php - compare two multidimensional arrays of object and set new property true/false pending match on larger set -

-

i have array of objects example:

larger set:

array(     [0] stdclass object(                         [id] => 1,                         [name] => monkey,                         [sub] =>                        ),     [1] stdclass object(                         [id] => 1,                         [name] => tooth,                         [sub] => tip                        ),     [2] stdclass object(                         [id] => 1,                         [name] => who,                         [sub] => knows                        ),     )

smaller set

array(     [0] stdclass object(                         [id] => 1,                         [name] => monkey,                         [sub] =>     )

desired out come:

array(     [0] stdclass object(                         [id] => 1,                         [name] => monkey,                         [sub] => help,                         [selected] => yes                        ),     [1] stdclass object(                         [id] => 1,                         [name] => tooth,                         [sub] => tip,                         [selected] => no                        ),     [2] stdclass object(                         [id] => 1,                         [name] => who,                         [sub] => knows,                         [selected] => no                        ),     )

so know above horrible example sake of example, , keeping post being mile long bare me. trying play doesn't seem working is

    foreach($result_static $stock)     {         foreach($result_memb $memb_choice)         {             $stock->selected = "false";             //echo $stock->name .' == '. $memb_choice->name.'<br>';             if($stock->name == $memb_choice->name)             {                 $stock->selected = "yes";             }         }         $output[] = $stock;     }

this doesn't appear matching of actual results, , gather foreach logic off cause either due relooping second loop many times or first 1 withing other way, names each never match respectively way hope.. trying ideas on how better tackle this, , bit more optimized nice, ill take can currently.

try 

foreach($result_static $stock)     {         $stock->selected = "false";         foreach($result_memb $memb_choice)         {             if($stock->name == $memb_choice->name)             {                 $stock->selected = "yes";             }         }         $output[] = $stock;     }
