Question

当尝试添加嵌套在另一个添加的空目录中的新空目录时，以下类失败并出现ZipArchive错误23 - “已删除条目”。例如：

dir1:
    file1
    file2
    ...

工作得很好，但有点像：

dir1:
    dir2:
        file1
        ...
    file1
    file1
    ...

尝试添加dir1/dir2时

将失败。

Answer 1

PHP之前zip已通过different means安装。因此，当您更新到5.4时，您可能使用PHP编译或打印了zip扩展，并且在5.1上没有它

Answer 2

经过大量调试和测试不同的选项后，事实证明问题出在addEmptyDir()的调用中。由于某些原因，我仍然没有找到答案，调用无法在Zip中添加目录。但是，我随后发现调用是完全没必要的，因为addFile()在给定相对路径名称（例如'dir1/file1'）时会创建必要的目录。知道了这一点，我刚刚删除了对addEmptyDir()的调用，并且能够正确生成包含相应目录的zip文件。

在PHP 5.1上创建和下载ZipArchive失败，适用于PHP 5.4
