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.

Your terminology is a little mixed-up, you are not dealing with a
'register global' you are dealing with a variable and an array. If you
will do this...
print_r($_GET); You will see am array. then you can do something like
this..(without the substring manipulation above)
for($i = 0; $i < count($_GET); $i++){
echo $_GET[$i] . "\n";
}
