使用数组元素更新Postgres表

我想用数组元素更新Postgres数据库表，但我不知道如何。

我试过了，但我得到了这个通知:注意:未定义的索引:'值'在'文件'行x

更新:

private function debug ($function_name, $arg_names, $arg_vals (<=with func_get_args())  ) 
{
    $arg_names_array = explode(',', $arg_names);
    foreach($arg_names_array as $k => $v)
    {
        $v = trim($v);
        $v = pg_escape_string($v);
        $vars[$k] = $arg_vals[$v];
    }
    $this->return_ = $vars;
    return $this->return_;  
}
pg_query($connect, "UPDATE tabe SET row = {$vars[$first]}  WHERE code = {$vars[$code]} ");
pg_query($connect, "UPDATE tabe SET row = '{$vars[$first]}'  WHERE code = '{$vars[$code]}' ");
