#16809 — how extract key and valu from object

with print_r ($opzioni_select);
I have this:
Array (
[all] => Select
   [0] => stdClass Object ([option] => Array ([29] => A))
   [1] => stdClass Object ([option] => Array ([28] => B ))
   [2] => stdClass Object ([option] => Array ([31] => C ))
)


after with
foreach ($opzioni_select as $key)
{
print_r ($key->option);     echo '<br>';

}

heve this:
Array ([29] => A)
Array ([28] => B)
Array ([31] => C)


I would like to create a new array
$newArr[ array_keys($key->option) ] = array_values($key->option);
but have this error: The first argument should be an array

how can get for every element the key and the value?

An array where I can to extract for every elements the key and the value

var_dump gives you more detailed information.

And a notice that you are "Trying to get property of non-object".  If
you don't see this you should probably turn notices on since they can
help a lot.

You need to avoid accessing $key->option when the $key is 'all'.

It's possible that you want

  $newarray[array_keys($obj->option)[0]] = array_values($obj->option)[0];

but, if not, please give the actual values you'd like to see in
$newarray.  Also note that you will have to deal with the 'all' case as
I mentioned above.

This bit I don't follow.  You can do that for every array.

thanks for you suggestion I must see with calm

I find this solution also if isn't short
seen that
  print_r ($op_select);
I have this structure
Array (
[all] => Select
    [0] => stdClass Object ([option] => Array ([29] => A))
    [1] => stdClass Object ([option] => Array ([28] => B ))
    [2] => stdClass Object ([option] => Array ([31] => C ))
)



I solved so
$new = array();
  $i=0;
foreach ($op_select as $key) {
$i++;
if ($i==1)
{
   $new['all'] = $key ;
}
else
{foreach ( $key->option as $key1 => $val1)
              {echo $key1.' '.$val1.'<br/>';
               $newArr[ $key1 ] = $val1;}

}
}

only for first key
I set manually the key All and assign value Select by $key
this is a cicle also if inner variable I have only on element

after I take key and value by
Array ([29] => A)
Array ([28] => B
Array ([31] => C
with foreach ( $key->option as $key1 => $val1)
but think this isn't the better solution
but work;
