Wie verwende ich phpexcel, um Daten zu lesen und in die Datenbank einzufügen?

Ich habe eine phpAnwendung, in der ich Daten aus Excel lesen, in eine Datenbank einfügen und dann PDF-Berichte für bestimmte Benutzer erstellen möchte. Ich habe viel gesucht, aber nichts Spezielles zu beiden Dingen.

Verwenden der PHPExcel-Bibliothek zum Lesen einer Excel-Datei und zum Übertragen der Daten in eine Datenbank

//  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
}

Alles andere hängt stark von Ihrer Datenbank ab und davon, wie die Daten darin strukturiert sein sollen

Um Daten von Microsoft Excel 2007 per Codeigniter zu lesen, erstellen Sie einfach eine Hilfsfunktion excel_helper.php und fügen Sie Folgendes hinzu:

      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);

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

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