It works. Your url will show as :::1
The code is:

"(via $ipaddress)" ; } else { $ipaddress = getenv('REMOTE_ADDR'); echo "Your IP address is : $ipaddress"; }I tried with the given php code “to determine or retrieve visitors ip address in PHP” in two different machines and got the same ip address.
I want to get visitor IP address into table of my database.
please help me
thanks
you can do it by simple code
just change host, user, password, dbname and table
first create a table and add two columns at least like ip_id and ipaddress.
then copy and paste the below code at last just change what you want.
code:
______________________________________________________
mysql_connect(“host”,”user”,”password”) or die(‘problem in conection’);
mysql_select_db(“dbname”) or die(‘problem in database’);
mysql_query(“INSERT INTO table_name (‘ipaddress’) VALUES (‘”.$ipaddress .”‘)”) or die(“error in querry”);
now you have ipaddress in your database table.

I think u get a Ip address from the DHCP server.
In This case You should the ip address of the Server and not of the client Machine.
Anyways this solved my problem….
Thanks a ton.

I am PHP web developer & CEO of web development company. I have excluded my office’s IP address from Google analytics.
But, I am little bit confuse with data of Google analytics which still give me details regarding my office staff member’s visit.
Can I make some integration to solve this issue? I want to check IP address of all visitors who are visiting my website in specific time frame.
Can you give me some idea about it or not? May I do it with help of Google analytics?
Hold on. You said it can get the IP address of someone using a proxy. NOT TRUE. I’ve just tested this on a variety of proxies, and it didn’t stop it. Totally useless extra line of code.
I am enhancing my website with php code I have the following code that will display a message to the suspect of an sql injection what I would like to do is add some code to log the visitors IP address to a table called sql_injection_suspects where it will store the IP address and the time of the event and the value of the save string:
$PUserid=strip_tags($_POST['lUSER']); $Ppassword=Strip_tags($_POST['lPASSWORD']); $sqlSafeUserid=mysqli_real_escape_string($con, $_POST['lUSER']); //Query users table and Email table to see if either exist $queryUserid = mysqli_query($con,"SELECT UserID, Password FROM tt_users WHERE UserID='$sqlSafeUserid'"); $rowUserid = mysqli_num_rows($queryUserid); if (strpos($sqlSafeUserid, '\\') !== false) { echo 'your attempt to inject sql into my database has been reported we have modified your input to: ' .$sqlSafeUserid .''; echo '\'s and "s are not permited in feilds that query databases and will be prefixed with a \\'; echo 'Click here to leave my website with your head hanging in shame'; } else {// Some code to find the userid and validate the userid and password }Hi every one my name is AlAa
My problem with $_SERVER[‘remote_addr’]
I’m not sure if I’m having a problem with the installation of PHP on the server or if there’s something that I’m not doing right in the code, but I am trying to capture the IP address of anyone that is trying to log into a secure part of a site. Regardless of my IP address, when I do:
Code:
echo $_SERVER[‘remote_addr’];
It returns ‘192.168.1.1’. This is the first time I’ve written code that is being used on a Windows Server, so I don’t know if that has anything to do with it.
I’ve run phpinfo(), and in the PHP Variables section, it shows “_SERVER[“REMOTE_ADDR”]” : 192.168.1.1. Does this mean that the php.ini file is setup wrong, or am I missing something?
i am running my own server on windows 7 iis7.5 with php as fastcgi and i am behind a router with a dynamic ip not static and i am using
http://www.no-ip.com/ that give me a link to my router and i am opening 80 port in my router forwarding it to my id address 192.168.1.5 and i have tested a php file that contains
tested it using tor network that give me ip out of my network to test that file always give me the same result 192.168.1.1 i am trying to get IP address of the visitor and i asked someone of my friends to use this form it sends the same ip
i hope someone tells me what i am doing wrong and the solution for this problem
Thanks in advance
