What are the best practices for using prepared statements in PHP to avoid errors like "No data supplied for parameters"?

When using prepared statements in PHP, it's crucial to ensure that all parameters are bound correctly before executing the query. To avoid errors like "No data supplied for parameters", make sure to bind all parameters to the prepared statement before executing it. This ensures that all placeholders in the query have corresponding values provided. 

// Example code snippet to avoid "No data supplied for parameters" error
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username AND email = :email");

// Bind parameters
$stmt->bindParam(':username', $username);
$stmt->bindParam(':email', $email);

// Execute the query
$stmt->execute();
