PHP optimizers and The Bug Genie – revisited

with one comment

As we are seeing more issues with php optimizers interfering with the core functionality of The Bug Genie, we’d like to post a little clarification.

First of all, we do not have an issue with optimizers. They exist for a reason, and we will do our best to not have our code break when optimizers are used – for whatever reason issues may occur ( phpinfo() can confirm if you are using an optimizer – look for “eaccellerator” or “optimizer”).

However – and this is important – not all optimization techniques are valid, and not all optimization techniques are non-intrusive. One of the techniques used by php optimizers (e.g. eaccellerator) is to remove php docblocks before the php compilation step. This optimization “feature” is highly controversial, and it is intruding on a core php feature – php docblocks are a part of the php language. Removing php docblocks will cause applications to malfunction.

There are several php projects other than The Bug Genie already relying on this php language feature (the ability to read php docblocks at runtime):

  • Doctrine 2
  • Zend Framework
  • PHPUnit

To read more about this “optimization” technique controversy, I recommend having a look at these two links:

The last blog post also contains information on how to disable this particular eaccellerator “feature” for certain files, and how to disable eaccellerator php docblock removal completely.

Unfortunately, we cannot do anything about this issue, as it is out of our control.
