similar_text() - string

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 : 
 first - The first string. 
 second - The second string. 
 percent - By passing a reference as third argument,
       similar_text() will calculate the similarity in
       percent for you. 

Syntax

int similar_text
    ( string $first
   , string $second
   [, float &$percent
  ] )
