The simplest way to collect the visitor IP address in PHP is the REMOTE_ADDR. Pass the 'REMOTE_ADDR' in PHP $_SERVER variable. It will return the IP address of the visitor who is currently viewing the webpage.
First, click on your Start Menu and type cmd in the search box and press enter. A black and white window will open where you will type ipconfig /all and press enter. There is a space between the command ipconfig and the switch of /all. Your ip address will be the IPv4 address.
$_SERVER['REMOTE_ADDR'] Returns the IP address from where the user is viewing the current page. $_SERVER['REMOTE_HOST'] Returns the Host name from where the user is viewing the current page. $_SERVER['REMOTE_PORT']
For getting the IP Address we have to include use Illuminate\Http\Request; in the controller and then add the code of the below pre tag. It will give the IP address of the network. $clientIP = \Request::ip(); dd($clientIP);
The simplest way to get the visitor’s/client’s IP address is using the $_SERVER['REMOTE_ADDR'] or $_SERVER['REMOTE_HOST'] variables.
However, sometimes this does not return the correct IP address of the visitor, so we can use some other server variables to get the IP address.
The below both functions are equivalent with the difference only in how and from where the values are retrieved.
getenv() is used to get the value of an environment variable in PHP.
// Function to get the client IP address
function get_client_ip() {
$ipaddress = '';
if (getenv('HTTP_CLIENT_IP'))
$ipaddress = getenv('HTTP_CLIENT_IP');
else if(getenv('HTTP_X_FORWARDED_FOR'))
$ipaddress = getenv('HTTP_X_FORWARDED_FOR');
else if(getenv('HTTP_X_FORWARDED'))
$ipaddress = getenv('HTTP_X_FORWARDED');
else if(getenv('HTTP_FORWARDED_FOR'))
$ipaddress = getenv('HTTP_FORWARDED_FOR');
else if(getenv('HTTP_FORWARDED'))
$ipaddress = getenv('HTTP_FORWARDED');
else if(getenv('REMOTE_ADDR'))
$ipaddress = getenv('REMOTE_ADDR');
else
$ipaddress = 'UNKNOWN';
return $ipaddress;
}
$_SERVER is an array that contains server variables created by the web server.
// Function to get the client IP address
function get_client_ip() {
$ipaddress = '';
if (isset($_SERVER['HTTP_CLIENT_IP']))
$ipaddress = $_SERVER['HTTP_CLIENT_IP'];
else if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))
$ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_X_FORWARDED']))
$ipaddress = $_SERVER['HTTP_X_FORWARDED'];
else if(isset($_SERVER['HTTP_FORWARDED_FOR']))
$ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_FORWARDED']))
$ipaddress = $_SERVER['HTTP_FORWARDED'];
else if(isset($_SERVER['REMOTE_ADDR']))
$ipaddress = $_SERVER['REMOTE_ADDR'];
else
$ipaddress = 'UNKNOWN';
return $ipaddress;
}
In PHP 5.3 or greater, you can get it like this:
$ip = getenv('HTTP_CLIENT_IP')?:
getenv('HTTP_X_FORWARDED_FOR')?:
getenv('HTTP_X_FORWARDED')?:
getenv('HTTP_FORWARDED_FOR')?:
getenv('HTTP_FORWARDED')?:
getenv('REMOTE_ADDR');
$ipaddress = '';
if ($_SERVER['HTTP_CLIENT_IP'] != '127.0.0.1')
$ipaddress = $_SERVER['HTTP_CLIENT_IP'];
else if ($_SERVER['HTTP_X_FORWARDED_FOR'] != '127.0.0.1')
$ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
else if ($_SERVER['HTTP_X_FORWARDED'] != '127.0.0.1')
$ipaddress = $_SERVER['HTTP_X_FORWARDED'];
else if ($_SERVER['HTTP_FORWARDED_FOR'] != '127.0.0.1')
$ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
else if ($_SERVER['HTTP_FORWARDED'] != '127.0.0.1')
$ipaddress = $_SERVER['HTTP_FORWARDED'];
else if ($_SERVER['REMOTE_ADDR'] != '127.0.0.1')
$ipaddress = $_SERVER['REMOTE_ADDR'];
else
$ipaddress = 'UNKNOWN';
