so, when i click the button 'choose' for example, the computer will choose anyone of A, B, C..... (computer/machine will choose randomly)...

please help me.....

thanks....

 

here is small code example on how to use random:

// setup an array of options
$a = array('A', 'B', 'C');
// get a random number between 0 and the number of items in the above array (-1)
$i = rand(0, count($a)-1);
// print the value
echo $a[$i];

 

There's a function called array_rand(), which is made for this purpose. No need to use count() and rest one.
