PclZip提取到新的文件夾，如果文件夾已經存在

Question

我使用PclZip解壓壓縮文件，我的問題是我如何通過如果文件夾已經存在創建一個新的文件夾解壓zip文件到不同的文件夾..

感謝您的幫助！

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;
