使用PHPExcel实现Excel文件的导入和导出(模板导出) （转载自用）

function excelToArray(){  
    require_once dirname(__FILE__) . '/Lib/Classes/PHPExcel/IOFactory.php';  
      
    //加载excel文件  
    $filename = dirname(__FILE__).'/result.xlsx';  
    $objPHPExcelReader = PHPExcel_IOFactory::load($filename);    
  
    $sheet = $objPHPExcelReader->getSheet(0);        // 读取第一个工作表(编号从 0 开始)  
    $highestRow = $sheet->getHighestRow();           // 取得总行数  
    $highestColumn = $sheet->getHighestColumn();     // 取得总列数  
  
    $arr = array('A','B','C','D','E','F','G','H','I','J','K','L','M', 'N','O','P','Q','R','S','T','U','V','W','X','Y','Z');  
    // 一次读取一列  
    $res_arr = array();  
    for ($row = 2; $row <= $highestRow; $row++) {  
        $row_arr = array();  
        for ($column = 0; $arr[$column] != 'F'; $column++) {  
            $val = $sheet->getCellByColumnAndRow($column, $row)->getValue();  
            $row_arr[] = $val;  
        }  
          
        $res_arr[] = $row_arr;  
    }  
      
    return $res_arr;  
}

或者 

function excelToArray(){  
    require_once dirname(__FILE__) . '/Lib/Classes/PHPExcel/IOFactory.php';  
      
    //加载excel文件  
    $filename = dirname(__FILE__).'/result.xlsx';  
    $objPHPExcelReader = PHPExcel_IOFactory::load($filename);    
  
    $reader = $objPHPExcelReader->getWorksheetIterator();  
    //循环读取sheet  
    foreach($reader as $sheet) {  
        //读取表内容  
        $content = $sheet->getRowIterator();  
        //逐行处理  
        $res_arr = array();  
        foreach($content as $key => $items) {  
              
             $rows = $items->getRowIndex();              //行  
             $columns = $items->getCellIterator();       //列  
             $row_arr = array();  
             //确定从哪一行开始读取  
             if($rows < 2){  
                 continue;  
             }  
             //逐列读取  
             foreach($columns as $head => $cell) {  
                 //获取cell中数据  
                 $data = $cell->getValue();  
                 $row_arr[] = $data;  
             }  
             $res_arr[] = $row_arr;  
        }  
          
    }  
      
    return $res_arr;  
}

Excel文件导出

/** 
 * 创建(导出)Excel数据表格 
 * @param  array   $list        要导出的数组格式的数据 
 * @param  string  $filename    导出的Excel表格数据表的文件名 
 * @param  array   $indexKey    $list数组中与Excel表格表头$header中每个项目对应的字段的名字(key值) 
 * @param  array   $startRow    第一条数据在Excel表格中起始行 
 * @param  [bool]  $excel2007   是否生成Excel2007(.xlsx)以上兼容的数据表 
 * 比如: $indexKey与$list数组对应关系如下: 
 *     $indexKey = array('id','username','sex','age'); 
 *     $list = array(array('id'=>1,'username'=>'YQJ','sex'=>'男','age'=>24));
