Question

Is there a function to hide the last 2-3 digits in an IP so it shows

127.0.0.xxx

For example?

I know of str_replace, but that can’t be used for this, or can it? =P

Answer 1

$text = preg_replace('/([0-9]+\\.[0-9]+\\.[0-9]+)\\.[0-9]+/', '\\1.xxx', $text);

is the solution I would choose because I’m comfortable with regular expressions and then it shows immediately what it’s doing. There are several other possibilities.
