Rand

[Anon]

Im stuck on how to use the rand function with a input form

What im doing is lets say I enter 20 into the input form then hit the submit button.

I want it to proccess a random function.

The random function should random numbers from 0-9 but loop as many times as you put into the input form. so the rand() should loop 20 times. I want the output the rand() puts out each time and have it add up after all the loops.

I am not sure on how to do this.

I know

srand((double)microtime()*1000000);
$randval = rand(0, 9);

well work but how to get it so it will loop as many times you say it to from the input form (in this case 20 times) then add all the results from each loop

Use some operators...
<?
srand((double)microtime()*1000000);

for ($i=0;$i<$inputValue;$i++) {
$randval += rand(0,9);
}
?>

hummm this works only that the output string is way to long.

lets say I enter in 80

it will come up with
