incrementing a register global

I dont know it this is possible, but here it goes. Hopefully I cac explain it well enough for someone to understand. I am posting data to a php script. I have several variables that are the same except the number at the end is different. So the url of the called script will be something like: http://www.something.com/test.php?name1=Sam&name2=Bill&name3=Joe On my script I am using substr() and strrchr() to get the number of last variable: $names = substr(strrchr($_SERVER['QUERY_STRING'],"&"),7,1); I am then trying to run a loop to call each variable and just print it on the screen: for($i=1;$i<=$boxes;$i++){ echo $_GET['name'].$i; } This is where my problem is. And I dont know if this is even possible, but if you look at the echo line in the loop I am trying to add the number of $i to the register global. I dont get an error in doing this, but when I run the script I get the number of $i instead of the value of $_GET['name1'] Like I said, I hope I explained this good enough for someone to know what I am trying to do. If anyone has any suggestions or comments about doing something like this please let me know. Thanks, Aaron
