Hello again Stackoverflow! I want to backup a folder with all its content including (empty) subfolders and every file in them, whilst excluding a single folder (and ofcourse . and ..). The folder that needs to be excluded is aaa.

So when I run this script (every folder does have chmod 0777) it runs without errors, but the ZIP file doesn't show up. Why? And how can I solve this?

Thanks in advance!

function addFolderToZip($dir, $zipArchive, $zipdir = ''){ 
        if (is_dir($dir)) { 
            if ($dh = opendir($dir)) { 

                //Add the directory 
                if(!empty($zipdir)) $zipArchive->addEmptyDir($zipdir); 

                // Loop through all the files 
                while (($file = readdir($dh)) !== false) { 

                    //If it's a folder, run the function again! 
                    if(!is_file($dir . $file)){ 
                        // Skip parent and root directories, and any other directories you want
                        if( ($file !== ".") && ($file !== "..") && ($file !== "aa")){ 
                            addFolderToZip($dir . $file . "/", $zipArchive, $zipdir . $file . "/"); 
                        } 

                    }else{ 
                        // Add the files 
                        $zipArchive->addFile($dir . $file, $zipdir . $file); 

                    } 
                } 
            } 
        } 
    }

After a while of fooling around this is what I found working. Use it as seen below.

$zipArchive = new ZipArchive;   

$name = 'backups\backup_'. time() .'.zip';

$zipArchive->open($name, ZIPARCHIVE::CREATE | ZIPARCHIVE::OVERWRITE);

addFolderToZip($path, $zipArchive);
