metaphone
(PHP 4, PHP 5)
metaphone — Calculate the metaphone key of a string
说明
string metaphone
( string $str
[, int $phonemes = 0
] )
Calculates the metaphone key of str.
Similar to soundex() metaphone creates the same key for
similar sounding words. Its more accurate than
soundex() as it knows the basic rules of English
pronunciation. The metaphone generated keys are of variable length.
