I'm using PHP 4.2.2 for Windows with Apache 1.3.24.
I have loaded php_db.dll for DBM support.
When writing to a DBM database and re-reading data, I get different from that I inserted. Here is a script to reproduce the problem:
[please delete "db" & "db.lck" if exists]

<? $dbm=dbmopen("db","c") or die("DBM error");
dbmreplace($dbm,"7","alpha");
echo dbmfetch($dbm,"7");
dbmclose($dbm); ?>

The program output is "lpha" (w/o quotes). The starting "a" seems to be cut. When analyzing the "db" file, it contains the whole string (31 0A 37 35 0A 61 6C 70 68 61 00).

I'm not completely sure if it is a php bug, I'm also interested whether you can reproduce the error or not.

(1) Seems to be very similar to bugreport 16190
(2) Truncation looks dependent on key string length

Sorry, this appeared fixed on first testing but actually isn't.  Keeping this one closed against the duplicate (re-opened) bug #16190.
