You use variables that hold the name of the variable you want to
access, and access it as $$varaiblename.
$i gives the value of "i".
$$i gives the value of the variable whose name is contained in "i".
<?
for (i=0;i<10;i++)
{
$idvalue = "id_$i";
$namevalue = "name_$i";
$roomnumvalue = "room_num_$i";
echo ($$idvalue.", ".$$namevalue.", ".$$roomnumvalue);
}
?>
