Multiple file package Download instance:

$filsarr = Array (".. /folder1 ",". /folder2 ",". /folder5 ",". /folder11 "); You can select the contents of each directory $filename = '. /download/zipfilename.zip ';  The path of the compressed file Create_zip ($filsarr, $filename); Header ("Cache-control:public");  Header ("Content-description:file Transfer"); Header (' content-disposition:attachment; Filename= '. basename ($filename)); FileName header ("Content-type:application/zip");    Header in zip format ("content-transfer-encoding:binary");    Tell the browser that this is the header of the binary file (' content-length: '.
