similar_text --
Calculate the similarity between two strings
Description
int
similar_text ( string first, string second [, float percent])
This calculates the similarity between two strings as described
in Oliver [1993]. Note that this implementation does not use a
stack as in Oliver's pseudo code, but recursive calls which may
or may not speed up the whole process. Note also that the
complexity of this algorithm is O(N**3) where N is the length of
the longest string.
By passing a reference as third argument,
similar_text() will calculate the similarity
in percent for you. It returns the number of matching chars in
both strings.
