What potential pitfalls should be considered when importing CSV data into MySQL with PHP?

One potential pitfall when importing CSV data into MySQL with PHP is the risk of SQL injection if the CSV data is not properly sanitized before being inserted into the database. To mitigate this risk, it is important to use prepared statements with parameterized queries to safely insert the data into the database. 

// Establish a connection to the MySQL database
$pdo = new PDO("mysql:host=localhost;dbname=database_name", "username", "password");

// Prepare a SQL statement with placeholders
$stmt = $pdo->prepare("INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)");

// Parse the CSV file and insert data into the database
$csvFile = fopen('data.csv', 'r');
while (($data = fgetcsv($csvFile)) !== false) {
    $stmt->bindParam(':value1', $data[0]);
    $stmt->bindParam(':value2', $data[1]);
    $stmt->execute();
}
fclose($csvFile);
