How can special characters like quotation marks be properly handled during data import in PHP?

Special characters like quotation marks can be properly handled during data import in PHP by using prepared statements when interacting with a database. Prepared statements automatically escape special characters, preventing SQL injection attacks and ensuring that the data is imported correctly. This helps to avoid any issues with special characters causing errors or unexpected behavior during the import process.

// Assuming $pdo is your PDO connection object and $data is the data to be imported

$stmt = $pdo->prepare("INSERT INTO table_name (column_name) VALUES (:data)");
$stmt->bindParam(':data', $data);
$stmt->execute();
