if $Count1 is never referenced after this, then certainly this
assignment operation is redundent. but assignment is not the ONLY
operation of this statement. if u hav not noticed a post increment
operator has been used which will affect the value of $Count as well,
and this operation is required for the script to work.
the script should work even if u replace
$Count1 = $Count++;
with
$Count++;

I have pagination set up and the number for pages "next" has a link but
the "next" does not. I have experimented with all sorts of
configurations of the code but the only thing that works (and this is
totally "off the wall") is to do this
*$Count* = *mysql_num_rows($results);*
$Count1=*$Count++;* // without this, the "next" does not do the link---
but there is no other $Count1 in the code either in the original page or
the include page.

There's a NICE video tutorial available on pagination over the internet. You
should watch it.
You are counting the number of rows of a result. And you are asking to
increase the count by 1. :D
Thats not realistic.
pagination is done with the help of mySQL's * LIMIT recNUMBER, count*
*
Look for "Pagination with PHP + MySQL" and watchit

What parameters are you pasing in the link? That will be the telling
point of what you are doing wrong. You could pass the search params
( though these are best kept in a session or cookie ) and the offset
counter to get the next block of results.
Sorry for top posting.

As an alternative you might consider;
$number = sprintf("%01.2f",$number);
There was a time many years ago you had to be careful doing math with
floats. Test, test and test some more.

a POSSIBLE work round.
see if u can use
http://in2.php.net/manual/en/function.error-get-last.php or
http://in2.php.net/manual/en/reserved.variables.phperrormsg.php but
they are not working as expected with xdebug. use them in the
__destruct function to check for an uncaught exception
alternatively.. this approach is NOT RECOMMENDED. use it only if u run
out of options
keep the destructor empty. catch the exception and call a function to
perform destruction and then unset the object.
at the end of script, check if the object is set, call the function to
perform destruction. (php dosent destroy the object if the exception
is caught)

Hi,
I'm having problems when i try to use the function scandir() in a Novell
Netware Volumen or a Windows Shared Folder
they both are mapped as a windows network drive, so i suppose i could access
them as local drive, but i can't. instead i receive this message:
Warning: scandir(R:\) [function.scandir]: failed to open dir: Invalid argument
in C:\WebServ\wwwroot\htdocs\index.php on line 3
Warning: scandir() [function.scandir]: (errno 22): Invalid argument in
C:\WebServ\wwwroot\htdocs\index.php on line 3
this is the script:
<?php
$dir = "R:\\"; //Some Windows Network Drive (Novell
Netware Volumen or a Windows Shared Folder)
$files1 = scandir($dir);
print_r($files1);
?>
i' m logged to novell as an administrator (testing only)
if i use scandir() in a local drive it works fine for example: scandir("D:\\")
i have appache server 2.0 installed on a WXP SP3 workstation (only for testing)
and a Novell Netware Server v5.0 used as a File Server, PHP 5.0.2
did i say something wrong in the previus post that nobody answer it? This is
the first time i have access to a mailing list and maybe i don't know how to
ask right?
Saludos,
Dedel.

try using the network path instead :) you have to do this for samba
drives on windows too.
$dir = '//machine.local/share/path';

That's what I was just about saying, in addition try to add the HTML
entities to the regular expression as well:
$string = preg_replace('/(?:& #34;|")(.*?)(?:& #34;|")/', '<font
color="color">"\\1"</font>', $string);
Also if you don't to get caught by the HTML validator you better surround
the color name with double quotes ;)

If I have something like $string = '"hello" there'; (the word hello is

Arrggg.
Don't use: "<font color=color>"hello"</font>"
The font tag is dead and embedded styling should moved to css.
There are lot's of ways to do this, here's one:
<span class="red"><?php echo('hello'); ?></span><?php echo(' there'); ?>
You might also check out first-child in css. That way you can make
"hello" in red and "there" in whatever the element color is in one
statement.

I'd go further on that and say don't call your class 'red', as it
doesn't do anything for semantic code, but that's just me trolling ;)

I was about to say the same thing *lol*. tis true though, the class
should be "doubleQuoted" or something similar. What happens when they
decide it should be blue?
span.red
{
color: blue;
}
Uh huh, uh huh, uh huh :)
Cheers,
Rob.

I fully understand, but I also see two side to this.
On one side, I agree that one should always keep attributes vague
enough so they can be anything, such as class="warning" and that way
the client may say "I don't want it red now, but orange" and it will
be easy enough to change.
On the other side, some attributes may be exactly what they claim,
such as class="center" or class="red". There is little confusion
about what those classes mean as compared to more vague terms. As
such, exact attributes are indeed semantic.
So as I see it, with *some* attributes it's a toss-up -- you can add
a layer of abstraction by making them vague OR you can use a more
exact (semantic) meaning. I don't find much fault with either way
provided that it's not a big problem later. The dividing line here is
one of how much work it causes.
Additional consideration, one can combine exact attributes, such as
class="center red" and it both works and is obvious.
I often have in my css, rules such as:
.center
{
text-align: center;
}
.red
{
color: red;
}
While it might not fit with the purest css, it works for me. YMMV. :-)
Cheers,
tedd
