Data Validation class

Screenshots

The key to a stable and secure application or website is data validation. Validating things like email addresses, numbers, and other data can be very time consuming and add a lot of extra lines of code to your website if you want to do it the right way. This class can make the data validation part of website development a lot easier.

This class is very easy to use. Because all the methods are static they are faster and callable without instantiating the class. This will say that you only need to include the PHP file in your code and do the validations like below. The method returns a boolean (true when it’s valid, false when invalid). To show you some examples:

Email validation:

if(!Validator::Email("wim(at)test.com")){
    echo "Your email is invalid";
}

Email validation and don’t accept addresses that end with test.com or test.be:

if(!Validator::Email("wim(at)test.com", array("test.com", "test.be"))){
    echo "Your email is invalid";
}

Check if a number is between 20 and 50:

if(!Validator::Number(35, 50, 20)){
    echo "The number is not between 20 and 50";
}

Check if a user is older than 18:

if(!Validator::OlderThan("1966-2-5", 17)){
    echo "You must be older than 18.";
}
