This class can validate an option of a select input with its HTML.
It can take the HTML used to display a form select input and parses it to check if a given option makes part of the defined options.
The class can also extract the list of all available options and return an array with all the option values.
|All the applications that generate HTML for the forms they present to their users know what are the valid options that the users may pick for select inputs.
However, when the applications use HTML for select input provided from other sources, the list of valid options depends on other applications that generated the HTML for the form.
This class provides a solution for validating forms with select inputs that are displayed using HTML provided by third-party applications that consist in parsing the HTML of the form select input to extract the list of valid options.

what is this ?
when you are using a long select box in your website for example country selectbox or city selectbox or any other static selectbox user can simple edit the value of a option and send it to the backend and create alot of problem . users can attack your website using this method.
