flags
Optional flags to add additional information to the profiling. See the
XHprof constants for further
information about these flags, e.g., XHPROF_FLAGS_MEMORY
to enable memory profiling.
optionsAn array of optional options, namely, the 'ignored_functions' option to pass in functions to be ignored during profiling.
