similar_text - Calculate the similarity between two strings

SYNOPSIS
int similar_text (string $first, string $second, [float &$percent])
DESCRIPTION
This calculates the similarity between two strings as described in Programming Classics: Implementing the World's Best Algorithms by Oliver (ISBN 0-131-00413-1). 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.
PARAMETERS
o $first - The first string. o $second - The second string. o $percent - By passing a reference as third argument, similar_text(3) will calculate the similarity in percent for you.
RETURN VALUES
Returns the number of matching chars in both strings.
