Random Question Generator

[NotVeryTechie]

Hi there

I would love to put a Random Question on our forms, similar to the one on this site (registration). How do I start, what validation would I need to create - bearing in mind that I am so new to this I am still trying to work out what php is. :o

Hope you can help.

Hello NotVeryTechie, a very simple way of doing this is by using this logic.

Create an array of questions (below I used 3 questions), and select a random id from the array using rand(), and then print out the value.

$QuestionArray = new array(3);
$QuestionArray[0] = 'Question 1?';
$QuestionArray[1] = 'Question 2?';
$QuestionArray[2] = 'Question 3?';

$myRandomNumber = rand(0, 2);

echo $QuestionArray[$myRandomNumber];

I hope this helps!

Oh my, daynah, you're back!

Unfortunately, I note that array(3) creates an array with one element, namely, 3. A somewhat better example would be:

$QuestionArray = new array(
    'Question 1?',
    'Question 2?',
    'Question 3?');

echo $QuestionArray[array_rand($QuestionArray)];

Wow, thanks, do I just put this in my form in the place where I want the question to appear? Do I put the question after 'Question 1?' or in a different place?

Thanks for the help

Replace the words Question 1 with your own question.

Note that you will want another array containing answers.
