使用 PHP 将 txt 文件上传到数据库，然后 return Excel 文件

Question

我需要做的是使用 PHP 将 txt 文件上传到数据库中，根据 table 进行一些计算，然后 return 得到 Excel 文件.

此代码运行良好，但我没有从 .txt 文件中获取所有数据，因为它似乎在找到逗号时停止。

代码如下：

  require_once('connection.php.inc');
  require_once 'Classes/PHPExcel/IOFactory.php';
  require_once 'Classes/PHPExcel.php';

  function HeaderingExcel($filename) {
      header("Content-type: application/vnd.ms-excel");
      header("Content-Disposition: attachment; filename=$filename" );
      header("Expires: 0");
      header("Cache-Control: must-revalidate, post-check=0,pre-check=0");
      header("Pragma: public");
      }

//-------upload---------------------------------------
error_reporting(E_ALL);

/** Include path **/
set_include_path(get_include_path() . PATH_SEPARATOR . './Classes/');

if (!file_exists($_FILES['excel_fajl']['tmp_name'])) {
    exit("Nije dobar fajl!");
}

$file =  $_FILES['excel_fajl']['tmp_name'];

$cacheMethod = PHPExcel_CachedObjectStorageFactory::cache_to_phpTemp;
$cacheSettings = array( 'memoryCacheSize' => '128MB');
PHPExcel_Settings::setCacheStorageMethod($cacheMethod,$cacheSettings);

$inputFileType = PHPExcel_IOFactory::identify($file);

$objReader = PHPExcel_IOFactory::createReader($inputFileType);

$objPHPExcel = $objReader->load($file);
$objPHPExcel-> setActiveSheetIndex(0);
$sheet = $objPHPExcel->getActiveSheet();

//kreiranje privremene tabele koju punimo:
$query1="create temp table visa_tc
(sequence char(170))
with no log";
odbc_exec($conn,$query1);
    
$i=1;
   foreach ($sheet->getRowIterator() as $row) {
    $sequence  = trim($sheet->getCellByColumnAndRow(0, $row->getRowIndex())->getValue());
    $query1 = "insert into visa_tc values ('".$sequence."')";
    odbc_exec($conn,$query1);
$i++;
      unset($sequence); 
    
  }
//--------kraj upload-a-------------------------------------
$query = "
SELECT sequence[17,20] Reason_code, sequence[24,27] Event_date, sequence[47,58]/100 dest_amount, sequence[59,61] destination_currency, 
       sequence[62,73]/100 source_amount, sequence[74,76] source_currency, sequence[77,146] message_text, 
       round(sequence[62,73]/sequence[47,58], 5) eur_usd, round(sequence[47,58]/sequence[62,73], 5) usd_eur
FROM visa_tc
WHERE sequence[17,20] <> ''";
$odbc_result = odbc_exec($conn,$query);


$excel = PHPExcel_IOFactory::createReader('Excel2007');
$excel = $excel->load('./TC_Template.xlsx'); // Empty Sheet

$excel->setActiveSheetIndex(0);

$i=3;
      while (odbc_fetch_row($odbc_result))
      {
        $excel->getActiveSheet(0)->getCellByColumnAndRow(1,  $i)->setValueExplicit(iconv('ISO-8859-2', 'utf-8//TRANSLIT',odbc_result($odbc_result,1)), PHPExcel_Cell_DataType::TYPE_STRING);
        $excel->getActiveSheet(0)->getCellByColumnAndRow(2,  $i)->setValueExplicit(iconv('ISO-8859-2', 'utf-8//TRANSLIT',odbc_result($odbc_result,2)), PHPExcel_Cell_DataType::TYPE_STRING);
        $excel->getActiveSheet(0)->getCellByColumnAndRow(3,  $i)->setValue(odbc_result($odbc_result,3));;
        $excel->getActiveSheet(0)->getCellByColumnAndRow(4,  $i)->setValueExplicit(iconv('ISO-8859-2', 'utf-8//TRANSLIT',odbc_result($odbc_result,4)), PHPExcel_Cell_DataType::TYPE_STRING);
        $excel->getActiveSheet(0)->getCellByColumnAndRow(5, $i)->setValue(odbc_result($odbc_result,5));
        $excel->getActiveSheet(0)->getCellByColumnAndRow(6, $i)->setValueExplicit(iconv('ISO-8859-2', 'utf-8//TRANSLIT',odbc_result($odbc_result,6)), PHPExcel_Cell_DataType::TYPE_STRING);
        $excel->getActiveSheet(0)->getCellByColumnAndRow(7, $i)->setValue(odbc_result($odbc_result,7));
        $excel->getActiveSheet(0)->getCellByColumnAndRow(8, $i)->setValue(odbc_result($odbc_result,8));
        $excel->getActiveSheet(0)->getCellByColumnAndRow(9, $i)->setValue(odbc_result($odbc_result,9));
        
                
                $i++;
        }

$k =$i+1;
  
$excel->getActiveSheet(0)->getCellByColumnAndRow(2, $k)->setValue('TOTAL:');
$excel->getActiveSheet(0)->SetCellValue('D'.$k,"=SUM(D3:D".($k-1).")");
$excel->getActiveSheet(0)->SetCellValue('F'.$k,"=SUM(F3:F".($k-1).")");

$filename = 'TC_VISA.xlsx';

header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="'.$filename.'"');
header('Cache-Control: max-age=0');
    
$objWriter = PHPExcel_IOFactory::createWriter($excel, 'Excel2007');
$objWriter->save('php://output');
exit;


       odbc_close($conn);
?>

这是必须上传到 table visa_tc

的 .txt 文件的内容

我从 sql 查询中获得的此列 'sequence[77,146]' 的输出基于此条目的示例：

10004083524334965010 06150000000000000000000000000014208978000000017180840VGBP BILLING FOR MAY 2021, INV 210500-13239- 0006, 421357 0611166479225089 11660

我应该得到的是：

VGBP BILLING FOR MAY 2021, INV 210500-13239- 0006, 421357

但我得到的是：

VGBP BILLING FOR MAY 2021

看起来序列在找到逗号时停止了。

我在代码中尝试了这个补救措施（preg_replace）

   foreach ($sheet->getRowIterator() as $row) {
    $sequence  = trim($sheet->getCellByColumnAndRow(0, $row->getRowIndex())->getValue());
    $query1 = "insert into visa_tc values ('".preg_replace('/[ ,]+/',' ',$sequence)."')";
    odbc_exec($conn,$query1);
$i++;
      unset($sequence); 
    
  }

and 

$i=1;
   foreach ($sheet->getRowIterator() as $row) {
    $sequence  = trim($sheet->getCellByColumnAndRow(0, $row->getRowIndex())->getValue());
    $sequence1 = preg_replace('/[,]+/', ' ', $sequence);
    $query1 = "insert into visa_tc values ('".$sequence1."')";
    odbc_exec($conn,$query1);
$i++;
      unset($sequence); 
    
  }

现在我希望我的问题更直接。

谢谢。

Answer 1

我找到了解决方案：

    exit("Nije dobar fajl!");
}

$file =  $_FILES['excel_fajl']['tmp_name'];
$handle = fopen($file, "r");

//kreiranje privremene tabele koju punimo:
$query1="create temp table visa_tc
(sequence char(170))
with no log";
odbc_exec($conn,$query1);


while (($buffer = fgets($handle, 4096)) !== false) {

$query1 = "insert into visa_tc values ('".$buffer."')";
odbc_exec($conn,$query1);
}

所以基本上，与原始代码相比唯一的区别是我添加了这个：

$handle = fopen($file, "r");

while (($buffer = fgets($handle, 4096)) !== false) {
$query1 = "insert into visa_tc values ('".$buffer."')";
odbc_exec($conn,$query1);
}

对我来说似乎不是一个相当大的要求。

谢谢！
