What potential pitfalls should be considered when transferring data from text files to a MySQL database using PHP?

One potential pitfall to consider when transferring data from text files to a MySQL database using PHP is ensuring that the data is properly sanitized to prevent SQL injection attacks. It is important to escape special characters in the data before inserting it into the database to avoid any security vulnerabilities. 

// Read data from text file
$data = file_get_contents('data.txt');

// Sanitize data before inserting into MySQL database
$escaped_data = mysqli_real_escape_string($connection, $data);

// Insert sanitized data into MySQL database
$query = "INSERT INTO table_name (column_name) VALUES ('$escaped_data')";
mysqli_query($connection, $query);
