What are the best practices for handling conditional statements in PHP to ensure accurate data insertion into a database?

When handling conditional statements in PHP to ensure accurate data insertion into a database, it is important to properly validate and sanitize user input before inserting it into the database. This can help prevent SQL injection attacks and ensure that only valid data is inserted. Using prepared statements with parameterized queries is a best practice for securely inserting data into a database in PHP. 

// Assuming $conn is your database connection

// Validate and sanitize user input
$name = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
$email = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL);

// Prepare and execute a parameterized query
$stmt = $conn->prepare("INSERT INTO users (name, email) VALUES (?, ?)");
$stmt->bind_param("ss", $name, $email);

if ($stmt->execute()) {
    echo "Data inserted successfully";
} else {
    echo "Error inserting data: " . $conn->error;
}

$stmt->close();
$conn->close();
