PHP Error was encountered

Severity: Notice

Filename: database/DB.php Line Number: 133

Common: line 148

$objects[$class] =& instantiate_class(new $name());
return $objects[$class];

DB: line 133

$DB =& instantiate_class(new $driver($params));

Answer 1

The & was used in PHP4 to create objects, this attribution construction became obsolete in PHP5. To solve the problem just remove it.

Change:

$objects[$class] =& instantiate_class(new $name());
return $objects[$class];

To:

$objects[$class] = instantiate_class(new $name());
return $objects[$class];

The same applies to $DB =& instantiate_class(new $driver($params));
