yes... the "dimension" of an array is basically how many
brackets you put after the variable name...
1D = $this[];
2D = $this[][];
3D = $this[][][];
etc....

with a slight modification, that code works perfectly:
(see end of email for why you probably got a parse error)
<?php
$ary1 = array ("one","two");
$ary2 = array ("three","four");
$twod = array($ary1, $ary2);
while ( list ($rec_no,$ary) = each ($twod) )
{
echo ("Record No $rec_no:");
while ( list ($key,$val) = each ($ary) )
echo "$key=$val; ";
echo "<BR>\n";
}
?>
> // I want to use the above code to print something like
> // Record No 0:one, two
> // Record No 1:three, four
my code produces:
Record No 0:0=one; 1=two;
Record No 1:0=three; 1=four;
suppress printing $key, and you'll get the output you want.

if i use your code verbatim, i get a parse error becuase of the
variable name starting with a digit, but as for the error *you*
describe, when i put the loop inside of a function, and fail to declare
$twod as global, i get the same error:
"Warning: Variable passed to each() is not an array or object ..."
make sure you declare all globals as "global $varname" in your
functions... PHP is basically the reverse of almost every other
language (things are local by default, global by declaration)...
