Here’s a simple PHP function that allows you to target a specified IP address, and can therefore be used to show certain information to the developer or developing team…

Replace 123.456.78.90 with your real IP address…

// Only show to the ip address 123.456.78.90
if($_SERVER['REMOTE_ADDR']=='123.456.78.90') { 
   echo 'Special information for development team is as follows:';
   //echo $var1, etc...
}
