Yes - it is J and I. I tried using $i+1 in the echo originally but it
wouldn't run. That's why I created $j.
Interesting it wouldn't run.. perhaps that's a place to investigate?
And just what is wrong with the old cr/lf sequence? How would you
have done
it?
If it is being sent to a browser, which i suspect given the html
entities encoding, i would have used "<br />".
If it is being sent to a terminal or file, I would have used "\n".
What do you mean 'this alone .....'?
Merely that the construction I see shouldn't matter whether you use $j
or $i+1.

ok - here's the code in question.

{
$j = $i+1;
Am i reading this correctly: the first variable is j (jay) the second
variable is i (eye) ?
This alone doesn't explain anything...
$row = mysql_fetch_array($qrslt);
echo $j.'-'.$row['userid'];
Since this is the only place $j is used, try subbing in $i+1 and
see what
you get.
if ($row['user_priv']<> "")
echo ' ('.$row['user_priv'].')
';
This is really rather a strange way of getting a line break.
else
echo '
';
}
The output I get is:
1-smith5
f-ginerjm (M)
g-smith8
While the alpha parts are valid, the index is only correct for
the first
one
(0) obviously.

\r\n"; //If you
don't put \r\n or a space at the end of the echo then the beginning on
the next line is going to be interpreted as #101/#102/#103 aso (that i
figured when you wrote that putting a space in the beginning of the
echo solved the problem.
