download and save a gzip file using php curl - php

Question

I am trying to download a gzip file using curl and php and saving it in a specified location. Below is the code that I am using but everytime it's saving an empty file allthough the gzip file that it's downloading is proper
$file_zip = 'abc.gz'
$fp = fopen("$file_zip", "w");
$request = curl_init();
$headers = array('Content-type: application/x-gzip','Connection: Close');
curl_setopt($request, CURLOPT_URL, $url);
curl_setopt($request, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($request, CURLOPT_TIMEOUT, 0);
curl_setopt($request, CURLOPT_CONNECTTIMEOUT,0);
curl_setopt($request, CURLOPT_HTTPHEADER,$headers);
curl_setopt($request, CURLOPT_FAILONERROR, true);
curl_setopt($request, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($request, CURLOPT_AUTOREFERER, true);
curl_setopt($request, CURLOPT_BINARYTRANSFER,true);
curl_setopt($request, CURLOPT_FILE, $fp);
$zipFile = curl_exec($request);

Answer 1

I found a method that downloads a file to a location with cUrl. Hope it helps:
<?php
function get_file1($file, $local_path, $newfilename)
{
$err_msg = '';
echo "<br>Attempting message download for $file<br>";
$out = fopen($newfilename, 'wb');
if ($out == FALSE){
print "File not opened<br>";
exit;
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_FILE, $out);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_URL, $file);
curl_exec($ch);
echo "<br>Error is : ".curl_error ( $ch);
curl_close($ch);
//fclose($handle);
}//end function
?>
