Hi, I really can't understand why this echo "321"?? I guess echo "123". But correct answer is "321"...
In "Building a Basic PHP Website"
<?php
$numbers = array(1,2,3,4);
$total = count($numbers);
$sum = 0;
$output = "";
$i = 0;
foreach($numbers as $number) {
$i = $i + 1;
if ($i < $total) {
$output = $number . $output;
}
}
echo $output;
?>
please help...

7,907 PointsHi,
The reason that the numbers are returned as '3,2,1' is because of $output is being concatenated to the end each time. So the first time the foreach loop runs it will output
1
The second loop will get the next number and then concatenate the previous number to the end for example:
2,1
And then again with the last number:
3,2,1
To get it to output the numbers in order you would need to do the following:
$output .= $number
I hope that helped you :)
