//If the zip file already exists and is set to not overwrite, return false
if(file_exists($destination) && !$overwrite) { return false; }
$valid_files = array();
//Get the real and valid file name
if(is_array($files)) {
foreach($ files as $file) {
if(file_exists($file)) {
$valid_files[] = $file;
}
}
}
//If there are real and valid files
if(count($valid_files)) {
$zip = new ZipArchive();
//Open the file. If the file already exists, overwrite it, if not, create it.
if($zip->open($destination,$overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE ) !== true) { return false; }
//Add files to the compressed file
foreach($valid_files as $file) {
$zip->addFile($file,$file);
}
// Close the file
$zip->close();
//Check whether the file exists
return file_exists($destination);
