Php request remote ip

How to get user IP address, OS, browser and country in PHP

As a developer, you may want to collect your website users’ information such as their IP addresses, their operating system, the browser, and the country from which they are accessing the site.

You may do this to track user activities for security reasons or for a better user experience in order to serve users with content that is more personalized content for their region/country.

How to collect user IP address

It is very easy to get user IP address in PHP using the superglobal variable $_SERVER which provides the server and environment-related information.

Below are the following ways in which you can collect the IP using the $_SERVER variable:

1. $_SERVER[‘REMOTE_ADDR’] — This contains the real IP address of the client. That is the most reliable value you can find from the user.

2. $_SERVER[‘HTTP_CLIENT_IP’] — This will fetch the IP address when the user is from shared Internet services.

3. $_SERVER[‘HTTP_X_FORWARDED_FOR’] — This will fetch the IP address from the user when he/she is behind the proxy.

The simplest way is just to collect the REMOTE_ADDR as below:

However, the user can be behind a proxy server in which case the proxy may have set the $_SERVER[‘HTTP_X_FORWARDED_FOR’] and in this case, the $_SERVER[‘REMOTE_ADDR’] fails to return the correct IP address of the user.

Use the sample code below to get the more accurate one:

 else if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) < $ip = $_SERVER['HTTP_X_FORWARDED_FOR']; >else < $ip = $_SERVER['REMOTE_ADDR']; >echo "IP address is: ".$ip; 

How to get user OS and browser

You also correct the client information in PHP through the use of the variable $_SERVER.

Simply use the code below:

The above code should give the result as below:

Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0

If you just want to simply collect the OS name and the browser name and version, simply do this:

"; echo "Browser: ".end(explode(" ",$client)); 

It should give you the result as below depending on your OS and browser:

Operating system: Ubuntu
Browser: Firefox/91.0

How to get user country

It is possible to get the country information of the website user, using their IP address with the help of the geoplugin.net API.

Simply get the PHP curl GET request as below:

This request will give you a JSON response as below:

You can extract the JSON data to PHP variables for user as shown below:

geoplugin_continentName."
"; echo "Country Name: ".$params->geoplugin_countryName."
"; echo "Country Code: ".$params->geoplugin_countryCode."
"; echo "City Name: ".$params->geoplugin_city; 

The above code should print out the result as shown below:

Continent Name: Africa
Country Name: Kenya
Country Code: KE
City Name: Nairobi

Conclusion

It is possible to collect important user information on your website for specific reasons such as tracking and security reasons, customizing the site content based on their region, web browser, etc.

PHP API get requesters IP Address [duplicate]

APIs can be accessed from both server-side PHP scripts and client-side Javascript in browsers using AJAX, which is more commonly used. For instance, snippets of Javascript for Google Analytics, Google Maps, and more can be found on many web pages, but the client browser actually makes the call to Google. In such cases, which are typical for most APIs, the client IP address is the only one visible, not the web server’s. Google (and other APIs) require registration for a free API key in such situations. You usually can’t trace it to a specific web server, but it does enable you to connect with the initial customer or developer who registered for the API.

Generate a no-cost «API Key» for your website’s customers, developers, and users to monitor their activities.

The best way to get the IP is;

$ip = (!empty($_SERVER['REMOTE_ADDR'])) ? $_SERVER['REMOTE_ADDR'] : getenv('REMOTE_ADDR'); 

I’m skeptical that there’s a distinction between these two variables. Hmm.

The function getenv() provides access to all environment variables, including REMOTE_ADDR, which is registered by PHP as an environment variable for the script. In contrast, $_SERVER allows access only to the contents of the $_SERVER superglobal.

The conventional method is to employ $_SERVER for this purpose, even though there is no significant difference in terms of functionality.

To avoid server incompatibilities, it is advisable to use $_SERVER[‘REMOTE_ADDR’] instead.
