Hey guys,

Got a newbie and embarrassing question....

I thought that the ++ would add 1 to a number? Like so:

Code:

$test = 1;

$test2 = $test++;

echo "OUTPUT: $test2";

The output is still 1. I thought that the output should be 2?

Is the only way to use the ++ is in loops?

I thought that the ++ was a quick way to add "1" without having to do this:

$test2 = ($test + 1);
