CURL,JSON and PHP - php

Question

I am working to connect with an API using curl and PHP
I have this CURL statement
curl -i --user api:YXBpOmFiY2RlZmdoaWprbG1ub3BxcnN0dXZ3eHl6MDEyMzQ1 --data-binary #test.png https://api.blahblah.com/blah
where YXBpOmFiY2RlZmdoaWprbG1ub3BxcnN0dXZ3eHl6MDEyMzQ1 is the api key and #test.png is the image file I need to transfer to the API for upload. What I don't get is how to write the curl for the link above
and I also have this Example Statement as given by the site for developers(looks a JSON)
POST /blah HTTP/1.1
Host: api.blahblah.com
Authorization: Basic YXBpOmFiY2RlZmdoaWprbG1ub3BxcnN0dXZ3eHl6MDEyMzQ1
Till now, I have written this up,
$url = 'https://api.tinypng.com/shrink';
$image = 'bf4lwp2.png';
$key = 'YXBpOmFiY2RlZmdoaWprbG1ub3BxcnN0dXZ3eHl6MDEyMzQ1';
$jsonscript = array(
'Host' => 'api.tinypng.com',
'Authorization' => $key );
$json_string = json_encode($jsonscript);
$ch = curl_init($url);
// Disable SSL verification
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'api:'.$key);
curl_setopt($ch, CURLOPT_PUT, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FILE, $image);
// Execute
$result=curl_exec($ch);
Also, if my request is a success, I get this...
HTTP/1.1 201 Created
Location: https://api.blahblah.com/blahblah.png
Content-Type: application/json; charset=utf-8
{
"input": {
"size": 87654
},
"output": {
"size": 102020,
"ratio": 0.236
}
}
I know I have to use file_get_contents() to get all that, but I don't know what URL to put in that function.

To get data from json first you can use json decode and than use foreach loop to
parse those data into variables
