hy all, I want to make code for download multiple file in php so I make in zip file. my code work and can create sip file but when I want to open the zip file appear error message like this " the archive is either is unknown format or damaged ". I already attach the error message

this is my full code

function zipFilesAndDownload($file_names,$archive_file_name,$file_path)
{
	$zip = new ZipArchive();
	//create the file and throw the error if unsuccessful
	if ($zip->open($archive_file_name, ZipArchive::CREATE )!==TRUE) {
    	exit("cannot open <$archive_file_name>\n");
	}
	else {
	$zip->open($archive_file_name, ZipArchive::CREATE );
	//add each files of $file_name array to archive
	foreach($file_names as $files)
	{
  		$zip->addFile($file_path.$files,$files);
		//echo $file_path.$files,$files."<br />";
	}
	$zip->close();
	//then send the headers to foce download the zip file
	header("Content-type: application/zip"); 
	header("Content-Disposition: attachment; filename=$archive_file_name"); 
	header("Pragma: no-cache"); 
	header("Expires: 0"); 
	readfile("$archive_file_name");
	exit;
	}
}

then here I call the function

$file_names = array('makeZipinPHP.jpg','Speed_Kills.wav','tick.jpg','webinfopedia.com.txt');
	$archive_file_name=$name."$ico.zip";
	$file_path=$_SERVER['DOCUMENT_ROOT'].'/download/';
	zipFilesAndDownload($file_names,$archive_file_name,$file_path);

can some one give example about this problem? I get stack with my project because of this

thank you in advance

The Content-Length header is missing for one. Search this forum, there are some threads about this.

I already try to put Content-Length header, the problem still same only the size of zip file going bigger. this is my header now

header('Content-Description: File Transfer');
		header('Content-Type: application/octet-stream');
		header('Content-Disposition: attachment; filename='.basename($archive_file_name));
		header('Content-Transfer-Encoding: binary');
		header('Expires: 0');
		header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
		header('Pragma: public');
		header('Content-Length: ' . filesize($archive_file_name));
		ob_clean();
		flush();
		readfile($archive_file_name);

I think the problem is not in the header but when creating zip file. but I am not sure about that. Can u give me some advice?

I don't know why you open your zip file twice, and why you pass $files as the second parameter to addFile. I suggest you add some error checking to the creation of your zip file.

Finally I already solve this problem I change the zip function and add 1 class

this is my file now
hope can help.

in here I also put counter to how much times the file already downloaded
