Thank you for asking questions, StackOverflow found the answer, the following translation here:
1. When returning a specific data type, use Stdclass, such as:

$person   -> name = "John"   -> surname = "Miller"   -> address = "123 Fake St"

2. Use an array when returning a list of the same type of data, such as:

  "John Miller"  "Peter Miller"  "Josh Swanson"  "Harry Miller"

3. When returning a specific type of list, use StdClass, array, such as:

 $person[0]    -> name = "John"    -> surname = "Miller"    -> address = "123 Fake St"  $person[1]    -> name = "Peter"    -> surname = "Miller"    -> address = "345 High St"

Personal opinion: It is more convenient to use array or stdclass for different purposes, or combine them.

I used to save the data mainly is the cost is relatively small

$obj = new stdClass;$obj->test = 'abc';$obj->other = 6.2;$obj->arr = array (1, 2, 3);

More convenient than arrays

Test

$size = 200000;mark (), $SC = new Stdclass;foreach (range (1,5) as $i) {$SC $i = Pow ($i, 2);}    Mark ();d UMP (' SC ', 1), Mark (), foreach (Range (1, $size) as $i) {$SCN = "sc". $i;    $ $scn = $SC; $arr _sc[] = $SC;} Mark ();d UMP (' SC '), Mark (), $arr =[];foreach (range (1,5) as $i) {$arr [] = Pow ($i, 2);}    Mark ();d UMP (' arr ', 1), Mark (), foreach (Range (1, $size) as $i) {$arrn = "arr". $i;    $ $arrn = $arr; $arr _arr[] = $arr;}    Mark ();d UMP (' arr '); function dump ($var, $size = 200000) {Global $mem _size, $times, $ $var;    Xdebug_debug_zval ($var); echo "Total:". Round (($mem _size[count ($mem _size) -1]-$mem _size[count ($mem _size)-2])/pow (1024,2), 3). " Mb "." AVG: ". Round (($mem _size[count ($mem _size) -1]-$mem _size[count ($mem _size)-2])/(1024* $size), 3). "Kb". " Time: ". Round (($times [Count ($times)-1]-$times [Count ($times)-2]), 3). " \ n ";}    function mark ($type =0) {global $mem _size, $times;    $mem _size[] = Memory_get_usage (); $times [] = Microtime (true);}

Results

TOTAL:0.002MB avg:1.773kb time:0
TOTAL:18.785MB avg:0.096kb time:0.101
TOTAL:0.001MB avg:1.227kb time:0

In Orm, each record of a query is converted into a class, and each field becomes a property
