I looked at the 'sound like' modules in php (leveshtien, soundex) but they are
for comparing 2 strings, not creating a string based on what we already have.

I see that str_replace supports regular expessions. Without devoting hours
learning to write a regex, would it be inappropriate for me to ask how would
a regex look that basically says to str_replace "replace the n-th occurence
of $was with $willbe" and then I could just loop n==1 n==2 until
n==substr_count($data, $was);

Did I mention how much I appreciate your help in this matter? I am very
impress with the wealth of information the php community is willing to share.
