PHP mysql import data through excel - php

Question

I want to import data using php mysql from excel sheet containing 1.6 million records. What is the best way to do this?
this is the sample code I have used to iterate excel file and insert data in database:
public function iterateData($file_name) {
$fileDirectory = '';
$file_name = $fileDirectory . $file_name;
if (file_exists($file_name)) {
$this->truncateTable();
include 'PHPExcel2/Classes/PHPExcel/IOFactory.php';
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objPHPExcel = $objReader->load($file_name);
$count = 1;
foreach ($objPHPExcel->getWorksheetIterator() as $worksheet) {
foreach ($worksheet->getRowIterator() as $row) {
$cellIterator = $row->getCellIterator();
$cellIterator->setIterateOnlyExistingCells(true); // Loop all cells, even if it is not set
$cellValues = array();
foreach ($cellIterator as $cell) {
if (!is_null($cell)) {
$cellValues[] = $cell->getCalculatedValue();
}
}
if (isset($cellValues[0]) && $cellValues[0] != 'Product' && $cellValues[0] != '') {
$this->inserInDatabase($cellValues);
} elseif (empty($cellValues[0]) && empty($cellValues[1]) && empty($cellValues[2])) {
continue;
}
}
if ($objPHPExcel->getSheetCount() == $count) {
return TRUE;
}
$count++;
}
} else {
return FALSE;
}
} private function inserInDatabase($data) {
$dbDetails = array(
'db_name' => '*',
'db_pass' => '*',
'db_host' => 'localhost',
'db_user' => '*'
);
$dbh = dbConnect::connect($dbDetails);
$date = date('Y-m-d H:i:s');
$sql = "INSERT INTO product_description (product_id, prpoduct_description, price, created_date) values ('" . mysql_escape_string($data[0]) . "', '" . mysql_escape_string($data[1]) . "', '" . mysql_escape_string($data[2]) . "', '$date')";
if (!$dbh->dbh->query($sql)) {
die('Database Connection Failed.');
}
}

Answer 1

export you excel data to csv format, and then import the csv format to mysql

Answer 2

you can import using ;
if($request->hasFile('excelFile')){
$inputFileType = 'Xlsx';
$inputFileName = $request->file('excelFile')->getRealPath();
/** Create a new Reader of the type defined in $inputFileType **/
$reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader($inputFileType);
/** Advise the Reader that we only want to load cell data **/
$reader->setReadDataOnly(true);
/** Load $inputFileName to a Spreadsheet Object **/
$spreadsheet = $reader->load($inputFileName);
foreach ($spreadsheet->getActiveSheet()->toArray() as $key => $row) {
$data['question'] = $row[0];
$data['option1'] = $row[1];
$data['option2'] = $row[2];
$data['option3'] = $row[3];
$data['option4'] = $row[4];
$data['correct'] = $row[5];
$data['status'] = 1;
$data['receiver'] = 'all';
$data['createdOn'] = date("Y-m-d H:i:s");
if(!empty($data)) {
DB::table('questions')->insert($data);
}
}
}
