在这里，我试图将用户详细信息插入到 replit 数据库中。它已插入，但仅存储一个用户详细信息。例如，第一个我输入为 name=>test、email=>test@gmail.com、phone=>12121。此输入将插入数据库。但是第二次如果我输入其他用户详细信息，它将替换这个值。您能帮我将多个用户详细信息插入数据库吗？这里是 setKey() 函数。

 public function setKey($keyname, $data) {
    if ((isset($keyname)) && (!empty($keyname)) && (isset($data)) && (!empty($data))){

    // serialize the data so that it's in one key
    // if you do an array, it will make a key for each value
    $data = array($keyname => serialize($data));

    $options = array(
        'http' => array(
            'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
            'method'  => 'POST',
            'content' => http_build_query($data)
        )
    );
    $context  = stream_context_create($options);
    $result = file_get_contents($this->REPL_DB_URL(), false, $context);
    if ($result === FALSE) {
      return false;
    } else {
      return true;
    }
    } else {
      return "You must set a keyname and have data. Syntax: setKey($keyname, $data)";
    }
  }
