I'm looking through various documentation on MDB2
In some examples the assignment operator looks like it is mixed with a
bitwise or logic operator - IE
$mdb2 =& MDB2::factory($dsn);
Other examples though just have
$mdb2 = MDB2::factory($dsn);
I'm trying to figure out exactly what =& does, why people would use it,
and when it is appropriate to use, but I haven't found anything and I
think my google skills need some practice as I don't know how to search
for =& in google.
In the php manual on operators I did fine &= discussed but that's the
flip and it's use makes no sense in the context of setting a database
handle.
Any tips would be appreciated.
