PHP has in built facility to detect remote browser or IP address and other properties. These values are assigned to special variable. In this case, it is assigned to variable called REMOTE_ADDR. You can use any one of the following statement to obtained or read IP address:
$ip = $_SERVER['REMOTE_ADDR'];
OR
$ip= $REMOTE_ADDR;
Here is sample code:
<?
$ip= $REMOTE_ADDR;
echo "<br> Your IP address : " . $ip;
echo "<br> Your hostname : " . GetHostByName($ip);
?>
See PHP getenv for more information.

Try the gethostbyaddr for this task.
How to get the remote IP location?
<?php
$ip = $_SERVER['REMOTE_ADDR'];
And if you want to echo it use
that is what i use
hey! this is a child’s play! such an easy thing! i said that coz i am 15 and a hard core PHP developer!!
I don’t understand something. 5 of my friends using different HOSTS in different CITIES used a script that logged each user’s IP address and time in a database and all their IP was exactly the same as mine. I used $_SERVER['REMOTE_ADDR']
Hey ben, all of your IP’s are the same since all of you are using the same ISP or the same main ISP:
user1->ISP1->main_isp->internet
you->ISP3->main_isp->internet
So the website actually detects your main_isp IP address since none of you have a dedicated IP address on the internet.
They are all behind the same proxy-server. In that case $_SERVER['REMOTE_ADDR'] provides you with the ip-address of the proxy-server.
This function will determine the real ip-adress:
function ipCheck() { if (getenv('HTTP_CLIENT_IP')) { $ip = getenv('HTTP_CLIENT_IP'); } elseif (getenv('HTTP_X_FORWARDED_FOR')) { $ip = getenv('HTTP_X_FORWARDED_FOR'); } elseif (getenv('HTTP_X_FORWARDED')) { $ip = getenv('HTTP_X_FORWARDED'); } elseif (getenv('HTTP_FORWARDED_FOR')) { $ip = getenv('HTTP_FORWARDED_FOR'); } elseif (getenv('HTTP_FORWARDED')) { $ip = getenv('HTTP_FORWARDED'); } else { $ip = $_SERVER['REMOTE_ADDR']; } return $ip; }it do not work if client computer is using ISA Server.
but code is working fine if client is connected with DSL , or modem direct internet connection.
can any one provide how do I resolved issue on intranet application/ Client is using ISA
how can i get the ip address of the client requesting a particular url?
if possible give me a php code for the same..
Yay;
Thanks it’s working fine !
supose am chatting with my friend using gtalk how would i get his ip address. [what command do i got to use in DOS]. what i got his ip what command [DOS} do i use to get his host name.
One more thing to what command to view that a specified computer is online or not.
Seems not to work for ‘localhost’ but works well with other IPs in the system
Why do you have 2 x same conditions in this script ?
elseif (getenv(‘HTTP_X_FORWARDED_FOR’)) {
$ip = getenv(‘HTTP_X_FORWARDED_FOR’); x 2
}
and
elseif (getenv(‘HTTP_FORWARDED’)) {
$ip = getenv(‘HTTP_FORWARDED’); x 2
}
they arent 2 same conditions in the script marco, if you check back you will notice all the conditions have a slight difference
Can any post a simple ip detection script or code. i need it please.
thanks and thanks
