Why was it necessary to have this in Zend Framework, what benefits does it add? Why not just use the normal php exceptions?

The class names of the exceptions can be used when you catch exceptions and you can handle different types of exceptions in different ways. Generally, each module in the zend framework has different exception classes.
For example, if you're using
Zend_Queue
, the library will returnZend_Queue_Exception
exceptions, which extendsZend_Exception
. It might also returnZend_Db_Exception
exceptions if the exception is related to the queue database adapter.$options = array( 'name' => 'queue', 'driverOptions' => $options ); try { $queue = new Zend_Queue($config->queue->adapter, $options); } catch (Zend_Queue_Exception $e) { // handle queue issues } catch (Zend_Db_Exception $e) { // handle db issues }
