如何使用PDO插入然后在同一函数中返回`lastInsertId（）`？

Question

How can you insert with PDO then return the lastInsertId() that was created? This can be done inside the function, but I either way I would like to get the lastInsertId() outside the function.

function insert_PDO($item1, $item2){

        $params =   array(
                        ":item1"        =>      $item1 ,
                        ":item2"        =>      $item2 
                    );

         $sql = "INSERT INTO table                  (column1,   column2)
                VALUES                              (:item1,    :item2)
            ";

    //return $this->insert($sql, $params);    //this one works

    //now trying this, want to return 

            $insertitems    = $this->insert($sql, $params);  
            $item_ID        = $this->lastInsertId();  
            return ($insertitems, $item_ID) ;  //does not work
}

protected function insert($sql, $params)
{
    $stmt = $this->dbh->prepare($sql);
    return $stmt->execute($params);
}

// I tried this too with the original insert:

    $results        =       $createInsert   ->  insert_PDO($item1, $item2);
    $lastid = $results[0];

    foreach($results1 as $row){
        $auditVID = $row[ID];
        $auditVID = $row[0];
    }

Statement

return ($insertitems, $item_ID) ; 

will cause syntax error.

If you want to return several values - use array:

$insertitems    = $this->insert($sql, $params);  
$item_ID        = $this->lastInsertId();  
return array($insertitems, $item_ID) ;
// or for newer php versions:
return [$insertitems, $item_ID];
