Summary of super practical PHPExcel [import][export] implementation methods

This article will share with you the implementation method of PHPExcel [Import][Export], which is very practical. Friends who are interested can take a look at the content of this article

First, you need to go to the official website http://www.php.cn/xiazai/leiku/1491. After downloading, you only need the files in the Classes directory.

1. Implementation process of PHPExcel export method

/** 
 * 数据导出 
 * @param array $title   标题行名称 
 * @param array $data   导出数据 
 * @param string $fileName 文件名 
 * @param string $savePath 保存路径 
 * @param $type   是否下载  false--保存   true--下载 
 * @return string   返回文件全路径 
 * @throws PHPExcel_Exception 
 * @throws PHPExcel_Reader_Exception 
 */  
function exportExcel($title=array(), $data=array(), $fileName='', $savePath='./', $isDown=false){  
    include('PHPExcel.php');  
    $obj = new PHPExcel();  
  
    //横向单元格标识  
    $cellName = 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', 'AA', 'AB', 'AC', 'AD', 'AE', 'AF', 'AG', 'AH', 'AI', 'AJ', 'AK', 'AL', 'AM', 'AN', 'AO', 'AP', 'AQ', 'AR', 'AS', 'AT', 'AU', 'AV', 'AW', 'AX', 'AY', 'AZ');  
      
    $obj->getActiveSheet(0)->setTitle('sheet名称');   //设置sheet名称  
    $_row = 1;   //设置纵向单元格标识  
    if($title){  
        $_cnt = count($title);  
        $obj->getActiveSheet(0)->mergeCells('A'.$_row.':'.$cellName[$_cnt-1].$_row);   //合并单元格  
        $obj->setActiveSheetIndex(0)->setCellValue('A'.$_row, '数据导出：'.date('Y-m-d H:i:s'));  //设置合并后的单元格内容  
        $_row++;  
        $i = 0;  
        foreach($title AS $v){   //设置列标题  
            $obj->setActiveSheetIndex(0)->setCellValue($cellName[$i].$_row, $v);  
            $i++;  
        }  
        $_row++;  
    }  
  
    //填写数据  
    if($data){  
        $i = 0;  
        foreach($data AS $_v){  
            $j = 0;  
            foreach($_v AS $_cell){  
                $obj->getActiveSheet(0)->setCellValue($cellName[$j] . ($i+$_row), $_cell);  
                $j++;  
            }  
            $i++;  
        }  
    }  
      
    //文件名处理  
    if(!$fileName){  
        $fileName = uniqid(time(),true);  
    }  
  
    $objWrite = PHPExcel_IOFactory::createWriter($obj, 'Excel2007');  
  
    if($isDown){   //网页下载  
        header('pragma:public');  
        header("Content-Disposition:attachment;filename=$fileName.xls");  
        $objWrite->save('php://output');exit;  
    }  
  
    $_fileName = iconv("utf-8", "gb2312", $fileName);   //转码  
    $_savePath = $savePath.$_fileName.'.xlsx';  
     $objWrite->save($_savePath);  
  
     return $savePath.$fileName.'.xlsx';  
}  
  
//exportExcel(array('姓名','年龄'), array(array('a',21),array('b',23)), '档案', './', true);

2. PHPExcel import method implementation process

/** 
*  数据导入 
* @param string $file excel文件 
* @param string $sheet 
 * @return string   返回解析数据 
 * @throws PHPExcel_Exception 
 * @throws PHPExcel_Reader_Exception 
*/  
function importExecl($file='', $sheet=0){  
    $file = iconv("utf-8", "gb2312", $file);   //转码  
    if(empty($file) OR !file_exists($file)) {  
        die('file not exists!');  
    }  
    include('PHPExcel.php');  //引入PHP EXCEL类  
    $objRead = new PHPExcel_Reader_Excel2007();   //建立reader对象  
    if(!$objRead->canRead($file)){  
        $objRead = new PHPExcel_Reader_Excel5();  
        if(!$objRead->canRead($file)){  
            die('No Excel!');  
        }  
    }  
  
    $cellName = 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', 'AA', 'AB', 'AC', 'AD', 'AE', 'AF', 'AG', 'AH', 'AI', 'AJ', 'AK', 'AL', 'AM', 'AN', 'AO', 'AP', 'AQ', 'AR', 'AS', 'AT', 'AU', 'AV', 'AW', 'AX', 'AY', 'AZ');  
  
    $obj = $objRead->load($file);  //建立excel对象  
    $currSheet = $obj->getSheet($sheet);   //获取指定的sheet表  
    $columnH = $currSheet->getHighestColumn();   //取得最大的列号  
    $columnCnt = array_search($columnH, $cellName);  
    $rowCnt = $currSheet->getHighestRow();   //获取总行数  
  
    $data = array();  
    for($_row=1; $_row<=$rowCnt; $_row++){  //读取内容  
        for($_column=0; $_column<=$columnCnt; $_column++){  
            $cellId = $cellName[$_column].$_row;  
            $cellValue = $currSheet->getCell($cellId)->getValue();  
             //$cellValue = $currSheet->getCell($cellId)->getCalculatedValue();  #获取公式计算的值  
            if($cellValue instanceof PHPExcel_RichText){   //富文本转换字符串  
                $cellValue = $cellValue->__toString();  
            }  
  
            $data[$_row][$cellName[$_column]] = $cellValue;  
        }  
    }  
  
    return $data;  
}
