    $userAccNames = $userRow['account_name'];

    $userAccNames = explode(',', str_replace(['{', '}', '"'], "", $userAccNames));

    $mgrAccNames  = explode(',', str_replace(['{', '}', '"'], "", $mgrAccNames));

    $accounts     = array_intersect($userAccNames, $mgrAccNames);

    if (!empty($accounts)) {

        $tableStr .= "<tr>";

        $tableStr .= "<td><select name='selectAccounts' id='selectAccounts'>";

        foreach ($accounts as $account) {

            $tableStr .= "<option>{$account}</option>";

        }

        $tableStr .= "</select></td>";
