Quick Job: -Write a PHP code snippet to to get Visitor's IP Address || Golang Experience will help

If you are an experienced PHP developer and have a good understanding of HTTP/Proxy, please continue. We are trying to get the IP address from the visitors if they are using SOCKS5. Say if the user is using a proxy from Japan (say 1.1.1.1), our PHP scripts need to get that example Proxy IP address (1.1.1.1). But in PHP, $_SERVER[‘REMOTE_ADDR’] doesn’t return the correct value, also, that example IP (1.1.1.1) is not in the X-FORWARD-FOR, or CLIENT-IP headers. Interesting enough, using the 3rd party service such as [login to view URL] will return the correct value. A open source Go Implementation will get the correct value too. [login to view URL] So we need a code snippet which has same logic of [login to view URL] to get the visitor’s IP address.
