添加swf文件时，压缩zip文件

Question

im trying to download swf files from the urls, from number 1752 to number 1760. I made a code and everything seem ok but the files are broken! their size are 0 and they are empty! (the swf files) I dont know what is wrong with my code. here's my code:

<?php 

$num = 1753;
$files = array('');
while($num !== 1760){
array_push($files, '');
$num++;
}
print_r($files);
    $zip = new ZipArchive();

$tmp_file = tempnam('.','');
$zip->open($tmp_file, ZipArchive::CREATE);

foreach($files as $file){

    $download_file = file_get_contents($file);

    $zip->addFromString(basename($file),$download_file);

}

$zip->close();

header('Content-disposition: attachment; filename=Resumes.zip');
header('Content-type: application/zip');
readfile($tmp_file);
?>

help?

The server does not have a file called $num.swf, you're getting a 404 error.

You need to use double quotes if you want PHP to interpolate the variable into its value.

while($num !== 1760){
    $files[] = "mogobe.walla.co.il/Swf/AssetsClean/Items/IconS/$num.swf";
    $num++;
}
