use \Inputrender\InputRender; $input = new InputRender('text', 'username'); $input->setLabel('Username'); $input->setPlaceholder('Enter your username'); $input->setRequired(true); $input->setMinLength(4); $input->setMaxLength(20); if ($input->validate($_POST['username'])) { // Success, handle input } else { // Error validation, handle error }In this example, we have set some validation rules for the input field. We have made the field required, set the minimum length and maximum length of the input string. Then, we validate the input using the `validate` method by passing the submitted value of the input field from `$_POST` superglobal variable. If validation passes, it means the user input is valid, and we can perform some action using the value. If it fails, an error message can be displayed to the user. Based on the naming conventions, it seems that this library is not associated with any popular PHP framework or CMS. The package name could be `inputrender/inputrender`.
