无法在数据库中获取正确的 IP 地址

Question

I have the below simple code for inserting some failed login values in my database, but I have some problems:

1- The ip address is being saved in the database as zero no success whatever I do (going crazy on this). 2- I used current time stamp to get the date and time in a simple query, now that I use prepared statements it doesnt work with it, I am forced to use date('Ymd H:i:s'); which gives out the wrong time.

My code is:

<?php
    $username = $_SESSION['Name'];
    $ip_address = $_SERVER['REMOTE_ADDR'];
    $attempted = date('Y-m-d H:i:s');
    $query = "INSERT INTO failed_logins (username, ip_address, attempted) VALUES(?, ?, ?)"; 
    $failed = $conn->prepare($query);
    $failed->bindParam(1, $username);
    $failed->bindParam(2, $ip_address);
    $failed->bindParam(3, $attempted);
    $failed->execute();
?>

My ip_address row in the database is int(11) and it is unsigned.

Any suggestions would help thanks

UPDATE:

I did the below but still no luck:

I changed:

 $ip_address = $_SERVER['REMOTE_ADDR']; 

to this:

 $ip_address = ip2long($_SERVER['REMOTE_ADDR']);

Have you tried setting the date_default_timezone_set , ie:

date_default_timezone_set('America/Los_Angeles');

You cannot use an int to store a var containing dots ans colons . Change the DB ip_address row from

int(11)

to

varchar(15); //ipv4

#

ALTER TABLE `sometable`
MODIFY COLUMN `ip_address` varchar(15);

Or

varchar(45); //ipv6

#

ALTER TABLE `sometable`
MODIFY COLUMN `ip_address` varchar(45);

if you want to store ipv6 addresses

Maximum length of the textual representation of an IPv6 address?

Also maybe to get IP(ish):

(string)$ip_address = getRealIpAddr();

function getRealIpAddr() {
    (string)$ip='';
    if (array_key_exists('HTTP_CLIENT_IP', $_SERVER) && !empty($_SERVER['HTTP_CLIENT_IP'])) {   //check ip from share internet
      $ip .= filter_input(INPUT_SERVER, 'HTTP_CLIENT_IP');
    } elseif (array_key_exists('HTTP_X_FORWARDED_FOR', $_SERVER) && !empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {   //to check ip is pass from proxy
      $ip .= filter_input(INPUT_SERVER, 'HTTP_X_FORWARDED_FOR');
    } else {
      $ip .= filter_input(INPUT_SERVER, 'REMOTE_ADDR');
    }
    return $ip;
}
