random order

[SleePy]

Hello,
I am scripting up a random quiz that my users on my site wanted for some odd reason. i needed to randomize the order of the questions.
basically i got code like

$q[#] = 'htmlcode';

were # is a number that i increase for each question. i didn't feel like making a mysql table to hold the questions and answers.

and then i got

for ($i = 0; $i < 28; $i++)
	echo '<tr><td  align="left" valign="top">'. $q[$b++]. '</td></tr>';

but they come out in order. how would i randomize the order of the questions?? i know i can use the php code to do a random string but i do not want the same questions appearing twice. So thats where i am stumped on what to do.
Any Idea?
Thanks.

This might work... utterly untested tho...

$rand_keys = array_rand($q, 28);
for ($i = 0; $i < 28; $i++)
	echo '<tr><td  align="left" valign="top">'. $q[$rand_keys[$i]]. '</td></tr>';

Hey, Thanks
A little tweaking to make it work with my code and that did the job 🙂
Thank you very much

Well, the easiest way would be to do something like:

<?php

$q = array(); // Your array of questions

// Randomize it:
shuffle($q);

// Loop it:
foreach($q as $huh)
{
  echo $huh.'<br>';
}
?>

This helps to reduce the redundancy of questions (like asking the same question 3 times in a 10 question set).
