How to detect how many times a certain method in PHP is called in one request, and the time and memory consumption each time?

function  microtime_float ()
{
    list( $usec ,  $sec ) =  explode ( " " ,  microtime ());
    return ((float) $usec  + (float) $sec );
}

  function test(){
     static $num = 0;
     $num ++;
     $memory =  memory_get_usage () ;
     $time_start  =  microtime_float ();
     // 操作过程略
     usleep ( 100 );
     $m = memory_get_usage () -$memory;//内存
     $t =  microtime_float () -$time_start;//耗时
     return [$num,$m,$t];
}
test();
test();
print_r(test());
Array
(
    [0] => 3
    [1] => 0
    [2] => 0.00016498565673828
)

Maybe you need this

Configure xdebug + kcachegrind and it will be fine.
