PHP can't get json from local page, only remote url

I'm currently building a site using the Slim framework. I have an endpoint setup on my site and it is working but when trying to get it using PHP file_get_contents() and json_decode() nothing is returned. When I run the same code but change out the url to a remote public API, the json is decoded and output to the page.

Working Code

$url = "https://jsonplaceholder.typicode.com/users";
$contents = file_get_contents($url); 
$results = json_decode($contents); // Returns JSON array

Does not work with local site

$url = "https://local/api/endpoint";
$contents = file_get_contents($url); 
$results = json_decode($contents); // Returns NULL

Any ideas on what could be causing this? Possibly headers?

Your local endpoint is failing because php is unable to verify the SSL certificate, in the case you are using a self signed certificate. In local development you can circumvent SSL CA checking by modifying the default stream context:

$stream_opts = [
    "ssl" => [
        "verify_peer"=>false,
        "verify_peer_name"=>false,
    ]
];  
$response = file_get_contents("https://local/api/endpoint",
           false, stream_context_create($stream_opts));
