 PHP Profiler lets you pass in some configuration options to help allow it to suit your own needs.
 
 - **query_explain_callback** is the callback used to explain SQL queries to get additional information on them. The format used should be the same as that used by PHP's [call_user_func](http://us2.php.net/call_user_func) function.
+- **query_profiler_callback** is used to integrate an extended query profiler such as [MySQL's query profiler](http://wiki.github.com/steves/PHP-Profiler/the-extended-query-profiler).
