Description
string metaphone
( string $str
[, int $phones
] )
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,
1995].
