Matt,
Perhaps I could elaborate for you. When you run a mysql query through php
the function returns a result variable. This is not unlike a cursor that
you would use in oracle programming. This result set contains all the rows
returned by the query but you must take it a step further to gather the
values from the result set. A call to mysql_fetch_row() will return a
different row from the result set each time it is called until it is
empty. It's commonly placed in a while() loop so the function will continue
to be called until mysql_fetch_row() returns false. For each interation of
the loop an array is returned into $row my mysql_fetch_result() that is
indexed numerically by row number. These row numbers will match the order
of the columns as specified in your select clause or by column order in the
database if you did a select *. An alternative to mysql_fetch_row would be
mysql_fetch_array or mysql_fetch_assoc. These functions return an array as
well but it is associative meaning the elements can be accessed by column
name. For example: $row['name']. I personally prefer this method because
it makes the code a bit easier to read and I don't have to remember the
order of columns. The numerically indexed arrays are handy for dumping
table structures though because you can loop off the array size and don't
have to change your code if you change your database schema. This latter
technique is the one used by Bas in his example.
Hope that clears things up a bit.

Hi Baz,
Thanks for mailing back, would you care to explain this a little more so I
understand whats going on and how to use it
I can see that you are fetching the results of select * from - into and
array. and while there is records in the array you are echoing data, but I
am not sure on whats going on, and how to generate the table from these
results.
thanks,
Matt.

while ($row=mysql_fetch_row($result))
{
echo 1 $row[0]
for($x=1; $xcount($row); $x++)
if(!empty($row[$x]))
{
echo $x+1;
echo .$row[$x];
}
}
