PHP5 - Retrieve file from another site and zip it

HI GUys,

Noob here.. some help is very much appreciated. There are a few csv files hosted on another website n i'm trying to retrieve them and package into a zip file to download. Zipping seems to work but the package is always empty. Any help is very much appreciated... This is in PHP by the way.
<?php

$zip = new ZipArchive();
$filename = "test114.zip";
$numParts = count($file_names);
if ($zip->open($filename, ZIPARCHIVE::CREATE)!==TRUE)
{
exit("cannot open <$filename>\n");
}



$file=/* some URL address hosting this csv file*/".csv";
$filedata = fopen ($file, "r");
$contents = fread($filedata, filesize($file));
$zip->addFile($filedata, "file1");
fclose($filedata);


$zip->close();
header('Content-Type: application/zip');
header("Content-Disposition: attachment; filename=\"".$filename."\".zip;");
header('Content-Length: ' . filesize($filename));
readfile($filename);

?>

Take a closer look at which variables you're using.

After you've realized the problem, do away with fopen() and such and use file_get_contents instead.

Dear Friend

I think i can help you
In case if the external site doesn’t give the read permission then it will return blank zip.
Use this Download Headers



Thanks
