Raw output snippet with, XHPROF_FLAGS_CPU + XHPROF_FLAGS_MEMORY.[main()] => Array(    [ct] => 1                // number of calls.    [wt] => 419              // wall/wait time (ms).    [cpu] => 0               // cpu time.    [mu] => 8264             // memory usage (bytes).    [pmu] => 0               // peak memory usage.)
