PHP :: Bug #3371 :: dbmfetch reurns an empty string

[2000-02-01 06:54 UTC] kredel at rz dot uni-mannheim dot de

A counter function written in php and using gdbm is no more
working. the dbmfetch funktion returns empty string, while
dbmexists indicates the existence of an string. looking 
into the dbm file shows the value is there. I include first
the output of two different systems (the first is th buggy one) and then the php script.
