hi I have a table with rows and each row contains a checkbox ( array)

echo(td width=15 bgcolor=#9FD9FFinput type=checkbox name=chkR[]
value=. $chkSessionF[$i] ./td);
Firstly you should be putting double quotes around every value in your
HTML tags.
Revised: (watch wrap)
echo td width=\15\ bgcolor=\#9FD9FF\input type=\checkbox\
name=\chkR[]\ value=\{$chkSessionF[$i]}\/td;
I also changed
. $chkSessionF[$i] .
into
{$chkSessionF[$i]}
.
You can do it either way. I prefer the latter.
If you're not sure what a value is use print_r() to determine it.
echo pre;
print_r($chk);
echo /pre;
Quick side note on the above code:
You cannot write it like:
echo pre.print_r($chk)./pre;
It will not work.
can anyone help. this is very strange.
I think your problem may just be the quotes around the values in the
HTML. Give it a shot.
hth,
chris.

From: Chris W. Parker [EMAIL PROTECTED] echo pre.print_r($chk)./pre; It will not work. You can do this though: echo pre, print_r($chk), /pre; Well heck, that makes things easier! What's the difference between using , or . for concatenation? (I thought they were the same.) Using a comma is just like using another echo command. So for the above, you're effectively saying: echo pre; echo print_r($chk); echo /pre; Note that print_r() will (by default) return a 1 (TRUE) upon success, so you end up with a 1 being printed at the end of your data. You could also use this method: echo pre.print_r($chk,TRUE)./pre; The TRUE causes the output of print_r() to be returned instead of printed automatically. The benefit to this method is that you don't end up with the 1 being printed. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Oh ok, I get it.
I've heard statements about passing multiple arguments to echo being
faster than using concatenation, but every benchmark I've tried
myself shows them to be nearly identical. Feel free to try it
yourself and post your results. :-) I'd be curious to see if others
reach the same conclusion.
I tried this, and I think the comma was just slightly faster than the
period. But then again I didn't always get consistent results because I
was trying this out on a machine that is not very fast so the speed at
which is processes something varies quite a bit.
My conclusion was that it's not fast enough to bother changing all my
code, or start writing in a new way.
Although during some testing I did find that writing loops in the
following way is faster than normal.
$counter = -1;
while(++$counter $amount)
{
// do stuff
}
It made a big enough difference on my slow machine to merit me writing
as many loops in this way as I can. (I think.)
Chris.
