# EventHttp::__construct

(PECL event >= 1.2.6-beta)

EventHttp::__construct — Constructs EventHttp object(the HTTP server)

### Description

public EventHttp::__construct( EventBase `$base` , EventSslContext `$ctx` = `null` )

Constructs the HTTP server object.

### Parameters

`base`

  Associated event base.

`ctx`

  EventSslContext class object. Turns plain HTTP server into HTTPS server. It means that if `ctx` is configured correctly, then the underlying buffer events will be based on OpenSSL sockets. Thus, all traffic will pass through the SSL or TLS.

  > Note:

  > This parameter is available only if `Event` is compiled with OpenSSL support and only with `Libevent 2.1.0-alpha` and higher.

### Return Values

Returns EventHttp object.

### Changelog

Version | Description
--- | ---
PECL event 1.9.0 | OpenSSL support (`ctx`) added.

### Examples

Example #1 Simple HTTP server

    <?php/* * Simple HTTP server. * * To test it: * 1) Run it on a port of your choice, e.g.: * $ php examples/http.php 8010 * 2) In another terminal connect to some address on this port * and make GET or POST request(others are turned off here), e.g.: * $ nc -t 127.0.0.1 8010 * POST /about HTTP/1.0 * Content-Type: text/plain * Content-Length: 4 * Connection: close * (press Enter) * * It will output * a=12 * HTTP/1.0 200 OK * Content-Type: text/html; charset=ISO-8859-1 * Connection: close * * $ nc -t 127.0.0.1 8010 * GET /dump HTTP/1.0 * Content-Type: text/plain * Content-Encoding: UTF-8 * Connection: close * (press Enter) * * It will output: * HTTP/1.0 200 OK * Content-Type: text/html; charset=ISO-8859-1 * Connection: close * (press Enter) * * $ nc -t 127.0.0.1 8010 * GET /unknown HTTP/1.0 * Connection: close * * It will output: * HTTP/1.0 200 OK * Content-Type: text/html; charset=ISO-8859-1 * Connection: close * * 3) See what the server outputs on the previous terminal window. */function _http_dump($req, $data) {    static $counter      = 0;    static $max_requests = 2;    if (++$counter >= $max_requests)  {        echo "Counter reached max requests $max_requests.

The above example will output something similar to:

    a=12
    HTTP/1.0 200 OK
    Content-Type: text/html; charset=ISO-8859-1
    Connection: close

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

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