Editor's Notes
- #2 test
- #19 http://symfony.com/doc/current/book/performance.html#use-a-byte-code-cache-e-g-apc
- #22 autoload class dosyalarının filecheck ile path kontrollerinin önün geçer
- #25 Object relational mapper (ORM) for PHP that sits on top of a powerful database abstraction layer (DBAL). One of its key features is the option to write database queries in a proprietary object oriented SQL dialect called Doctrine Query Language (DQL), inspired by Hibernates HQL. This provides developers with a powerful alternative to SQL that maintains flexibility without requiring unnecessary code duplication.
- #31 Something to be careful of when using the cache drivers is “cache slams”. Imagine you have a heavily trafficked website with some code that checks for the existence of a cache record and if it does not exist it generates the information and saves it to the cache. Now, if 100 requests were issued all at the same time and each one sees the cache does not exist and they all try to insert the same cache entry it could lock up APC, Xcache, etc. and cause problems. Ways exist to work around this, like pre-populating your cache and not letting your users’ requests populate the cache.
- #33 In many cases associations between entities can get pretty large. Even in a simple scenario like a blog. where posts can be commented, you always have to assume that a post draws hundreds of comments. In Doctrine 2.0 if you accessed an association it would always get loaded completely into memory. This can lead to pretty serious performance problems, if your associations contain several hundreds or thousands of entities. With Doctrine 2.1 a feature called Extra Lazy is introduced for associations. Associations are marked as Lazy by default, which means the whole collection object for an association is populated the first time its accessed. If you mark an association as extra lazy the following methods on collections can be called without triggering a full load of the collection: Collection#contains($entity) Collection#containsKey($key) (available with Doctrine 2.5) Collection#count() Collection#get($key) (available with Doctrine 2.4) Collection#slice($offset, $length = null)
- #35 Another interesting use-case: updating an object without loading it (as an alternative to a DQL bulk UPDATE): $user = $em->getPartialReference('User', $userId); $user->setName('newname'); $em->flush();
