包，直到收到退出或任何关闭命令。
How should I go about changing the code above to make this function into a loop?
我应该如何更改上面的代码以使这个函数成为一个循环？

set_time_limit (0);
$address = '46.49.41.188';
$port = 7777;
$con = 1;
$word = "";
$sock = socket_create(AF_INET, SOCK_STREAM, 0);
$bind = socket_bind($sock, $address, $port);
socket_listen($sock);
while ($con == 1)
{
$client = socket_accept($sock);
$input = socket_read($client, 2024);
if ($input == 'exit')
{
$close = socket_close($sock);
$con = 0;
}
if($con == 1)
{
$word .= $input;
}
}
echo $word;
If request will be exit listening will closed. That method was tested :) and it works.
如果请求将退出监听将关闭。该方法已经过测试:)并且它有效。

How about:
怎么样：
function listen(){
// Set the ip and port we will listen on
$address = 'XX.XX.XX.XXX';
$port = XXXX;
// Create a TCP Stream socket
$sock = socket_create(AF_INET, SOCK_STREAM, 0);
// Bind the socket to an address/port
$bind = socket_bind($sock, $address, $port);
// Start listening for connections
socket_listen($sock);
/* Accept incoming requests and handle them as child processes */
$client = socket_accept($sock);
// Read the input from the client – 1024 bytes
$input = socket_read($client, 2024);
// Strip all white spaces from input
echo $input;
// Close the master sockets
$close = socket_close($sock);
var_dump($close);
listen();
}
set_time_limit (0);
listen();
