PHP ZIP解压缩

去掉php.ini里面关于zip的注释
解压到当前目录下

        $filepath='d:\\a.zip';
        $zip = new ZipArchive();
        $rs = $zip->open($filepath);
        if($rs){
            $fd=explode(".",basename($filepath));
            $zip->extractTo(dirname($filepath).'/'.$fd[0]);
            $zip->close();
        }
