这篇文章主要介绍了php实现的操作excel类,较为详细的分析说明了PHP操作excel的具体技巧,包括PHP针对excel的创建、打开、读取、修改等,需要的朋友可以参考下。
本文实例讲述了php实现的操作excel类,分享给大家供大家参考,具体如下:
- <?php
- class Excel
- {
- static $instance=null;
- private $excel=null;
- private $workbook=null;
- private $workbookadd=null;
- private $worksheet=null;
- private $worksheetadd=null;
- private $sheetnum=1;
- private $cells=array();
- private $fields=array();
- private $maxrows;
- private $maxcols;
- private $filename;
- //构造函数
- private function Excel()
- {
- $this->excel = new COM("Excel.Application") or die("Did Not Connect");
- }
- //类入口
- public static function getInstance()
- {
- if(null == self::$instance)
- {
- self::$instance = new Excel();
- }
- return self::$instance;
- }
- //设置文件地址
- public function setFile($filename)
- {
- return $this->filename=$filename;
- }
- //打开文件
- public function Open()
- {
- $this->workbook=$this->excel->WorkBooks->Open($this->filename);
- }
- //设置Sheet
- public function setSheet($num=1)

- }
- }
- //取得表所有值并写进数组
- private function getCells()
