comment utiliser phpexcel pour lire des données et les insérer dans une base de données?
J'ai une application php où je veux lire des données à partir d'Excel, insérer dans une base de données, puis générer des rapports au format PDF pour des utilisateurs spécifiques . si quelqu'un pouvait fournir un tutoriel ou quelque chose du genre, ce serait une aide réelle.
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 le reste devient très dépendant de votre base de données et de la manière dont vous voulez que les données y soient structurées.
Afin de lire les données de Microsoft Excel 2007 par codeigniter, il suffit de créer une fonction d'assistance Excel_helper.php et d'ajouter les éléments suivants dans:
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);

En utilisant la bibliothèque 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
$i++;
}
if($this->mng_auth->get_language()=='en')
{
$Excel->getActiveSheet()->setRightToLeft(false);
}
else
{
$Excel->getActiveSheet()->setRightToLeft(true);
}
$styleArray = array(
'borders' => array(
'allborders' => array(
'style' => PHPExcel_Style_Border::BORDER_THIN,
'color' => array('argb' => '00000000'),
),
),
);
//SET property
$objPHPExcel->getActiveSheet()->getStyle('A1:M10001')->applyFromArray($styleArray);
$objPHPExcel->getActiveSheet()->getStyle('A1:M10001')->getAlignment()->setWrapText(true);
$objPHPExcel->getActiveSheet()->getStyle('A1:'.chr(65+count($fields)-1).$query->num_rows())->applyFromArray($styleArray);
$objPHPExcel->getActiveSheet()->getStyle('A1:'.chr(65+count($fields)-1).$query->num_rows())->getAlignment()->setWrapText(true);
