metaphone — Calculate the metaphone key of a string

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 at verity dot com>. It is described in ["Practical Algorithms for Programmers", Binstock & Rex, Addison Wesley, ].

str

The input string.

This parameter restricts the returned metaphone key to phonemes characters in length. The default value of 0 means no restriction.
