php-symfonyAssert usage with PHP Symfony

Assert is a PHP library that provides a set of assertion methods for validating the input of a Symfony application. It is part of the Symfony PHPUnit Bridge and is used to validate the input of a Symfony application.

Example code

use Symfony\Component\Validator\Constraints as Assert;

class User
{
    /**
     * @Assert\NotBlank()
     */
    public $name;
}

The example code above uses the @Assert\NotBlank() annotation to validate that the name property of the User class is not blank.

Code explanation

• use Symfony\Component\Validator\Constraints as Assert;: This imports the Assert namespace from the Symfony\Component\Validator namespace.
• @Assert\NotBlank(): This is an annotation that is used to validate that the name property of the User class is not blank.
