What are some recommended methods for ensuring that data from an Excel document is correctly placed in a database using PHP?

When transferring data from an Excel document to a database using PHP, it is important to ensure that the data is correctly formatted and placed in the appropriate database fields. One recommended method is to use a PHP library like PHPExcel to read the Excel file and extract the data, then use prepared statements to insert the data into the database to prevent SQL injection attacks. 

// Include PHPExcel library
require_once 'PHPExcel/Classes/PHPExcel.php';

// Load the Excel file
$objPHPExcel = PHPExcel_IOFactory::load('example.xlsx');

// Get the active sheet
$sheet = $objPHPExcel->getActiveSheet();

// Loop through rows and insert data into database
foreach ($sheet->getRowIterator() as $row) {
    $rowData = $row->getWorksheet()->rangeToArray('A' . $row->getRowIndex() . ':' . $row->getHighestDataColumn() . $row->getRowIndex(), NULL, TRUE, FALSE);
    
    // Insert data into database using prepared statements
    $stmt = $pdo->prepare("INSERT INTO table_name (column1, column2) VALUES (?, ?)");
    $stmt->execute([$rowData[0][0], $rowData[0][1]]);
}
