Question

I have a PHP variable that looks a bit like this:

$id = "01922312";

I need to replace the last two or three numbers with another character. How can I go about doing this?

EDIT Sorry for the confusion, basically I have the variable above, and after I’m done processing it I’d like for it to look something like this:

$new = "01922xxx";

Answer 1

Try this:

$new = substr($id, 0, -3) . 'xxx';

Result:

01922xxx
