解决方案

  1. Validate the ZIP file using 'unzip -t' on the command line before processing, and request a fresh upload from the user if it fails.
  2. Use ZipArchive::open() with ZIPARCHIVE::CHECKCONS flag to detect corruption early and provide a user-friendly error message.

无效尝试

常见但无效的做法:

  1. 95% 失败

    Increasing PHP's memory_limit does not fix CRC errors, as the issue is with file integrity, not memory.

  2. 90% 失败

    Re-uploading the same corrupted file will produce the same CRC error.

  3. 80% 失败

    Setting ZipArchive::CHECKCONS to false may bypass the check but could lead to incomplete or corrupted extracted data.
