Pure PHP XML Writer

仅使用基本PHP函数编写的简单XML编写器库。此项目的主要目的是在不使用大量内存的情况下生成大型XML文件（所有元素都传递到写入缓冲区，没有包含所有XML的对象存储在内存中）。

安装

composer require jan-drda/pure-php-xml-writer

然后将example.php复制到您的项目根目录。您可以根据需求修改它并运行。

如果您没有Composer

安装它，非常简单： https://getcomposer.org.cn/doc/00-intro.md

文档

请参阅example.php了解基本用法，我正在编写文档（正在将其复制到那里）。
