$mysql_connect("host", "user", "pwd");
$result = $mysql_db_query("vpt",
"SELECT id, txt FROM questions "
."ORDER BY RANDOM() LIMIT 10"
);
function makeQuestion($qid) {
return (
"<input type='radio' name='q[$qid]' value=1>1"
."<input type='radio' name='q[$qid]' value=2>2"
."<input type='radio' name='q[$qid]' value=3>3"
."<input type='radio' name='q[$qid]' value=4>4"
."<input type='radio' name='q[$qid]' value=5>5"

}
function makeRow() {
$str = "\n\t<tr>";
$num = func_num_args();
for ($i = 0; $i < $num; $i++)
$str .= "\n\t\t<td>".func_get_arg($i)."</td>";
$str .= "\n\t</tr>";
return $str;
}
echo "\n<form>\n<table>";
while ($row = mysql_fetch_array($result))
echo makeRow(makeQuestion($row[id]), $row[txt]);
echo makeRow("<input type='reset'>", "<input type='submit'>");
echo "\n</table>\n</form>";
Voila - they get ten questions at random, in random order;
when they submit the form, you get the question id back as
the array key and the answer as the value.
Hope that helps ;-)
