当我添加socket_set_nonblock时，插座接受给出错误

Question

我的代码工作正常，但是当我更改并添加socket_set_nonblock（$ socket） socket_accept给我错误11时，这是我的

<?php
session_start();
require "checklogin.php";
error_reporting(0);
$user=$_SESSION["usr"];

set_time_limit(0);
ob_implicit_flush();
$host="127.0.0.1";
$port=11287;
$greeting="\nWelcome to my PHP server(listener)\nto quit type 'quit\nto shutdown the server type 'shutdown'.\n";

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP) or die("Err: " . socket_last_error());
socket_bind($socket, $host, $port) or die("Err: " . socket_last_error());
if (!socket_set_option($socket, SOL_SOCKET, SO_REUSEADDR, 1)) {}
$result = socket_listen($socket) or die("can't set up listener");
socket_set_nonblock($socket) or die("rip multiple: " . socket_last_error());
while (true) {
if ($spawn = socket_accept($socket) or die("err: can't accept - " . socket_last_error())) {
socket_write($spawn, $greeting, strlen($greeting));
}
do {

$input = socket_read($spawn, 1024, PHP_NORMAL_READ) or die("Could not read input\n");
socket_write($spawn, $user, strlen("needreload"));
echo $input . "<br>";



}
while (true);

socket_close($spawn);
}
socket_close($socket);
?>

11是eagain / ewoldblock，这意味着如果套接字'''socket' t明确设置为非阻滞。这正是将插座设置为非障碍物时所期望的错误，并且必须通过以后再尝试，理想情况下，请在选择文件描述符已准备好进行此操作。如果您不希望这种错误，则不要将插座设置为非阻滞。
