How to get ipv4 in php
Many times we need to get the IP address of the visitor for different purposes. It is very easy to collect the IP address in PHP. PHP provides PHP $_SERVER variable to get the user IP address easily. We can track the activities of the visitor on the website for the security purpose, or we can know that who uses my website and many more. Show The simplest way to collect the visitor IP address in PHP is the REMOTE_ADDR. Pass the 'REMOTE_ADDR' in PHP $_SERVER variable. It will return the IP address of the visitor who is currently viewing the webpage. Note: We can display this IP address on the webpage and also even can store in database for many other purposes such as - for security, redirecting a visitor to another site, blocking/banning the visitor.Get the IP address of the website$_SERVER['REMOTE_ADDR'] - It returns the IP address of the user currently visiting the webpage. For example Output But sometimes the REMOTE_ADDR does not return the IP address of the client, and the main reason behind is to use the proxy. In such type of situation, we will try another way to get the real IP address of the user in PHP. Output Flowchart: The flowchart for the above program will be like given below. Get the IP address of the websiteWe can also get the IP address of any website by its URL. Pass the URL of the website inside gethostbyname() function. For example Output IP Address of Google is - 172.217.166.4 IP Address of javaTpoint is - 95.216.57.234 Whatever you do, make sure not to trust data sent from the client. However,
they can be behind a proxy server in which case the proxy may have set the This means that if you are going to save the If you are going to save the IP to a database as a string, make sure you have space for at least 45 characters. IPv6 is here to stay and those addresses are larger than the older IPv4 addresses. (Note that IPv6 usually uses 39 characters at most but there is also a special IPv6 notation for IPv4 addresses which in its full form can be up to 45 characters. So if you know what you are doing you can use 39 characters, but if you just want to set and forget it, use 45). answered Jun 9, 2010 at 5:15

KeaserKeaser 3313 silver badges6 bronze badges Here's a bit of code that should pick a valid IP by checking through various sources. First, it checks if 'REMOTE_ADDR' is a public IP or not (and not one of your trusted reverse proxies), then goes through one of the HTTP headers until it finds a public IP and returns it. (PHP 5.2+) It should be reliable as long as the reverse proxy is trusted or the server is directly connected with the client.

It will break your IP addresses, and give them all the same value. Fortunately they have some server headers available too.

In PHP the last option to get the public IP should always be Here is a workaround to get the validated IP address of the client.
As you can see here $_SERVER["REMOTE_ADDR"] is our last option to the IP. After receiving the IP we also validate the IP to ensure quality and security. answered Dec 3, 2021 at 17:59
