PHP Bug Type: Unknown/Other Function
Bug description: metaphone and 'wh'
Description:
------------
The source for metaphone() states in the comments that "WH becomes H" and
when one tests it, e.g., with "whit", as per the comment on line 227 and
the code which phonizes Next_Letter on line 233 when there is a 'W'
followed by 'H', it returns 'H' ("ht" for 'whit').
However, according to the metaphone() algorithm (see
http://aspell.net/metaphone/ and the original implementation at
http://aspell.net/metaphone/metaphone.basic ), 'wh' should become 'w', not
'h'.
So, to fix it, you could change the comment on 233 to:
/* WH becomes W,
and then change the 'if' on 231-234 to:
if (Next_Letter == 'H') {
Phonize('W');
w_idx += 2;
} else if (Next_Letter == 'R') {
Phonize(Next_Letter);
w_idx += 2;
Reproduce code:
---------------
<?php
echo metaphone('Whit');
?>
Expected result:
----------------
WT
Actual result:
--------------
HT
