The Object Log module allows developers to store objects, arrays and other
variables to a log table so that they may be inspected later. Multiple stored
variables may be displayed side-by-side in the Object Log under admin/reports.

The usage is similar to Devel module's dpm() or kprint_r() functions, but
is particularly suited for debugging server-to-server requests, such as cron
runs and web services, or for requests from anonymous and other unprivileged

Other uses include where the use of dpm() slows down the rendering of a page
to the extent where it is unusable or where Krumo is not able to render an


When you reach a point in a code at which you would like to store a variable,
call the object_log() function...

object_log($label, $data);

...where $label is a string representing a name to give the object in the log,
and $data is the variable you wish to store. If there is already a stored object
with the same $label, that entry will be overwritten in the log.

If you want to inspect the same object over time, you could append a date
string or other identifier to the label to give distinct entries:

$label = 'object_label' . date('ymd_His')
object_log($label, $data);

Stored objects may be inspected by any user with the "access devel information"
permission by going to admin/reports/object_log. While inspecting an object,
a second object may be selected to display both objects side-by-side.


This module requires that the following modules are also enabled:
