如何將數據導出到使用PHPExcel

Question

我採取從limesurvey源代碼，並添加了PHPExcel庫我limesurvey代碼將數據導出到Excel文件，你點擊一個鏈接後，Excel文件。目前，excel文件打開時會顯示一些虛擬數據，沒有問題。在用戶輸入調查信息後，我需要能夠從Web服務器動態添加數據。我查看了一些我已經找到的網站，但我沒有多少運氣。誰能幫我嗎？

Answer 1

如果您複製此直接，那麼：

->setCellValue('B2', Ackermann') 

應該

->setCellValue('B2', 'Ackermann') 

在回答你的問題：

獲取您從limesurvey想要的數據，並使用setCellValue（）這些數據值存儲在要存儲它的細胞。

的在/測試Quadratic.php例如文件可能有助於作爲起點：它從輸入形式取數據並將其設置爲細胞在Excel工作簿。

一個非常簡單的例子：

// Create your database query 
$query = "SELECT * FROM myDataTable"; 

// Execute the database query 
$result = mysql_query($query) or die(mysql_error()); 

// Instantiate a new PHPExcel object 
$objPHPExcel = new PHPExcel(); 
// Set the active Excel worksheet to sheet 0 
$objPHPExcel->setActiveSheetIndex(0); 
// Initialise the Excel row number 
$rowCount = 1; 
// Iterate through each result from the SQL query in turn 
// We fetch each database result row into $row in turn 
while($row = mysql_fetch_array($result)){ 
    // Set cell An to the "name" column from the database (assuming you have a column called name) 
    // where n is the Excel row number (ie cell A1 in the first row) 
    $objPHPExcel->getActiveSheet()->SetCellValue('A'.$rowCount, $row['name']); 
    // Set cell Bn to the "age" column from the database (assuming you have a column called age) 
    // where n is the Excel row number (ie cell A1 in the first row) 
    $objPHPExcel->getActiveSheet()->SetCellValue('B'.$rowCount, $row['age']); 
    // Increment the Excel row counter 
    $rowCount++; 
} 

// Instantiate a Writer to create an OfficeOpenXML Excel .xlsx file 
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel); 
// Write the Excel file to filename some_excel_file.xlsx in the current directory 
$objWriter->save('some_excel_file.xlsx');

使用現有的代碼爲基礎

// Instantiate a new PHPExcel object 
$objPHPExcel = new PHPExcel(); 
// Set the active Excel worksheet to sheet 0 
$objPHPExcel->setActiveSheetIndex(0); 
// Initialise the Excel row number 
$rowCount = 1; 

//start of printing column names as names of MySQL fields 
$column = 'A'; 
for ($i = 1; $i < mysql_num_fields($result); $i++) 
{ 
    $objPHPExcel->getActiveSheet()->setCellValue($column.$rowCount, mysql_field_name($result,$i)); 
    $column++; 
} 
//end of adding column names 

//start while loop to get data 
$rowCount = 2; 
while($row = mysql_fetch_row($result)) 
{ 
    $column = 'A'; 
    for($j=1; $j<mysql_num_fields($result);$j++) 
    { 
     if(!isset($row[$j])) 
      $value = NULL; 
     elseif ($row[$j] != "") 
      $value = strip_tags($row[$j]); 
     else 
      $value = ""; 

     $objPHPExcel->getActiveSheet()->setCellValue($column.$rowCount, $value); 
     $column++; 
    } 
    $rowCount++; 
} 


// Redirect output to a client’s web browser (Excel5)

header('Content-Disposition: attachment;filename="Limesurvey_Results.xls"');

我目前使用此功能在我的項目經過一系列谷歌上搜索到下載下面的完整的示例從SQL語句

// $sql = sql query e.g "select * from mytablename" 
    // $filename = name of the file to download 
     function queryToExcel($sql, $fileName = 'name.xlsx') { 
       // initialise excel column name 
       // currently limited to queries with less than 27 columns 
     $columnArray = 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"); 
       // Execute the database query 
       $result = mysql_query($sql) or die(mysql_error()); 

       // Instantiate a new PHPExcel object 
       $objPHPExcel = new PHPExcel(); 
       // Set the active Excel worksheet to sheet 0 
       $objPHPExcel->setActiveSheetIndex(0); 
       // Initialise the Excel row number 
       $rowCount = 1; 
    // fetch result set column information 
       $finfo = mysqli_fetch_fields($result); 
// initialise columnlenght counter     
$columnlenght = 0; 
       foreach ($finfo as $val) { 
// set column header values     
    $objPHPExcel->getActiveSheet()->SetCellValue($columnArray[$columnlenght++] . $rowCount, $val->name); 
       } 
// make the column headers bold 
       $objPHPExcel->getActiveSheet()->getStyle($columnArray[0]."1:".$columnArray[$columnlenght]."1")->getFont()->setBold(true); 

       $rowCount++; 
       // Iterate through each result from the SQL query in turn 
       // We fetch each database result row into $row in turn 

       while ($row = mysqli_fetch_array($result, MYSQL_NUM)) { 
        for ($i = 0; $i < $columnLenght; $i++) { 
         $objPHPExcel->getActiveSheet()->SetCellValue($columnArray[$i] . $rowCount, $row[$i]); 
        } 
        $rowCount++;

$this->load->library('excel'); 
$file_name = 'Demo'; 
$arrHeader = array('Name', 'Mobile'); 
$arrRows = array(0=>array('Name'=>'Jayant','Mobile'=>54545), 1=>array('Name'=>'Jayant1', 'Mobile'=>44454), 2=>array('Name'=>'Jayant2','Mobile'=>111222), 3=>array('Name'=>'Jayant3', 'Mobile'=>99999)); 
$this->excel->getActiveSheet()->fromArray($arrHeader,'','A1'); 
$this->excel->getActiveSheet()->fromArray($arrRows); 
header('Content-Type: application/vnd.ms-excel'); //mime type 
header('Content-Disposition: attachment;filename="'.$file_name.'"'); //tell browser what's the file name 
header('Cache-Control: max-age=0'); //no cache 
$objWriter = PHPExcel_IOFactory::createWriter($this->excel, 'Excel5'); 
$objWriter->save('php://output');
