Perl Amperstamp Filter? How to change & in to &?

[JAB Creations]

How do I filter amperstamps to instead be written as &?

Like this?

$string =~ s/&/&/g

Righteous! Righteous!

Thank you so much zCat! :)

what will happen if the string already contains &? you will get &

You can use?! to not match & followed by amp;

$string =~ s/&(?!amp;)/&/ig; 

but if you are sure there will never be & in the string then just use the regexp already posted.

$string =~ s/&(?!amp;)/&/ig;

Just want to confirm with smilies disabled?

What the heck is an amperstamp [google.com]? "&" is an ampersand [google.com]...
