I found a similar question at Sending HTTP/2 POST request in Ruby But I want to update my server with PHP
The new Apple push notification HTTP/2 based API described here: https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/APNsProviderAPI.html
Anyone with HTTP/2 experience help me with making a request as a client in PHP.
The CURL extension for PHP >= 5.5.24 has support for HTTP/2. (since this commit)
You also need a libcurl installed — the underlying library that the curl functions use — with HTTP/2 support enabled. That means a libcurl newer than 7.38.0 but really, the newer the better. Libcurl has to have been built with HTTP/2 support explicitly enabled, using the --with-nghttp2
flag at compile time.
Just use curl as you'd normally use it, and set the CURLOPT_HTTP_VERSION
option to use HTTP/2 by passing in CURL_HTTP_VERSION_2_0
. Then you'll get the request upgraded to version 2 if the client and server both support it.
Prior to PHP 5.5.24, if libcurl has been built with HTTP/2 support, you can pass in the int value of CURL_HTTP_VERSION_2_0
explicitly as PHP will still pass it through to libcurl. Currently, it has a value of 3
— this should not change, but could.
if (!defined('CURL_HTTP_VERSION_2_0')) {
define('CURL_HTTP_VERSION_2_0', 3);
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_2_0);
