symfony/validator v7.0.6

The Symfony/Validator is an advanced tool that assists in validating values in accordance with the JSR-303 Bean Validation specification. Its primary function is to ensure that all input values comply with the set standards and rules for data integrity and accuracy.

The Symfony/Validator package is utilized by incorporating it into PHP scripts in order to examine values and ensure they adhere to specified data rules. To use this tool, you must first install it using composer. The command composer require symfony/validator will add the package to your project. After the installation, you can use it by calling the necessary functions.

Here is a simple usage example:

use Symfony\Component\Validator\Validation;
use Symfony\Component\Validator\Constraints\Length;

$validator = Validation::createValidator();
$violations = $validator->validate('Hello World!', new Length(['min' => 5, 'max' => 10]));
if (0 !== count($violations)) {
    foreach ($violations as $violation) {
        echo $violation->getMessage(). "\n";
    }
}

This script checks if the text 'Hello World!' is between 5 and 10 characters.
