Provides a handy object inspection method for Magento developers.



To be honest, I had forgotten there is any other method besides info() in Emzee_Dev. I guess that most of the other functionalities is covered by FireGento_Debug and others now. I'll list them here for the sake of completeness.


The most useful function is info(). You can call it using the model or the helper:

# using a singleton model
echo Mage::getSingleton('emzee_dev/debug')->info($variable);

# using a helper
echo Mage::helper('emzee_dev')->info($variable);

info() is intended to be used with objects. Providing info() with other types will get you a simple print_r() output.

For objects, you get

  • A graphical presentation of the public methods that exits in the class and its parent classes.
    • You can see which class defines the method.
    • Hover over the method name to see the defining class.
    • Click on the method name to see the method declaration (variables, default values).
  • The names of the parent and child blocks if the object is a block class.
  • A nice backtrace showing the content of the files next to the called line.

Here is a screenshot so you get a better picture:

Emzee_Dev info() call


  • Prints the absolute pathes of various Magento folders.
  • Prints a list of all modules with status, code pool, dependencies and version.


Returns current memory usage in human readable format.


Returns information on models:

  • which model groups are defined in config XML files (node global > models)
  • what does that model group get translated to (e.g. "admin" => "Mage_Admin_Model")
  • if it is a "normal" model: what is the resource model for this model
  • if it is a resource model: which entities do exist for this model


  • Magento CE 1.7 - 1.9 (only tested here; initial version worked with 1.3 CE, so you may try it with older versions)
