Thinkphp中使用PHPExcel 導入導出excel

ThinkPHP版本：3.2.3
PHPExcel版本：1.8
PHPExcel 官方下載地址：https://github.com/PHPOffice/PHPExcel

下載解壓後目錄結構如下：

1、將目錄中的 Classes 文件夾改名爲 PHPExcel，
2、改名後的文件夾 複製到 Thinkphp/Library/Vender/ 目錄下
完成後目錄結構如下：

3、Application/Admin/Common/function.php 內添加導入導出excel的函數，代碼如下：

注意：ob_end_clean();//清除緩存,避免中文亂碼， 這一行非常重要 ，要放在所有header（）前面

4、使用：查詢mysql數據庫並導出excel

後臺代碼：Application/Admin/Controller/MemberController.Class.php

public function expt(){

        $title  = "Member";
        $th  = array(
            array('id','用戶id'),
            array('truename','姓名'),
            array('phone','手機號')
        );
        $data  = M('Member')->Field('id,truename,phone')->select();
        export_excel($title,$th,$data);
    }

4.2、導入excel

public function impt(){
     if(isset($_FILES["import"]) && ($_FILES["import"]["error"] == 0)){
        $result = import_execl($_FILES["import"]["tmp_name"]);
        if($result["error"] == 1){          
          $execl_data = $result["data"][0]["Content"];
                  foreach($execl_data as $k=>$v){
                      #循環寫入數據庫，或者開啓事務..
                  }
         }
      }
}

前臺代碼: Application/Admin/View/Index/member.html

<a href="{:U('Admin/expt')}">導出Excell</a>
<br />
<form action="" name="impt" id="impt" method="post" enctype="multipart/form-data">
    <h3>導入Excel：</h3><input  type="file" name="import" />
    <input type="submit"  value="導入" onclick="impt();"/>
</form>

<!-- other code -->

<script type="text/javascript">
    function impt(){
        document.getElementById('impt').action="__APP__/Admin/Member/impt";
        document.getElementById('impt').submit();
    }
</script>
