[置顶] phpexcel 的前端封装类

说到phpexcel，做php开发的童鞋可能都不陌生的，强大的excel表格导出类。它到底有多强大呢？可以导出xls，xlsx（唯一见到的可以导出excel2007的php类），html，pdf,csv等。还可以对xml模板进行编辑然后保存，还可以在excel里面设置图片，画表格，字体的大小，字体表格的颜色等，强大得你都想想不到。但phpexcel导出的pdf实在不敢让人恭维。最近研究了下，写了一个类可以同时导出xls，xlsx，csv，html。主要对其进行了前端的封装。现贴代码上来。

}

实现的功能不多，目前只可以简单的同时导出几种格式的文件。

下面为实例代码

$data [0] = array ( '什么' , '20' );
		$data [1] = array ( '小刚' , '20' );
		$data [2] = array ( '小开' , '20' );
	//数据
		$excel = new Waf_excel ();
		$excel->setProperties ( array ( "title" => '不神奇' ) );
		//设置属性 可设置的属性有 creator  lastModifiedBy title  subject  description  keywords  	category。
		$excel->setMenu ( array ( '乱码' , "年纪" ) );//设置菜单栏目
		$excel->setData ( $data );//设在数据
		$excel->setTitle ( "一个神奇的网站" );//设置显示的标题
		$excel->setAttachDir ( "backs" );//设置数据保存的目录 默认情况为 当前目录下的 attach
		$excel->output ("csv", "kk" );//直接下载导出 不生存文件 csv格式 文件名为kk
		
		$excel->save (array("csv"), "kk" )//直接保存到文件夹里，可以同时保存csv html xls xlsx 格式，第一个参数为保存的格式，可为数组也可为字符串,第二参数为文件名。
