Too late at night - but this should get you started .


$z1=(rand()%9)+1;
$z2=(rand()%9)+1;

$z3=$z1+$z2;

$z1 + $z2 = <input type="text" name="summ" size="25">

<input type="hidden" name="demo" size="0" value="<?php print $z3; ?>">


On the next page .....

$aaa=$_POST['summ'];
$bbb=$_POST['demo'];

if ($aaa<>$bbb) {print "take a hike spammer <br>";}
