(this drives me nuts, I love upgrading systems but the downside is you have to work with the old ones first and none of the tools you want have been invented yet!)
For OAuth2, all I had to be able to do was to send an
Authorization header with my web request from PHP. My second-favourite way of making API calls from PHP is to use PHP’s stream handling, so I did that. It’s not code you see very often but it’s super-simple and it works on every PHP platform I’ve tried so far, so here’s an example:
// assemble the options $opts = array( 'http'=>array( 'header'=> "Authorization: Bearer " . $access_token ) ); // create the context $context = stream_context_create($opts); // now make the request! Use the context and simply output the result echo file_get_contents('http://api.example.com/endpoint1', false, $context);
If you’re trying to make an API call from PHP and installing better tools is hard for any reason, this example may help!
