the simplest problem in the world!

what is wrong here?

$text = "ab";
$new = substr($text, 0, 1) + substr($text, 1, 1);

$new should be "ab" but instead it's 0. I think it has to do with how I add two strings to eachother... i use a + but I guess that is wrong....

• is a mathcematical operation.

try

$new = substr($text, 0, 1).substr($text, 1, 1);

"+" sumarizes NUMBERS. "." concatenates strings.

$new = substr($text, 0, 1).substr($text, 1, 1);
