PHPExcel(see GitHub repository) is probably your best option. It's very slick and easy to use, I've had no problem with the new XLSX format.

PHPExcel（请参阅GitHub 存储库）可能是您的最佳选择。它非常流畅且易于使用，我对新的 XLSX 格式没有任何问题。

XLSXReader(available on GitHub) is based on SimpleXLSX(see answer by Sergey Shuchkin).

XLSXReader（可在GitHub 上获得）基于SimpleXLSX（请参阅 Sergey Shuchkin 的回答）。

Convert dates from xlsx using XLSXReader::toUnixTimeStamp.

使用 .xlsx 转换日期XLSXReader::toUnixTimeStamp。

    SimpleXLSX php class v0.4 (Artistic License)
    Created by Sergey Schuchkin from http://www.sibvision.ru - professional php developers team 2010-2011
    Downloadable from GitHub.

Key Changes include:
    Separation into two classes - one for the Workbook and one for Worksheets
    Access to sheets by name or sheet id
    Use of ZIP extension
    On-demand access of files inside zip
    On-demand access to sheet data
    No storage of XML objects or XML text
    When parsing rows, include empty rows and null cells so that data array has same number of elements for each row
    Configuration option for removing trailing empty rows
    Better handling of cells with style information but no value
    Change of class names and method names
    Removed rowsEx functionality including extraction of hyperlinks
