I am making a quiz application where I have a multiple choice question in PHP. The user gets a question and multiple choices to select the answers. The options what they get will refresh (shuffle/ rand func) everytime. So when the user selects the checkbox and the options gets verified with the correct answer and score them. E.g. if there are 3 right choices and user selects all 3 correct they get 5 points and partial correct they get 3 points and for wrong selections they get 0. Please find my code below. Thanks for your time,
