metaphone — Calculate the metaphone key of a string
Description
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, 1995].
Parameters
-
str -
The input string.
-
phonemes -
This parameter restricts the returned metaphone key to
phonemescharacters in length. The default value of 0 means no restriction.
Return Values
Returns the metaphone key as a string, or FALSE on failure.
Examples
Example #1 metaphone() basic example
<?php
var_dump(metaphone('programming'));
var_dump(metaphone('programmer'));
?> The above example will output something similar to:
string(7) "PRKRMNK" string(6) "PRKRMR"
Example #2 Using the phonemes parameter
<?php
var_dump(metaphone('programming', 5));
var_dump(metaphone('programmer', 5));
?> The above example will output something similar to:
string(5) "PRKRM" string(5) "PRKRM"
