Any advice on the best way to safely add PHPSpreadsheet so its available to Joomla! extensions, without messing

yii2框架中整合PHPOffice的PhpSpreadsheet开源库

由 纵饮孤独 提交于 2019-12-06 16:48:20
在所有的php office库( http://www.21doc.net/php/awesomephp#Office )，以前用得最多的版本是PHPOffice/PHPExcel（ https://github.com/PHPOffice/PHPExcel ），不过该库最后更新的版本为2015发布的1.8.1版本，已经终止维护，官方也不建议用户继续使用。 官方不维护PHPExcel后，新起一个项目叫PhpSpreadsheet（ https://github.com/PHPOffice/PhpSpreadsheet ）。新项目使用了大量的php新特性，比如命名空间，PSR标准，性能也比PHPExcel高了不少。 在使用时，由于PhpSpreadsheet是在原PHPExcel基础上开发的，PhpSpreadsheet接口api操作上也和旧的PHPExcel相似，而且支持更多的格式。 整合到yii2框架 下载phpspreadsheet，当前最新版本1.5.0 方式一，composer下载 composer require phpoffice/phpspreadsheet 方式二，对于部分不能用composer顺利下载的用户，可以手工下载源码 PhpSpreadsheet 下载地址： https://github.com/PHPOffice/PhpSpreadsheet
