PHP导出Excel通过XML PHPExcelXML
最近在项目需要把数据导出表格,之前也做过类似的工作但没有去总结。在之前使用大名鼎鼎的Phpexcel(phpexcel.codeplex.com)导出表格，很强大功能很多，它也有很多优点，但也发现一些问题比如
功能太多太复杂，在导出中有很多用不到的功能
必须使用php zip扩展，本地没什么问题很多线上不支持zip扩展
还有一个比较大的问题就是占用内存太多，其中需要导出1万行数据活着更多就不给力了。
尤其在第三个问题上不得不放弃使用PHPEXCEL选择使用xml导出(其实PHPEXCEL也是基于Microsoft's OpenXML 导出的具体细节没研究)，同样也有一些问题 比如打开会有弹出框提示如下：
对于这个问题的解决目前还没有其他办法解决 但可以通过另存为的办法解决。
通过XML导出最开始的想法来自于Yii的一个扩展http://www.yiiframework.com/extension/phpexcel，使用的时候发现功能太简单表格合并设置宽高等最基本的功能都不支持，并且编写格式复杂不够友好，于是打算再次基础上重新开发一个基于XML并且编写风格和PHPEXCEL尽量保持一致的导出方法 代称为PHPExcelXML。
目前可以支持一下功能
1.设置行列宽高,
2.行列合并
3.设置基本样式字体大小
4.支持多sheet展示
5.具有友好的编码风格
6.支持1w行的数据导出 目前测试是30M以上(再多木有去测试)。
目前发表在Yii论坛 当然不仅仅支持Yii 他是独立的 (http://www.yiiframework.com/forum/index.php?/topic/22365-extension-phpexcelxml)。代码转成图片贴出来的，以后将继续增加功能主要包括设置字体样式居中等功能以及尽量解决之前的弹出框问题。
鄙视一把新浪blog贴代码不好使，具体换个blog或者自己搭一个。下面是PHPExcelXML的测试代码
具体代码贴一下 很可能注释都没了 可以直接去Yii上面去看代码也可以联系我 下面是贴图 点击可以放大~
