You have your answer, just use this:
$outstring = eregi_replace("badword","goodword",$stringtocheck);
It'll replace it whether it's at the beginning or end of a string, embedded
in a word, or by itself. Isn't that what you want?
Actually, it'd be better and faster to just use str_replace() instead of a
regular expression...
