function_profile(3)

NAME
function_profile() - get function profiling information for an object

SYNOPSIS
mixed *function_profile(object ob);

DESCRIPTION
Returns function profiling information for `ob', or this_object() if `ob' is not specified. This is only available if the driver was compiled with PROFILE_FUNCTIONS defined.

RETURN VALUE
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,
          "self" : cpu_time_spent_in self, /* in microseconds */
          "children" : cpu_time_spent_in_children /* in microseconds */
       ])

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
