Bug Type: DBM/DBA related
Description: faulty dbmfetch()
Actually, dba is not really a replacement for dbm. dba requires special libraries to
be installed in a PHP server install. If an ISP has chosen to not install those, then
dba does not work. Moreover, on Windows platforms there are huge issues with
installing dba libraries anyway. The PHP install comes up with:
Warning: no such handler: db2
I have changed db2 to all other kinds of handlers (including gdbm) and have installed
those also, in addition to uncommenting the php_dba.dll include line in php.ini.
Doesn't work.
Being deprecated is one thing, but not working is quite another. I would imagine
deprecating something implies it will no longer be found in a future version. But
shouldn't it work for now? The problem, as I said earlier, is that dbm is the natural
fallback when all an ISP/Webhosting platform offers is dbm. dba and other kinds of
databases require a custom setup.
Thanks,
Amir

Have you tried using the dba extension instead?
ie. change php_db.dll to php_dba.dll and check
the manual pages for dba extension how to use it:
http://www.php.net/dba
FYI: The db extension is deprecated.

sample code:
<?
$db = dbmopen("test007","n");
dbminsert($db,"key1","data1");
dbminsert($db,"key2","data3");
dbminsert($db,"key2","data2");
print "n<br> Value here should be data1: ";
print dbmfetch($db,"key1");
print "n<br> Value here should be data2: ";
print dbmfetch($db,"key2");
print "n<br> Value here should be data3: ";
print dbmfetch($db,"key3");
dbmclose($db);
?>
here is the bug description:
don't even try using this function in php4.x on windows. it is extremely buggy;
returns bad data. typically, you will find the first character of inserted data
missing, with some wierd chars at the end. on examining the dbm file, it seems the
php_dbm.dll methods are incorrectly reading data by skipping the first character,
reading the rest of the string and then getting completely messed up because all
following string length entries are "shifted".
i don't know how this huge bug has survived in all php 4.x implementations on windows.
it basically renders php 4.x on windows useless for disk based db access. i replaced
my 4.x install with 3.x and had no problem running my dbm code.
please somebody! fix this!
thanks,
amir
