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. 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, ].
参数str
The input string.
phonemes
This parameter restricts the returned metaphone key to phonemes characters in length. The default value of 0 means no restriction.
返回值Returns the metaphone key as a string, 或者在失败时返回 FALSE.
范例

<?phpvar_dump(metaphone('programming'));var_dump(metaphone('programmer'));?>以上例程的输出类似于：
Example #2 Using the phonemes parameter
<?phpvar_dump(metaphone('programming',5));var_dump(metaphone('programmer',5));?>以上例程的输出类似于：
