Code: Select all

$lo = 2;
$high = 7;
echo $lo < $high;

The above code outputs 1.

However,

Code: Select all

echo $lo < $high . " string";

doesn't concatenate " string" to that 1. Why is that?

I know there is a better way of doing all of the above, but I'm just trying to understand the concatenation issue.

Thanks!
