This modification is important to note in ZF 1.9.3:
http://framework.zend.com/issues/browse/ZF-5606
The change will probably break some (older) applications.
Correct:
$db = Zend_Db::factory('Pdo_Mysql', $params);
Incorrect (as of ZF 1.9.3)
$db = Zend_Db::factory('PDO_MYSQL', $params);
There are many examples online and in books that use 'PDO_MYSQL'
instead of 'Pdo_Mysql'.
This issue effects applications on file systems that are case-sensitive.
You can check your code with the following:
find -name "*.php" | xargs grep -H "PDO_MYSQL" 2> /dev/null
This shows all occurrences of 'PDO_MYSQL' in all .php files.
Hope this helps someone!
