Uploading API URL file to AWS S3

Hi,

I am receiving some data through an API, which gives me the URL for an image as well. For downloading the image and storing locally, I use the following code:

$car_photo = $request->data[0]['car_photo']['url'];
$imgname = '1.jpg';
file_put_contents('img/carimages/'.$imgname, file_get_contents($car_photo));

This code picks up the URL from API, pulls its content, and saves it locally to a folder.

Now, instead of storing it locally, I want to upload it to AWS s3 bucket. Previously, I was using following code to upload an incoming file through browser upload and put it on s3 bucket successfully:

$request->file('car_photo')->storePubliclyAs('img/carimgs', $imagename, 's3');

But this code assumes that the REQUEST is carrying the file object; while in the new scenario, $request is only carrying a URL and I am pulling the file locally. Hence I cannot use file methods like 'storePubliclyAs', etc.

How can I send the local file to s3?

Thanks, Saad
