Yes. The reason was that PHP currently does not support a pure
ActiveRecord implementation due to lack of late static binding (LSB --
which will be available in PHP 5.3.0).
What that essentially meant was that we could not do the following:
$bug = Bug::find(3);
simply by declaring the following:
class Bug extends Zend_ActiveRecord
{
}
due to the fact that 'self' always refers to the defining class, not the
class from which it was called.
ZF implements the Table Data Gateway and Row Data Gateway via
Zend_Db_Table and Zend_Db_Table_Row. These are incredibly flexible, and
do not require the use of static methods -- which allows them to bypass
LSB and simply work. RDGs are very similar to ActiveRecord in use.
