How do I fetch a current visitors ip address, and turn it into a variable?

Hello

 

How do I fetch a current visitors ip address, and turn it into a variable?

 

The visitor should only be able to enter the same form once, so I want to compare the current visitor ip address with ip addresses in the database to achieve this.

 

Best regards Morris

It's already in the array variable $_SERVER, but if you wish to add it to a separate variable you can use:

 

$ip = $_SERVER['REMOTE_ADDR'];
