Implode all the properties of a given name in an array of object - PHP [duplicate]

Answer 1

I usually make a Helper for this situation, and use it like this

function GetProperties(array $arrOfObjects, $objectName) {
     $arrProperties = array();
     foreach ($arrOfObjects as $obj) {
         if ($obj->$objectName) {
              $arrProperties[] = $obj->$objectName;
         }
     }
     return $arrProperties;
}
