# EventHttp::accept

(PECL event >= 1.2.6-beta)

EventHttp::accept — Makes an HTTP server accept connections on the specified socket stream or resource

### 说明

public EventHttp::accept( mixed `$socket` ): bool

Makes an HTTP server accept connections on the specified socket stream or resource. The socket should be ready to accept connections.

Can be called multiple times to accept connections on different sockets.

> 注意:

> To bind a socket, `listen`, and `accept` connections on the socket in a single call use EventHttp::bind(). EventHttp::accept() is needed only if one already has a socket ready to accept connections.

### 参数

`socket`

  Socket resource, stream or numeric file descriptor representing a socket ready to accept connections.

### 返回值

成功时返回 `true`， 或者在失败时返回 `false`。

### 示例

示例 #1 EventHttp::accept() example

`<?php
$base = new EventBase();
$http = new EventHttp($base);
$addresses = [
8091 => "127.0.0.1",
8092 => "127.0.0.2",
];
$i = 0;
$socket = array();
foreach ($addresses as $port => $ip) {
echo $ip, " ", $port, PHP_EOL;
$socket[$i] = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if (!socket_bind($socket[$i], $ip, $port)) {
exit("socket_bind failed\n");
}
socket_listen($socket[$i], 0);
socket_set_nonblock($socket[$i]);
if (!$http->accept($socket[$i])) {
echo "Accept failed\n";
exit(1);
}
++$i;
}
$http->setCallback("/some-page", function () {
echo "(some-page)\n";
echo "URI: ", $req->getUri(), PHP_EOL;
$req->sendReply(200, "OK");
echo "OK\n";
});
$http->setDefaultCallback(function ($req) {
echo "URI: ", $req->getUri(), PHP_EOL;
$req->sendReply(200, "OK");
echo "OK\n";
});
$signal = Event::signal($base, SIGINT, function () use ($base) {
echo "Caught SIGINT. Stopping...\n";
$base->stop();
});
$signal->add();
$base->dispatch();
echo "END\n";
// We didn't close sockets, since Libevent already sets
// CLOSE_ON_FREE and CLOSE_ON_EXEC flags on the file
// descriptor associated with the sockets.
?>`

以上示例的输出类似于：

    Client:
    $ nc 127.0.0.1 8091
    GET /about HTTP/1.0
    Connection: close

    HTTP/1.0 200 OK
    Content-Type: text/html; charset=ISO-8859-1
    Connection: close

    Server:
    127.0.0.1 8091
    127.0.0.2 8092
    URI: /about
    OK
