function_profile() - get function profiling information for an object
mixed *function_profile( object ob );
Returns function profiling information for 'ob', or this_object() if 'ob' is not specified. This is only available if the driver was com‐ piled with PROFILE_FUNCTIONS defined.
An array of mappings is returned, one for each function in 'ob', the format of the mapping is: ([ "name" : name_of_the_function, "calls" : number_of_calls, /* cpu time expressed in microseconds */ "self" : cpu_time_spent_in self, "children" : cpu_time_spent_in_children ]) The usefulness of this is tied to the resolution of the CPU clock--even though the units are microseconds, the CPU timer resolution is often much less
