   (PHP 3>= 3.0.7, PHP 4 )
   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.
