[RESOLVED] Adding up values in a for loop

[7724]

Hello,

If I had a for loop like so

if ($_POST['Submit']) {

for ($i = 0; $i < count($_POST['amount']); $i++) {
echo "<p>{$_POST['amount][$i]}</p><br/>";
}

}

How could I keep a tally of all these and output the total when the loop has finished?

you do not need a for nor a foreach loop for this

$_POST['amount'] = array(1,2,3,4,5,6,7,8,9);

echo implode('<br>', $_POST['amount']);
echo '<br>and the sum is ' . array_sum($_POST['amount']);

Thanks for that.
