Update, it turns out it's not the settype(). Here's a larger context of the
offending
area of code:
$query = '<my query>';
$queryResult =& $DBAccess->db->query( $query );
if( !( DB::isError( $queryResult ))) {
$tmpArray = array();
while( $queryResult->fetchInto( $tmpArray )) {
$dbObject = new IPI_OfficeDetailsInterface();
$dbObject->_populateMemberVariables( $tmpArray );
$retval[] = $dbObject;
$tmpArray = array();
settype( $dbObject, "null" );
}
}
The line to concentrate on is this one:
$dbObject = new IPI_OfficeDetailsInterface();
If I leave it as above, no error occurs. But I instead instantiate
$dbObject
as follows (which is what I was doing originally)
$dbObject &= new IPI_OfficeDetailsInterface();
then the error shows up in the log again. The error only goes away if I
either
remove the settype() function call or I remove the '&' in the instantiation.
Why?
thnx,
Chris
