Are there any specific best practices recommended for using filter_var() in PHP for different data validation scenarios?

When using filter_var() in PHP for data validation, it is recommended to specify the appropriate filter for the type of data being validated. This helps ensure that the input matches the expected format. Additionally, it's important to handle the return value of filter_var() properly, as it may return false if the input fails validation.

// Example of using filter_var() for email validation
$email = "test@example.com";
if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
    echo "Email is valid";
} else {
    echo "Email is not valid";
}
