Can PHP handle redirects when downloading files from a remote server?
When downloading files from a remote server using PHP, it is important to handle redirects that may occur during the download process. This can be achieved by setting the `follow_location` option to `true` in a stream context when using `file_get_contents()` or by using the cURL extension with the `CURLOPT_FOLLOWLOCATION` option enabled.
// Using file_get_contents with stream context
$remoteFile = 'http://example.com/file.zip';
$context = stream_context_create(['http' => ['follow_location' => true]]);
$fileContents = file_get_contents($remoteFile, false, $context);
file_put_contents('localfile.zip', $fileContents);
// Using cURL
$remoteFile = 'http://example.com/file.zip';
$ch = curl_init($remoteFile);
$fp = fopen('localfile.zip', 'w');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_exec($ch);
curl_close($ch);
fclose($fp);
