I know we can use the user method of ion auth to get user data.
$user = $this->ion_auth->user()->row();
echo $user->ip_address;
But this gives an output u�8/ .How can I retrieve the actual ip address like 127.0.0.1.
UPDATE
Just to help others.
With help from h2ooooooo,I found that ipaddress is passed through bin2hex(inet_pton($ip)) and then saved in db. To retrieve it use
$user = $this->ion_auth->user()->row();
echo inet_ntop($user->ip_address);
您确定 IP 是使用存储的inet_pton吗？
如果我们简单地将每 2 个字符转换为十进制，结果如下：
<?php
$ipPacked = '75f1382f';
$ipSegments = array();
for ($i = 0; $i < 8; $i += 2) {
$ipSegments[] = hexdec($ipPacked[$i] . $ipPacked[$i + 1]);
}
$ipReal = implode('.', $ipSegments);
var_dump($ipReal); //string(13) "117.241.56.47"
?>
那是你正确的IP吗？
如果是 inet_pton（这没有意义，因为其中大多数是常规 ASCII 范围之外的字符），那么您可以简单地使用inet_ntop它来取回它。
要将 IP 转换为这种十六进制格式，您可以执行以下操作：
<?php
$ip = '117.241.56.47';
$ipSegments = explode('.', $ip);
$ipPacked = '';
for ($i = 0; $i < 4; $i++) {
$ipPacked .= sprintf("%02s", dechex((int)$ipSegments[$i]));
}
echo $ipPacked; //75f1382f
?>
