[PHP] Running for loop and concat. variables...

[Jeff Lewis]

I have a page with about 80 checkboxes on it.  The values are names and my users are 
to select names.  Now on the next step I want to be able to list all names processed.  
I thought a for loop would be best but am having problems.  $ffromx is the number of 
checkboxes generated in the previous step.  So I want to step through each to make 
sure that they were checked or not and then display them.

for ($i = 0; $i <= $ffromx; $i++) {
   if ($ffrom.$i){
       echo $ffrom.$i."<BR>";}
}
