Are there alternative methods to validating and sanitizing email content in PHP without using regular expressions?

When validating and sanitizing email content in PHP without using regular expressions, one alternative method is to utilize PHP's built-in filter_var function with the FILTER_VALIDATE_EMAIL filter. This function can validate an email address based on its format. To sanitize email content, you can use the filter_var function with the FILTER_SANITIZE_EMAIL filter, which will remove any characters that are not allowed in an email address. 

$email = "example@example.com";

// Validate email address
if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
    echo "Email is valid";
} else {
    echo "Email is not valid";
}

// Sanitize email address
$sanitizedEmail = filter_var($email, FILTER_SANITIZE_EMAIL);
echo $sanitizedEmail;
