Download file directly from URL to local folder or a folder in remote server

Question

I have download a file from the link & has to save in my local system folder or in a remote server folder. The scenario is that: I have a mailgun domain, when I send a mail to it, Mailgun store function (store()) stores it with all attachments & notifies me. The response from mailgun is catched in catch_email_attachment(), I'm able fetch the response & got the link of attached files. When I run the link directly in browser it gives me the attached file, no problem on that. But I need to download the file inside catch_email_attachment() & to save it in a folder.

The downloadable file is as: "https://API:<API-KEY>@api.mailgun.net/v2/domains/sandboxa6e6ebce3f68475aa3xxxxxxxd60.mailgun.org/messages/eyJwIjogZmFsc2UsICJrIjogImQ0MmZjxxxxxxxxxxxxxxDQwNy1iYzhlLTA2OWMxY2U3MDg2NCIsIxxxxxxxxxxxxxx1Y2UiLCAiYyI6ICJpYWR0cmFpbGVycyJ9/attachments/0"

My codes are below:

public function catch_email_attachment()
{
    $data = $this->input->post(null, true);
    if (!empty($data)) {
        if (isset($data['attachments'])) {
            /*
            Output of $data['attachments'] is below:
            [{"url": "https://api.mailgun.net/v2/domains/sandboxa6e6ebce3f68475aa3xxxxxxxd60.mailgun.org/messages/eyJwIjogZmFsc2UsICJrIjogImQ0MmZjxxxxxxxxxxxxxxDQwNy1iYzhlLTA2OWMxY2U3MDg2NCIsIxxxxxxxxxxxxxx1Y2UiLCAiYyI6ICJpYWR0cmFpbGVycyJ9/attachments/0", "content-type": "image/jpeg", "name": "xxxxxxx.jpeg", "size": 9498}]
            */

            copy('https://API:key-e5ae9afab1fa9xxxxxxxxxxxxxxa95a@api.mailgun.net/v2/domains/sandboxa6e6ebce3f68475axxxxxxxxxxxxxxxxxxxxxxxxxxxx.mailgun.org/messages/eyJwIjogZmFsc2UxxxxxxxxxxxxxxxxxxxxxxxxxxxxmUtNDQwNy1iYzhlLTA2OWMxY2U3MDg2NCIxxxxxxxxxxxxxxxxxxxxxxxxxxxx1Y2UiLCAiYyI6ICJpYWR0cmFpbGVycyJ9/attachments/0', '/var/www/download_loc/');
        }
    }
}

It looks like $data['attachments'] is a json array so you need something like:

    $attachments = json_decode($data['attachments']);
        $api_key = 'APIKEY';
        if ($attachments) {
            foreach ($attachments as $attachment) {

                $context = stream_context_create(array(
                    'http' => array(
                        'header'  => "Authorization: Basic " . base64_encode("API:$api_key")
                    )
                ));

                file_put_contents('/var/www/download_loc/' . $attachment->name, file_get_contents($attachment->url, false, $context));

            }
        }
