would love to know how to exclude folders also

how can we skip initial folder we only need current folder current it is creating all folders from the root directory.

Great script. But when create a zip it will not create the base directory. How to create the base directory in the script?

Use this for windows to exclude root directories

function zipData($source, $destination) { if (extension_loaded('zip')) { if (file_exists($source)) { $zip = new ZipArchive(); if ($zip->open($destination, ZIPARCHIVE::CREATE)) { $source = realpath($source); if (is_dir($source)) { $iterator = new RecursiveDirectoryIterator($source); // skip dot files while iterating $iterator->setFlags(RecursiveDirectoryIterator::SKIP_DOTS); $files = new RecursiveIteratorIterator($iterator, RecursiveIteratorIterator::SELF_FIRST); foreach ($files as $file) { $file = realpath($file); if (is_dir($file)) { $zip->addEmptyDir(str_replace("{$source}\\", '', $file)); } else if (is_file($file)) { $zip->addFromString(str_replace("{$source}\\", '', $file), file_get_contents($file)); } } } else if (is_file($source)) { $zip->addFromString(basename($source), file_get_contents($source)); } } return $zip->close(); } } return false;
