[PHP-BUG] Bug #60123 [NEW]: Metaphone returns string longer than limit
From: Operating system: Windows XP SP3 PHP version: 5.3.8 Package: Unknown/Other Function Bug Type: Bug Bug description:Metaphone returns string longer than limit Description: The metaphone function accepts two parameters: an input string, and a string length limit. With certain input, it is possible to cause metaphone to return a string longer than the specified limit. The issue seems to arise when the string is nearing it's length limit and the following input character is an X, which can translate to a KS, pushing the string over its limit.

[PHP-BUG] Bug #60314 [NEW]: Metaphone returns fewer phonemes than defined
From:
Operating system: Windows XP SP3
PHP version: 5.3.8
Package: Unknown/Other Function
Bug Type: Bug
Bug description:Metaphone returns fewer phonemes than defined
Description:
Under certain conditions, the metaphone function returns fewer phonemes
than the $phonemes parameter specifies. This is an edge-case occurrence
when dealing with an X near the end of the specified phoneme count.
For the test script, the following phoneme transformations take place:
A -> A
X -> KS
C -> K
Test script:
---
KS" is one phoneme
var_dump('axccc', 0); // Should produce AKSKKK
?>
Expected result:
string(3) "AKS"
string(4) "AKSK"
string(6) "AKSKKK"
Actual result:
--
string(3) "AKS"
string(3) "AKS"
string(6) "AKSKKK"

New Comment:
This doesn't have anything to do with it "going over" the phoneme limit
parameter, it's about it translating too few phonemes.
If you're defining (X -> KS) as one phoneme, then metpahone('axc', 3) == 'AKS'
is incorrect because it only translated (A -> A) and (X -> KS) which is two
phonemes. Translating three phonemes - (A->A), (X->KS), (C->K) - should have
yielded 'AKSK'.
If you're defining each K and S from (X -> KS) as a phoneme, then
metaphone('axc', 2) == 'AKS' is incorrect as per bug #60123 (going over
restricted number of phoneme characters). If that isn't a bug, then the
documentation should be modified to note it as such.
Regardless, something is amiss here.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
It works following the Text-Metaphone CPAN package, it stop decoding when reach
the limit of phonems, but when decoding the last char it can pass the limit
suplied, because this metaphone('AX', 2) == metaphone('AXC', 3).
