Patch for PHP maxdb_fetch_array($result, MAXDB_ASSOC_LOWER)

Question

I've just discovered a bug in the PHP module for MaxDB.
Using maxdb_fetch_array() with resulttype MAXDB_ASSOC_LOWER or MAXDB_ASSOC_UPPER results in a wrong array. In fact there are two bugs.
1) With MAXDB_ASSOC_LOWER, the array index is only converted to lowercase for certain data types. Example:
["groupid"]=>  string(1)
["AMOUNT"]=>  float(0.05)
["currency"]=>  string(3) "CHF"
The field "AMOUNT" has not been converted to lowercase.
2) With MAXDB_ASSOC_LOWER or MAXDB_ASSOC_UPPER, the array is missing all elements with NULL value. Example with MAXDB_ASSOC_UPPER:
["GROUPID"]=>  string(1)
["AMOUNT"]=>  float(0.05)
["CURRENCY"]=>  string(3) "CHF"
The patched PHP module results in the correct array, like this:
["groupid"]=>  string(1)
["invoice_pos"]=>  NULL
["amount"]=>  float(0.05)
["currency"]=>  string(3) "CHF"
This patch fixes it for me [maxdb-7.6.00.38-php_assoc.patch|http://www.invoca.ch/pub/maxdb-7.6.00.38-php_assoc.patch]

Hi Alex,
Unfortunately I don't have an idea what is wrong in your case. But what I know is that I also found bugs in the php maxdb extension and it may well be that you have found a bug too. Maybe it's just a question of different types of float, maybe the types you use does not map between maxdb and php. Just a wild guess because I'm far from being en expert on this.
I have put the patches I'm using in my rpms here [PHP MaxDB patches|http://www.invoca.ch/pub/packages/maxdb/] they are from the bugtracker at pecl.php.net and maxdb-7.6.00.38-php_assoc.patch is the one I created after I found a bug.
I don't really think one of those patches will help in your case but you may want to try it anyways.
BTW, the link will only be valid today.
