Validating a service call Matures chat number

Validation is a very common task in web applications. Data also needs to be validated before it is written into a database or passed to a web service.Symfony provides a Validator component that makes this task easy and transparent.Constraints can also be applied to the return value of a method.Symfony allows you to add a constraint to any public method whose name starts with "get", "is" or "has".In Symfony, constraints are similar: they are assertions that a condition is true.Given a value, a constraint will tell you if that value adheres to the rules of the constraint. Property constraints are the most common and easy to use.When that class is validated, methods specified by that constraint are simply executed so that each can provide more custom validation.

The power behind validation lies in "constraints", which are rules that you can apply to properties or getter methods of your object.And while you'll most commonly use the validation framework indirectly when using forms, remember that it can be used anywhere to validate any object.
