php中excel文件數據的導入和導出

1、先下載 https://github.com/PHPOffice/PHPExcel
2、將SDK解壓之後的Class文件拷貝到自己的項目。

一、數據導入

/**

 *  數據導入

 * @param string $file excel文件

 * @param string $sheet

 * @return string   返回解析數據

 * @throws PHPExcel_Exception

 * @throws PHPExcel_Reader_Exception

 */

function importExecl($file='', $sheet=0){

    $file = iconv("utf-8", "gb2312", $file);   //轉碼

    if(empty($file) OR !file_exists($file)) {

        die('file not exists!');

    }

    include(dirname(__FILE__) . '/includes/Classes/PHPExcel.php');  //引入PHP EXCEL類

    $objRead = new PHPExcel_Reader_Excel2007();   //建立reader對象

    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對象

    $currSheet = $obj->getSheet($sheet);   //獲取指定的sheet表

    $columnH = $currSheet->getHighestColumn();   //取得最大的列號

    $columnCnt = array_search($columnH, $cellName);

    $rowCnt = $currSheet->getHighestRow();   //獲取總行數



    $data = array();

    for($_row=1; $_row<=$rowCnt; $_row++){  //讀取內容

        for($_column=0; $_column<=$columnCnt; $_column++){

            $cellId = $cellName[$_column].$_row;

            $cellValue = $currSheet->getCell($cellId)->getValue();

            //$cellValue = $currSheet->getCell($cellId)->getCalculatedValue();  #獲取公式計算的值

            if($cellValue instanceof PHPExcel_RichText){   //富文本轉換字符串

                $cellValue = $cellValue->__toString();

            }



            $data[$_row][$cellName[$_column]] = $cellValue;

        }

    }

    array_shift($data);
    return $data;
}

↑↑↑↑↑↑這是我用的方法
以下是另外兩種方法
1、

1.  function excelToArray(){  
2.  require_once dirname(__FILE__) . '/Lib/Classes/PHPExcel/IOFactory.php';  

4.  //加載excel文件  
5.  $filename = dirname(__FILE__).'/result.xlsx';  
6.  $objPHPExcelReader = PHPExcel_IOFactory::load($filename);    

8.  $sheet = $objPHPExcelReader->getSheet(0);        // 讀取第一個工作表(編號從 0 開始)  
9.  $highestRow = $sheet->getHighestRow();           // 取得總行數  
10.  $highestColumn = $sheet->getHighestColumn();     // 取得總列數  

12.  $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');  
13.  // 一次讀取一列  
14.  $res_arr = array();  
15.  for ($row = 2; $row <= $highestRow; $row++) {  
16.  $row_arr = array();  
17.  for ($column = 0; $arr[$column] != 'F'; $column++) {  
18.  $val = $sheet->getCellByColumnAndRow($column, $row)->getValue();  
19.  $row_arr[] = $val;  
20.  }  

22.  $res_arr[] = $row_arr;  
23.  }  

25.  return $res_arr;  
26.  }  

2、

1.  function excelToArray(){  
2.  require_once dirname(__FILE__) . '/Lib/Classes/PHPExcel/IOFactory.php';  

4.  //加載excel文件  
5.  $filename = dirname(__FILE__).'/result.xlsx';  
6.  $objPHPExcelReader = PHPExcel_IOFactory::load($filename);    

8.  $reader = $objPHPExcelReader->getWorksheetIterator();  
9.  //循環讀取sheet  
10.  foreach($reader as $sheet) {  
11.  //讀取表內容  
12.  $content = $sheet->getRowIterator();  
13.  //逐行處理  
14.  $res_arr = array();  
15.  foreach($content as $key => $items) {  

17.  $rows = $items->getRowIndex();              //行  
18.  $columns = $items->getCellIterator();       //列  
19.  $row_arr = array();  
20.  //確定從哪一行開始讀取  
21.  if($rows < 2){  
22.  continue;  
23.  }  
24.  //逐列讀取  
25.  foreach($columns as $head => $cell) {  
26.  //獲取cell中數據  
27.  $data = $cell->getValue();  
28.  $row_arr[] = $data;  
29.  }  
30.  $res_arr[] = $row_arr;  
31.  }  

33.  }  

35.  return $res_arr;  
36.  }  

二、Excel文件導出

1.  /** 
2.  * 創建(導出)Excel數據表格 
3.  * @param  array   $list        要導出的數組格式的數據 
4.  * @param  string  $filename    導出的Excel表格數據表的文件名 
5.  * @param  array   $indexKey    $list數組中與Excel表格表頭$header中每個項目對應的字段的名字(key值) 
6.  * @param  array   $startRow    第一條數據在Excel表格中起始行 
7.  * @param  [bool]  $excel2007   是否生成Excel2007(.xlsx)以上兼容的數據表 
8.  * 比如: $indexKey與$list數組對應關係如下: 
9.  *     $indexKey = array('id','username','sex','age'); 
10.  *     $list = array(array('id'=>1,'username'=>'YQJ','sex'=>'男','age'=>24)); 
11.  */  
12.  function exportExcel($list,$filename,$indexKey,$startRow=1,$excel2007=false){  
13.  //文件引入  
14.  require_once APP_ROOT.'/Api/excel/PHPExcel.php';  
15.  require_once APP_ROOT.'/Api/excel/PHPExcel/Writer/Excel2007.php';  

17.  if(empty($filename)) $filename = time();  
18.  if( !is_array($indexKey)) return false;  

20.  $header_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');  
21.  //初始化PHPExcel()  
22.  $objPHPExcel = new PHPExcel();  

24.  //設置保存版本格式  
25.  if($excel2007){  
26.  $objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);  
27.  $filename = $filename.'.xlsx';  
28.  }else{  
29.  $objWriter = new PHPExcel_Writer_Excel5($objPHPExcel);  
30.  $filename = $filename.'.xls';  
31.  }  

33.  //接下來就是寫數據到表格裏面去  
34.  $objActSheet = $objPHPExcel->getActiveSheet();  
35.  //$startRow = 1;  
36.  foreach ($list as $row) {  
37.  foreach ($indexKey as $key => $value){  
38.  //這裏是設置單元格的內容  
39.  $objActSheet->setCellValue($header_arr[$key].$startRow,$row[$value]);  
40.  }  
41.  $startRow++;  
42.  }  

44.  // 下載這個表格，在瀏覽器輸出  
45.  header("Pragma: public");  
46.  header("Expires: 0");  
47.  header("Cache-Control:must-revalidate, post-check=0, pre-check=0");  
48.  header("Content-Type:application/force-download");  
49.  header("Content-Type:application/vnd.ms-execl");  
50.  header("Content-Type:application/octet-stream");  
51.  header("Content-Type:application/download");;  
52.  header('Content-Disposition:attachment;filename='.$filename.'');  
53.  header("Content-Transfer-Encoding:binary");  
54.  $objWriter->save('php://output');  
55.  }  

導出文件，還可以設置模板

1.  function exportExcel($list,$filename,$indexKey=array()){  
2.  require_once dirname(__FILE__) . '/Lib/Classes/PHPExcel/IOFactory.php';  
3.  require_once dirname(__FILE__) . '/Lib/Classes/PHPExcel.php';  
4.  require_once dirname(__FILE__) . '/Lib/Classes/PHPExcel/Writer/Excel2007.php';  

6.  $header_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');  

8.  //$objPHPExcel = new PHPExcel();                        //初始化PHPExcel(),不使用模板  
9.  $template = dirname(__FILE__).'/template.xls';          //使用模板  
10.  $objPHPExcel = PHPExcel_IOFactory::load($template);     //加載excel文件,設置模板  

12.  $objWriter = new PHPExcel_Writer_Excel5($objPHPExcel);  //設置保存版本格式  

14.  //接下來就是寫數據到表格裏面去  
15.  $objActSheet = $objPHPExcel->getActiveSheet();  
16.  $objActSheet->setCellValue('A2',  "活動名稱：江南極客");  
17.  $objActSheet->setCellValue('C2',  "導出時間：".date('Y-m-d H:i:s'));  
18.  $i = 4;  
19.  foreach ($list as $row) {  
20.  foreach ($indexKey as $key => $value){  
21.  //這裏是設置單元格的內容  
22.  $objActSheet->setCellValue($header_arr[$key].$i,$row[$value]);  
23.  }  
24.  $i++;  
25.  }  

27.  // 1.保存至本地Excel表格  
28.  //$objWriter->save($filename.'.xls');  

30.  // 2.接下來當然是下載這個表格了，在瀏覽器輸出就好了  
31.  header("Pragma: public");  
32.  header("Expires: 0");  
33.  header("Cache-Control:must-revalidate, post-check=0, pre-check=0");  
34.  header("Content-Type:application/force-download");  
35.  header("Content-Type:application/vnd.ms-execl");  
36.  header("Content-Type:application/octet-stream");  
37.  header("Content-Type:application/download");;  
38.  header('Content-Disposition:attachment;filename="'.$filename.'.xls"');  
39.  header("Content-Transfer-Encoding:binary");  
40.  $objWriter->save('php://output');  
41.  }  

先弄一個excel模板

然後使用該模板導出數據
