metaphone

(PHP 4 )

metaphone -- Calculate the metaphone key of a string

Description

string metaphone ( string str)

Calculates the metaphone key of str.

Similar to soundex() metaphone creates the same key for similar sounding words. It's more accurate than soundex() as it knows the basic rules of English pronunciation. The metaphone generated keys are of variable length.

Metaphone was developed by Lawrence Philips <lphilips@verity.com>. It is described in ["Practical Algorithms for Programmers", Binstock & Rex, Addison Wesley, 1995].

`A good reference to explain how the metaphone stuff works (and show you a working example) is: http://www.lanw.com/java/phonetic/`

`You can see this function at work at http://wamex.org. My only wish is that it returned phonetic values for numbers, instead of "".`
