基于phpexcel的php导出excel类，附注释和调用方法

时间：2022-06-24 17:11:37 编辑：袖梨 来源：一聚教程网

以前我们写过一个PHP通过链式操作将数据输出excel（csv）格式，http://www.111com.net/phper/php-cy/72796.htm，现在我们来学习写一个php基于phpexcel制作的导出excel类

 代码如下 复制代码
/*
*@使用方法。
*引入类库。
*$excel = news excelC();
*$excel->fileName = '文件名称';//设置文件名称，默认为时间戳
*$excel->format = '2007';//文件类型，默认为2007，其他为excel5
*$record = array(
    'delKey'=>array('id','addTime','status'),//如果数据$data中有不需要显示的列，可以在此说明。删除不需要导出的键值
    'sort'          =>array(
                    'keyName'=>array('subjectName','flag'),//按keyName列排序，如果不存在则不排序。
                    //'reorder'=>'DESC',//排序方式，DESC为倒序，ASC为正序。如果keyName存在则排序keyName，如果不存在则按数组的键名排序，如果reorder不存在则不排序
                ),//排序   如果sort存在则排序，否则不排序，如果keyName存在则按设置排序，如果不存在则按字符排序，如果reorder不存在或为空或为DES则正序，等于DESC为倒序。
    'excelStyle'    =>array(
                        'setName'=>'Arial',//字体样式
                        'setSize'=>'12',//字体大小
                    ),//表格全局样式
    'title'         =>array('tableName'=>'学科列表','center'=>true,'direction'=>'right','merge'=>'2','setSize'=>'30'),//标题,center垂直,direction为合并方向。right,left,up,down。 merge为合并几个单元格，setSize为字体大小
    'data'          =>array(
                        array('tableName'=>'科目名称','width'=>'30','setName'=>'宋体','setSize'=>'20','background'=>'red','textColor'=>'white','bold'=>true,'underline'=>true,'borderColor'=>'cyan','center'=>true,),
                        array('tableName'=>'学科','width'=>'50','center'=>true),//颜色表是：black,white,red,green,blue,yellow,magenta,cyan
                    ),//表名称 tableName为名称，width为表格宽度，setName为字体样式，background为背景颜色,textColor为字体颜色，bold为加粗,underline为下划线，borderColor为边框颜色.
    'merge'         =>array(
                        //'flag'=>array('keyword'=>'初','direction'=>'right','merge'=>'2'),merge的键值为需要处理数据数组的键值，keyword为如果存在此关键字才执行其他样式操作，如果keyword不存在则执行所有键值为flag的单元格。
                        'all'=>array('width'=>'30','setName'=>'宋体','setSize'=>'20','background'=>'red','textColor'=>'white','bold'=>true,'underline'=>true,'borderColor'=>'cyan','center'=>true,),
                    ),//
);//导出配置
 
 
*$excel->export($record,$data);//$record为导出配置，$data为数据库的数据,$data可以为数组，也可以为对象。
