Play an audio file from a incoming file without saving

Question

I'm using the ringcentral-php SKD to retrieve call recordings. I'm attempting to get around saving the file before playing it. (Stream or play from temp file) This is the code.

$uri = 'https://media.devtest.ringcentral.com/restapi/v1.0/account/851921005/recording/15694407005/content';

$apiResponse = $platform->get($uri);

$mp3_file = $apiResponse->raw();

file_put_contents("recordings/recording_test.mp3", $mp3_file);//This is not allowed on the server//

echo '<audio controls>
<source src="recordings/recording_test.mp3" type="audio/mpeg">
    </audio>';

The goal is not to save the recordings, just play them on demand. Any ideas?

Concept

You can output content directly to the browser with PHP. Instead of saving the file to disk, you'll send it as a response to the client's browser with headers.

Static

get_audio.php:

$uri = 'https://media.devtest.ringcentral.com/restapi/v1.0/account/851921005/recording/15694407005/content';
$apiResponse = $platform->get($uri);
$mp3_file = $apiResponse->raw();

header('Content-Type: audio/mpeg');

echo $mp3_file;

HTML:

<audio controls>
    <source src="get_audio.php" type="audio/mpeg">
</audio>

Dynamic

And of course you can pass parameters if you need to adjust which audio file to output dynamically:

get_audio.php:

if (!isset($_GET['audioId'])) {
    // Handle the error appropriately in production of course
    die('Audio ID is required');
}

$audioId = $_GET['audioId'];
$uri = 'https://media.devtest.ringcentral.com/restapi/v1.0/account/851921005/recording/' . $audioId . '/content';

$apiResponse = $platform->get($uri);
$mp3_file = $apiResponse->raw();

header('Content-Type: audio/mpeg');

echo $mp3_file;

HTML:

<audio controls>
    <source src="get_audio.php?audioId=15694407005" type="audio/mpeg">
</audio>
