Synopsis
int levenshtein(stringone, stringtwo[, intinsert, intreplace,intdelete]) int levenshtein(stringone, stringtwo[, mixedcallback])
Calculates the Levenshtein distance between two strings. This is
the number of characters you have to replace, insert, or delete to
transform one into
two. By default, replacements, inserts, and
deletes have the same cost, but you can specify different costs with
insert, replace,
and delete. In the second form, just the
total cost of inserts, replaces, and deletes are returned, not broken
down.
