Use array_map in order to get an array of usernames like so:

array_map(function($row) {
    echo $row['username'];
}, $object->rows);

// $usernames = ['Papino', 'Sophia', ..]

Thanks, but this doesn't work, PHP reports Parse error for unexpected ')', however this is not I am cared about. I think there must a way to echo the values that held in my $result variable which is a stdClass object as I mentioned above, by using the foreach or while loop, I just don't know how to do it.

I put an extra ) my answer is updated, if you only want to print the usernames change the return for echo

Try the following snippet change $object with your StdClass Object Name.

$userNames = [];
foreach($object->rows as $item){
  $userNames []  = $item['username'];
}

var_dump($userNames);

update after comments There is no way to do it with var_dump solely, you should some jobs to get it.

in my projects I always use Krumo instead of print_r , var_dump

$userNames = [];
foreach($object->rows as $item){
  echo  $item['username'].PHP_EOL;
}

Thanks for your quick answer, but I don't want to var_dump the $userNames, I already have those values saved in my variable like $result for example. If I var_dump my $result I got above data structure which is a stdClass includes a 2 dimensional array, all I want is echo/print out all of the inner-most values like Justin,Papino,Sophia...NOT var_dump again!!!! hope I explained this well.

he answer is missing a ' in $item['username]; but if you just need to echo them out, the replace that line with echo $item['username'].PHP_EOL; or something similar.

@NigelRen thanks for your comment, I updated missing '.

This answer will basically work, just change this line $userNames [] = $item['username']; to echo $item['username']."<br>\n"; and then delete the var_dump line.

Thanks, I simply used foreach($result->rows as $item){ echo $item['username']; } which did the perfect job.
