Reading simple API returns blank screen?

Question

For some reason I cannot figure out how to fix this online anywhere? I have this simple free Chuck Norris joke API that I'm simply trying to output the JSON of, but it wont work? I just get a blank screen?

In the console the network tab says 200 ok and that the headers are valid? What am I doing wrong?

My code:

<?php

  
  header('Content-Type: application/json');
  header('X-RapidAPI-Host: matchilling-chuck-norris-jokes-v1.p.rapidapi.com');
  header('X-RapidAPI-Key: 341b5c1156msh6827bf7184ef4ddp1c8d09jsnbc52db5d01be');
 


  $str = file_get_contents('https://matchilling-chuck-norris-jokes-v1.p.rapidapi.com/jokes/random');
  
// decode JSON
$json = json_decode($str, true);

// get the data

print_r($json);

Most likely you want to send those headers...

header prints out the headers to you, locally, where you execute it.

With file_get_contents it will be like this:

<?php
$opts = [
    "http" => [
        "method" => "GET",
        "header" => "Content-Type: application/json\r\n" .
            "X-RapidAPI-Host: matchilling-chuck-norris-jokes-v1.p.rapidapi.com\r\n" .
            "X-RapidAPI-Key: 341b5c1156msh6827bf7184ef4ddp1c8d09jsnbc52db5d01be\r\n"
    ]
];

$context = stream_context_create($opts);
$str = file_get_contents('https://matchilling-chuck-norris-jokes-v1.p.rapidapi.com/jokes/random', false, $context);

// decode JSON
$json = json_decode($str, true);

// get the data
print_r($json);

I also kindly suggest switching to curl extension.
