[PHP] Re: incrementing a register global

[Aaron Todd]

Thanks for all the suggestions.  I am going to plan on trying them out just 
to see some other ways of making it work.  I finally got it to work after 
hours of just playing around with the code.  Here is what I ended up doing:

for($i=1;$i<=$boxes;$i++){
  echo $_GET['name'.$i];
}

Moving the $i inside the bracket but not inside the single quote seem to 
make things happy.

Thanks,

Aaron

Just so there is no confusion...I mistyped the line:
  $names = substr(strrchr($_SERVER['QUERY_STRING'],"&"),7,1);

It should be a 5 instead of a 7 at the end:
  $names = substr(strrchr($_SERVER['QUERY_STRING'],"&"),5,1);

did you tried foreach() with $_GET ( or $_REQUEST ) ?


foreach ( $_GET as $key => $var )
{
echo $key . ' => ' . $var;
}


but this is not "incrementing a register global" but 'accessing a
superglobale array'
