How can the script be modified to ensure successful insertion of data into the MySQL table?

The script can be modified to ensure successful insertion of data into the MySQL table by adding error handling to catch any potential errors that may occur during the insertion process. This can be done by using the `mysqli_error()` function to display any error messages that are returned by MySQL. Additionally, using prepared statements can help prevent SQL injection attacks and improve the overall security of the script. 

// Connect to MySQL database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Check connection
if (!$connection) {
    die("Connection failed: " . mysqli_connect_error());
}

// Prepare and bind SQL statement
$stmt = $connection->prepare("INSERT INTO table_name (column1, column2) VALUES (?, ?)");
$stmt->bind_param("ss", $value1, $value2);

// Set parameter values
$value1 = "value1";
$value2 = "value2";

// Execute the statement
if ($stmt->execute()) {
    echo "Data inserted successfully";
} else {
    echo "Error: " . $stmt->error;
}

// Close statement and connection
$stmt->close();
$connection->close();
