Last week I tried to create a PHP stream context which set multiple headers; an Authorization header and a Content-Type header. All the examples I could find showed headers built up as a string with newlines added manually, which seemed pretty clunky and not-streams-like to me.
In fact, you've been able to pass this as an array since PHP 5.2.10, so to set multiple headers in the stream context, I just used this:
<?php $options = ["http" => [ "method" => "POST", "header" => ["Authorization: token " . $access_token, "Content-Type: application/json"], "content" => $data ]]; $context = stream_context_create($options);
$access_token had been set elsewhere (in fact I usually put credentials in a separate file and exclude it from source control in an effort not to spread my access credentials further than I mean to!), and
$data is already encoded as JSON. For completeness, you can make the POST request like this:
