Property

• Property(string $propertyName, Validator $validator)

Validates an object property against a given validator.

$object = new stdClass;
$object->name = 'The Respect Panda';
$object->email = 'therespectpanda@gmail.com';

v::property('name', v::equals('The Respect Panda'))->assert($object);
// Validation passes successfully

v::property('email', v::email())->assert($object);
// Validation passes successfully

v::property('email', v::email()->endsWith('@example.com'))->assert($object);
// → `.email` must end with "@example.com"

You can also use Property to validate nested objects:

$object = new stdClass();
$object->address = new stdClass();
$object->address->postalCode = '1017 BS';

v::property(
    'address',
    v::property('postalCode', v::postalCode('BR'))
)->assert($object);
// → `.address.postalCode` must be a valid postal code on "BR"

Note

This validator will validate public, private, protected, uninitialised, and static properties.

• To only validate if a property exists, use PropertyExists instead.
• To validate a property against a given validator only if the property exists, use PropertyOptional instead.
