提问by user3680002
I am doing this following code for login attempt & i want get IP address of my local machine..
我正在执行以下登录尝试代码，我想获取本地计算机的 IP 地址。
if ( !$this->session->userdata('login_attempts') )
{
$this->session->set_userdata('login_attempts', 0);
}
$attempts = ($this->session->userdata('login_attempts') + 1);
$this->session->set_userdata('login_attempts', $attempts);
// Check if the session.
if ( $this->session->userdata('login_attempts') > 4 )
{
echo 'hi....login attempt is over';
}
// Failed. So, update the session
echo $ip = $_SERVER['REMOTE_ADDR'];
// $ip_address = $this->input->ip_address1();
// return $ip_address;
echo $this->input->ip_address();
if ( ! $this->input->valid_ip($ip))
{
echo 'Not Valid';
}
else
{
echo 'Valid';
}
$this->db->update('loginattempts',array( 'login_attempts' =>$this->session->userdata('login_attempts') , 'lastLogin' =>date('Y-m-d H:i:s'),'ip'=>$ip = $_SERVER['REMOTE_ADDR'] ),array('login_id' =>1) );
echo ('hi....login attempt is'.$this->session->userdata('login_attempts'));
}
but it show incorrect ip address of my local machine.
但它显示了我本地机器的错误 IP 地址。

Use $this->input->ip_address();
用 $this->input->ip_address();
Codeigniter Input User Guide (ip_address)
Codeigniter 输入用户指南 (ip_address)
Also, don't echo an equation. echo on another line instead:
另外，不要重复方程。在另一行回显：
$ip = $this->input->ip_address();
echo $ip;

To get the remote IP address, in PHP, you could use $_SERVER['REMOTE_ADDR'], CodeIgniter is doing the same thing behind the scenes.
要获取远程 IP 地址，在 PHP 中，您可以使用$_SERVER['REMOTE_ADDR']，CodeIgniter 在幕后做同样的事情。

Controller
控制器
$data['ip'] = $this->input->ip_address();
view
看法
<?= $ip ;?>
回答by BALAJI R
use anyone from below .. same like $_SERVER['REMOTE_ADDR']
使用下面的任何人.. 与 $_SERVER['REMOTE_ADDR'] 一样
$_SERVER['HTTP_X_FORWARDED_FOR']
$_SERVER['HTTP_CF_CONNECTING_IP']
We should use codeigniter function for security,
we should use $this->input->ip_address();, This will give client ip
我们应该使用 codeigniter 函数来保证安全，我们应该使用$this->input->ip_address();, 这会给客户端 ip
If you want to access server variable use like this
如果要访问服务器变量，请像这样使用
$this->input->server(array('HTTP_CF_CONNECTING_IP', 'HTTP_X_FORWARDED_FOR')));
