there's one example of var-of-vars along with arrays below my rant <rant> var-of-var is almost always an evil thing. there are some rare instances where they're necessary, but i assure you that your script would be MUCH cleaner and easier to modify in the future if you used a simple array.
compare: $value = $form[$temp . $i]; to: eval('$valueofsize = $'. $temp . $i .';'); </rant> $form['size1'] = "hey"; $form['size2'] = "there"; $size1 = "hey"; $size2 = "there"; $loopcounter = 2; while ($i++ < $loopcounter) { $temp = "size"; eval('$valueofsize = $'. $temp . $i .';'); print $valueofsize; print $form[$temp . $i]; } ---------------- Scott Hurring - Internet Programmer GraphicType Services tel: 973.667.9486 web: http://www.graphictype.com/ pgp: http://graphictype.com/scott/pgp.txt ---------------- > -----Original Message----- > From: Mike Krisher [mailto:[EMAIL PROTECTED]] > Sent: Thursday, January 17, 2002 11:12 AM > To: [EMAIL PROTECTED] > Subject: [PHP] variable variables > > > I can not wrap my head around variable variables today, not awake yet or > something. > > For instance I trying something like this: > > while ($i<$loopcounter) { > $temp = "size"; > $valueofsize = $$temp$i; > $i++; > } > > this doesn't work obviously, $valueofsize ends up with a literal value of > "$size1".
