如何在等待套接字时实现PHP超时

Question

每隔60秒，我就想执行一些其他例程。在这次活动中，我也希望有机会重新建立连接，如果它失去了任何原因。如何做到这一点呢?

<?php
$sock = socket_create(AF_INET, SOCK_STREAM, 0);
socket_bind($sock, "123.321.123.321" , 20);
socket_listen ($sock , 10);
while (true) 
{
    //Do some other routine ever 60 seconds
    $client =  socket_accept($sock);  //Blocking function!
    $input = socket_read($client, 1024000);
    $response=processInput($input);
    socket_write($client, $response);
}

使用stream_select()函数

例如:

$socket = stream_socket_server("tcp://0.0.0.0:8160", $errno,$errorMessage);
$master[] = $socket;
$read = $master;
$write_something = false;
$mod_fd = stream_select($read, $_w, $_e, $write_something ? 0 : 1, 5000);
