Description:
------------
When I run metaphone('scratch'), I get string(5) "SKRTX"

This is wrong. According to the rules posted for metaphone, T before CH is silent, so the result should be "SKRX". My Javascript metaphone function gets this right and I need the two to match up!

Reproduce code:
---------------
<?php 
  echo metaphone("scratch");
?>

Expected result:
----------------
SKRX

Actual result:
--------------
SKRTX

Exactly what algorithm does your JS func use?

Thank you for the report, and for helping us make PHP better.

You are right according to Lawrence Philips' Metaphone Algorithm.

Fixed in 5.3 and HEAD.

Thanks.
