What are the potential pitfalls of using a text file to store IP, time, and username data in PHP?

The potential pitfalls of using a text file to store IP, time, and username data in PHP include security vulnerabilities, scalability issues, and potential data corruption if multiple users write to the file simultaneously. To solve this, it is recommended to use a database like MySQL to store this type of data securely and efficiently. 

// Connect to MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
