Generate Zip Compressed files from PHP, support file and archive path lookup

/** new Creatzip ($_dir,$_zipname); *@ _dir is a compressed folder name, you can use the path, example ' a ' or ' a/test.txt ' or ' test.txt ' *@ _zipname is the compressed package name,    can use the path, example ' A/test.zip ' or ' test.zip ' **/class creatzip {private $_dir;    Private $_zipdir;         Private $_zipname;        Public function __construct ($dir, $zipName) {$this->_dir = $dir;        $this->_zipdir = basename ($dir);        $this->_zipname = $zipName;        $this->mkdirs ();    $this->creat (); }//Detect and generate the directory private Function mkdirs () {if (!is_dir (dirname ($this->_zipname))) {$arr = explode            ('/', dirname ($this->_zipname));            $arrs = "; foreach ($arr as $value) {if (!is_dir ($arrs. $value)) {if (!! mkdir ($arrs. $value)) {$arrs. = $value.
