How to use one validator?

$validator = new IsEmailValidator();
$result = $validator->valid('email@gmail.com');

//  $result contains 0 when evrything is ok
//  or value > 1 otherwise

How to check value with many validators?

validThroughAllValidators() method checks given value in ALL validators.

$collection = new ValidatorsCollection(
    [
        new IsNotNullValidator(),
        new IsEmailValidator(),
    ]
);

$result = $collection->validThroughAllValidators('email@gmail.com');

$result->isValid();     // returns true if value is passed thought all validators
$result->errors();      // returns array of error numbers for each of not-passed validators

validToFirstError() method checks given value in all validators TO FIRST FAIL.

$collection = new ValidatorsCollection(
    [
        new IsNotNullValidator(),
        new IsEmailValidator(),
    ]
);

$result = $collection->validToFirstError('email@gmail.com');

$result->isValid();     // returns true if value is passed thought all validators
$result->errors();      // returns array of error numbers (in this case there will be only single element in array) for each of not-passed validators

How to check array of values?

You can create array full of validators. This array can contain nested validators arrays:

$validators = [
    "email" => new IsEmailValidator(),
    "age" => new IsNumberValidator()
];

This $validators array can be used to validate $data array:

$data = [
    "email" => "incorrect email address",
    "age" => 35
];

$arrayValidator = mew ArrayValidator(); 
$result = $arrayValidator->validateArray($validators, $data);

$result variable contains ValidationResult objects. ValidationResult::errors() returns nested array with error codes.

For more example look into ./tests/unit/ArrayValidatorTest.php
