random variable

[kpdvx]

I have four variables.
$answer1, $answer2, $answer3 and $rightanswer.

I have a set of radio buttons.
<INPUT TYPE=RADIO NAME=&quot;guess&quot; VALUE=&quot;1&quot;>answer<BR>
<INPUT TYPE=RADIO NAME=&quot;guess&quot; VALUE=&quot;2&quot;>answer<BR>
<INPUT TYPE=RADIO NAME=&quot;guess&quot; VALUE=&quot;3&quot;>answer<BR>
<INPUT TYPE=RADIO NAME=&quot;guess&quot; VALUE=&quot;4&quot;>answer<BR>

I want to put those variable names in randomly so that each time the correct answer is different. Is there any way to do this.. and allow for me to know which radio button was clicked?

your question is not very clear - but you can use the code below for writing a random text string to the html code using php.

--------------

$anames = array('answer1', 'answer2', 'answer3', 'answer4');

srand ( (double) microtime() * 1000000);
// when generating a random number, be sure to use srand() only once in the script, not more. (do not include srand inside a loop of any kind)

$r = rand(0,3);
// rand() syntax: rand(lowestnumber,highestnumber);

$name = $anames[$r];

print('<INPUT TYPE=RADIO NAME=&quot;guess&quot; VALUE=&quot;1&quot;>' . $name . '<BR>');
