similar_text
Calculate the similarity between two strings
(PHP 4, PHP 5)
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.
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.
