PHP API file download using Apache

[ssmitj]

I have the credentials to access an API, I am able to access and make some calls that returns data with my PHP site. I have the URL and am sending the correct GET request and headers but I need an example of how to create a file download app.

The way I see it I will create a link that when I click on it in Firefox it will pop-up the box that asks me where I want to save the file. Where can I find an example that shows how to download content (zip archive in this case) from a 3rd party server using their API?

Thank you
Jack

Are you looking for how to force a download dialog?

Or are you trying to save the contents of a remote file?
Curl file_get_contents

Ok, I have the part below:
echo "Get:{$item['Uri']}<br>";
$binaryF = $rsObject->makeCall('get', "/JobData/6530602", "?format=bin");
echo $binaryF;
and it produces:
Get:https://api.xxxxxx.com/JobData/6530602?format=bin
Making a call to:https://api.xxxxxx.com/JobData/6530602?format=bin
and below that some junk text - a lot. This I see as the visual representation of the actual zip file that I am supposed to download? How do I get the server to tell the browser what it is sending?
