EventHttp::accept
(PECL event >= 1.2.6-beta)
EventHttp::accept — Makes an HTTP server accept connections on the specified socket stream or resource
Description
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.
Note:
To bind a socket, listen , and accept connections on the socket in s single call use EventHttp::bind() . EventHttp::accept() is needed only if one already has a socket ready to accept connections.
Parameters
-
socket -
Socket resource, stream or numeric file descriptor representing a socket ready to accept connections.
Return Values
Returns TRUE on success. Otherwise FALSE.
Examples
Example #1 EventHttp::accept() example
<?php
$base = new EventBase();
$http = new EventHttp($base);
$addresses = array (
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.
?>
The above example will output something similar to:
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
