Here's a sample script which downloads a .zip file from a URI using file_get_contents and file_put_contents

<?php

class DownloadZippedFile
{

    public function __construct()
    {
        ;
    }

    public function downloadZippedFile($uri, $fileName)
    {
        $opts = [
            'http' => [
                'method'  => 'GET',
                'header'  => '',
                'follow_location' => 0,
                'request_fulluri' => true,
                'protocol_version' => 1.1,
                'user-agent' => 'Paw/3.1.5 (Macintosh; OS X/10.13.2) GCDHTTPRequest',
                'content' => '',
                'connection' => 'close',
            ],
        ];

        $context = stream_context_create($opts);

        $result = file_get_contents($uri, false, $context);

        // search for a 301, 302 in the $http_response_header array
        if ( stristr($http_response_header[0], 'HTTP/1.1 301') ||
            stristr($http_response_header[0], 'HTTP/1.1 302'))
        {
            // find the location to redirect to
            foreach ($http_response_header as $intIndex => $header) {
                if (strstr($header, 'Location: ')) {
                    // get the location to redirect to by splitting on the space
                    $locationArray = explode(' ', $header);
                    $uri = $locationArray[1];
                }
            }

            # attempt the request again
            file_put_contents($fileName, file_get_contents($uri, false, $context));
        }

        file_put_contents($fileName, file_get_contents($uri, false, $context));
    }
}

function main()
{
    $documentId = '603411390';
    $uri = 'http://mis.ercot.com/misdownload/servlets/mirDownload?doclookupId='.$documentId;
    $fileName = './downloads/'.$documentId.'.zip';

    $downloader = new DownloadZippedFile();
    $downloader->downloadZippedFile($uri, $fileName);
}

main();

The benefit of using PHP's file_get_contents and file_put_contents is these don't rely on any 3rd party libraries (such as cURL), and will work with different versions of PHP

While cURL will work, the PHP methods to use cURL have changed in the past, so you'll have to keep up with the changes from version of version of PHP.

Answer 2

First of all check this sample code and use curl instead of file_get_contents whenever possible.

And second - google doesn't like when someone download their content directly. So you might need to pretend a real browser by adding "normal" headers found in requests of regular browsers.
