You are right, mysql_fetch_array() uses MYSQL_BOTH by default. I have just corrected 
the example, and
added some comments, so it works OK...

Do not expect it to show up in a day, as the HTML
generation from XML is done daily.

On the "LV. MySQL Functions" page of the PHP Manual, there is a piece of example code, 
demonstrating how to connect to MySQL, send a query and output the result of that 
query.  The part I'm concerned about goes like this:

print "<table>\n";
while ($line = mysql_fetch_array($result)) {
    print "\t<tr>\n";
    while(list($col_name, $col_value) = each($line)) {
        print "\t\t<td>$col_value</td>\n";
    }
    print "\t</tr>\n";
}
print "</table>\n";

When I reproduced this example, something went wrong.  Specifically, every value was 
printed twice.  I'll elaborate on that - If my source table looked like this:

id   name
---------
1    blah
2    foo
3    bar

Then the above code produced:

1  1  blah blah
2  2  foo  foo
3  3  bar  bar

My guess is that, because mysql_fetch_array supplies BOTH associative and numerical 
indexes, using the "while(list = each)" format references two key/value pairs for 
every one.

When I used mysql_fetch_assoc instead of mysql_fetch_array, the example worked 
perfectly.  I assume that it would also work if you specified MYSQL_ASSOC or MYSQL_NUM 
for mysql_fetch_arry, but I haven't tested it.

Feel free to email me if you need more detailed information.

Sincerely,
BJ
