如果文件夹已存在，则PclZip提取到新文件夹中

我正在使用PclZip提取zip文件，我的问题是如果文件夹已经退出，我如何通过创建一个新文件夹将zip文件解压缩到不同的文件夹中。

感谢您的帮助！

Answer 1

    $destination_dir = "/foo/bar";
    $new_dir = "/foo/bar2";
    if (is_dir($destination_dir)) {mkdir($new_dir); $destination_dir = $new_dir;}
    $archive = new PclZip($file);
    if ($archive->extract(PCLZIP_OPT_PATH, $destination_dir) == 0) {
        die("Unzip failed. Error : ".$archive->errorInfo(true));
    }
    echo "Successfully extracted files to ".$destination_dir;

Answer 2

    $destination_dir = "/foo/bar";

    if (file_exists($destination_dir)) { $destination_dir = "/foo/bar2";  }

    mkdir($destination_dir);

    $archive = new PclZip($file);
    if ($archive->extract(PCLZIP_OPT_PATH, $destination_dir) == 0) {
        die("Unzip failed. Error : ".$archive->errorInfo(true));
    }
    echo "Successfully extracted files to ".$destination_dir;
