How to get the IP address 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.

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.

User IP Address - ::1

User IP Address - ::1
