Not sure about this one, I am trying to execute a SQL query to retrieve
records then loop over the records and display X amount per line. Any
help is appreciated.
$sql = @mysql_query( SELECT * FROM subnets, $db );
$num = @mysql_num_rows( $sql );
$subnets .= table width=\100%\trtd

X ammount of what per 'line'? db records (or elelphants)?
and by line do you mean 'html table row'?
assuming I got that correct,
This is the code I went with and it works like a charm! Thank you very much
M. Sokolewicz!
echo {$row['name']}br /{$row['description']};
would work, just like all of the following would also:
echo $row[name]br /$row[description];
echo $row['name'].br /.$row['description'];
and a couple of others
Holla,
Maybe someone knows how to improve for loops
performance? When generating 1000's of pages, it
oads in 10-20 seconds. Maybe there is some
solution I don't know about?
Thanks!

If you only generate 100s of pages, it'll probably load about ten times
faster...

Hey, would anyone know offhand, if its faster to create a temp array,
fill it via loop, and then set a class property to that array, or to
simply fill the class property via loop..
to clearify.
would the following example be faster or slower had i simply done
$this-myArray[$i] = $i;

here's how i would do it (coding styles aside):
function MyClass()
{
$limit = 100;
$i = -1;
while(++$i $limit)
{
$this-myArray[] = $i;

Don't forget poor old range:
$this-myArray = range(0, 99);

Hi All,
I've been banging my head for several hours now.
I've got a mssql backend.
What I want to display is;
Date 1
Item 1
Item 2
Item 3 ... etc
Date 2
Item 1
Item 2
Item 3 ... etc
Here's the code I've been fighting with;
$query = select distinct wn_pdate
Sorry...,
Line 17 is: print trtda href=\$id\$row2[$rtxt]/a/td/tr;

i don't know the answer to either of those questions but if it's
complaining of an undefined index you might want to try
Using print_r($var) shows that the vars are returning the right values, and
where they're supposed to. Right in between the error messages. Doh.

You're doing it wrong then (I think).
1. You should always initialize your loop counters.
i.e.
$x = 0;

I'm unclear as
where is $row['BillPeriod'] set? and what is its value?

it works for me just the way you have itexcept of course that you are
telling it to only print to y because you are saying z

will print out a right down to yz

and it prints 1 thru to 10
