Re: [Phpwiki-talk] lib/DbSession/SQL.php:97: Notice: Only variables should be assigned by reference

Line 97 looks like this:

      $dbh = &$this->_connect();

The reference is created by the ampersand. For the moment, it's unclear to
me what purpose the reference here is serving. Hence my question for Reini:


Reini: I noticed that in the DbSession code that the db handles are acquired
from _connect() using a mix of references and straight assignment (SQL.php
and ADODB.php use references only, dba.php uses assignment only, and PDO.php
uses a mix of the two). Is there a reason why these aren't uniform? I.e.,
do any of them actually need to be references? (I don't think so, but I
could be wrong.)
