comment utiliser phpexcel pour lire les données et les insérer dans la base de données ?

Question

J'ai un php Une application où je veux lire les données d'Excel, les insérer dans la base de données et ensuite générer des rapports pdf pour des utilisateurs spécifiques. J'ai beaucoup cherché sur Internet mais rien de précis n'a été donné sur ces deux sujets. Si quelqu'un pouvait fournir un tutoriel ou quelque chose, ce serait une vraie aide.

Answer 1

Utilisation de la bibliothèque PHPExcel pour lire un fichier Excel et transférer les données dans une base de données

//  Include PHPExcel_IOFactory
include 'PHPExcel/IOFactory.php';

$inputFileName = './sampleData/example1.xls';

//  Read your Excel workbook
try {
    $inputFileType = PHPExcel_IOFactory::identify($inputFileName);
    $objReader = PHPExcel_IOFactory::createReader($inputFileType);
    $objPHPExcel = $objReader->load($inputFileName);
} catch(Exception $e) {
    die('Error loading file "'.pathinfo($inputFileName,PATHINFO_BASENAME).'": '.$e->getMessage());
}

//  Get worksheet dimensions
$sheet = $objPHPExcel->getSheet(0); 
$highestRow = $sheet->getHighestRow(); 
$highestColumn = $sheet->getHighestColumn();

//  Loop through each row of the worksheet in turn
for ($row = 1; $row <= $highestRow; $row++){ 
    //  Read a row of data into an array
    $rowData = $sheet->rangeToArray('A' . $row . ':' . $highestColumn . $row,
                                    NULL,
                                    TRUE,
                                    FALSE);
    //  Insert row data array into your database of choice here
}

Tout ce qui est plus dépend de votre base de données, et de la façon dont vous voulez que les données soient structurées.

Afin de lire les données de microsoft excel 2007 par codeigniter, il suffit de créer une fonction d'aide excel_helper.php et d'y ajouter ce qui suit :

      require_once APPPATH.'libraries/phpexcel/PHPExcel.php';
      require_once APPPATH.'libraries/phpexcel/PHPExcel/IOFactory.php';
      in controller add the following code to read spread sheet by active sheet
     //initialize php excel first  
     ob_end_clean();
     //define cachemethod
     $cacheMethod   = PHPExcel_CachedObjectStorageFactory::cache_to_phpTemp;
     $cacheSettings = array('memoryCacheSize' => '20MB');
     //set php excel settings
     PHPExcel_Settings::setCacheStorageMethod(
            $cacheMethod,$cacheSettings
          );

    $arrayLabel = array("A","B","C","D","E");
    //=== set object reader
    $objectReader = PHPExcel_IOFactory::createReader('Excel2007');
    $objectReader->setReadDataOnly(true);

    $objPHPExcel = $objectReader->load("./forms/test.xlsx");
    $objWorksheet = $objPHPExcel->setActiveSheetIndexbyName('Sheet1');

    $starting = 1;
    $end      = 3;
    for($i = $starting;$i<=$end; $i++)
    {

       for($j=0;$j<count($arrayLabel);$j++)
       {
           //== display each cell value
           echo $objWorksheet->getCell($arrayLabel[$j].$i)->getValue();
       }
    }
     //or dump data
     $sheetData = $objPHPExcel->getActiveSheet()->toArray(null,true,true,true);
     var_dump($sheetData);

     //see also the following link

    $highestRow         = $worksheet->getHighestRow(); // e.g. 10
    $highestColumn      = $worksheet->getHighestColumn(); // e.g 'F'
    $highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
    $nrColumns          = ord($highestColumn) - 64;
    $worksheetTitle     = $worksheet->getTitle();

    echo "<br>The worksheet ".$worksheetTitle." has ";

Answer 3

Utilisation de la PHPExcel le code suivant fera l'affaire.

require_once dirname(__FILE__) . '/../Classes/PHPExcel/IOFactory.php';    
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objReader->setReadDataOnly(true); //optional

$objPHPExcel = $objReader->load(__DIR__.'/YourExcelFile.xlsx');
$objWorksheet = $objPHPExcel->getActiveSheet();

$i=1;
foreach ($objWorksheet->getRowIterator() as $row) {

    $column_A_Value = $objPHPExcel->getActiveSheet()->getCell("A$i")->getValue();//column A
    //you can add your own columns B, C, D etc.

    //inset $column_A_Value value in DB query here

    $i++;
}

        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
        $objWriter->save('php://output');
