Hi,
I try to construct an array such that each element of it is another
array returned by the fetch_array_function:
for ( $i = 1; $i<=$n; $i++ )
{
$ar[$i] = mysql_fetch_array( $result );
print "$ar[$i][fieldname]\n";
}
It prints "Array[fieldname]".
If I replace $ar[$i] by $ar everything works fine! Could you pleas
help me with that?

or
print "{$ar[$i]['fieldname']\n";
[fieldname] will give you an E_NOTICE if enabled (and it should be on
your development system).

A notice is not thrown in this case because the key is already within
double quotes. The problem is fixed by the necessity to use { }'s when
using multi-dimensional arrays within double quotes. I normally use this
method. To get PHP to throw a NOTICE, remove the single quotes from your
second example.

print_r will show you the internals
no point for you to control the index yourself
$a[] = 2;
$a[] = 3;
$a[] = 5;
print $a;
print_r($a);
?>
$a = array(array("a"=>1, "b"=>2));
print "{$a[0]['b']}";
?>
you obviously forgot to close your }
$a = array(array("a"=>1, "b"=>2));
print "{$a[0][b]}";
?>
this gives you notice,
php ends the variable name at the most convenience spot

Yes, that's what I said. When using multi-dimensional arrays within
double-quoted strings you must use the { }'s... and when you use the {
}'s you must use single quotes around the key names. PHP does not search
for CONSTANTS within double-quoted strings, there is a very specific
reason for it.
