PHP Quiz Script

Hard coding a graded quiz script in PHP

Quizzes are generally used to test knowledge of a subject.
This is a simple script that will allow you to create a quiz and grade the answers given.

PHP Code:

<?php
$let=array(
"a","b","c","d","e","f","g","h","i",
"j","k","l","m","n","o","p","q","r",
"s","t","u","v","w","x","y","z"
);
 
//Set a counter to 1
$count = 1;
 
/* What is a perfect score? Usually 100. */
 
$psco=100;
 
/* Deduction for each wrong answer. May be the perfect score divided by the number of questions

Populating checkboxes and select lists from an array

When you use checkboxes in a form, usually you want to save more than one choice.
You must indicate to PHP that you are submitting more than one piece of data with []

<INPUT TYPE="checkbox" NAME="temperature[]" VALUE="hot">Hot
<INPUT TYPE="checkbox" NAME="temperature[]" VALUE="cold">Cold

After submitting your form, save the array data into database.
You can use the implode function joins array elements into a string, then save that string to the
database.
