Description: ------------ Class names such as 'True' and 'False' are incorrectly detected as mixed case constants by the LowerCaseConstantSniff. An example block of code from a real world application follows, running the PSR2 ruleset against it results in a false error being raised against the use of the Symfony True constraint object. PHP version is CentOS6.4 default package version of 5.3.3. Test script: --------------- use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; use Symfony\Component\Validator\Constraints\True; class MyFormType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder->add( 'propertyName', 'checkbox', array( 'constraints' => new True( array( 'message' => 'Constraint message' )),));}} Expected result: ---------------- Running the PSR2 ruleset against the provided code should not consider the True constraint object to be a constant. Actual result: -------------- Running the PSR2 ruleset against the provided code presents the error: 'TRUE, FALSE and NULL must be lowercasecase; expected "true" but found "True"'
