What's wrong with using the date() function? You can have it output any
sort of format you wish. So, getting a 2 digit time in
hours:minutes:seconds you would put:
date("H:i:s");

Thanks, Ash. I had tried that before but I couldn't find a way to
make it display in 12 hour time, so I went with the other method. I
guess I didn't look hard enough. =;)
This works:
echo (date("g:i A"));

Thanks, Jonathan! I learned two new functions today! Both work
great but I think I like sprintf for this application better since
it's more succinct.
echo sprintf('%02d', $theMinute);
echo (str_pad($theMinute,2,"0",STR_PAD_LEFT));

Uh. If you MUST do this nonsense, then at least do this instead and not
"echo sprintf":
printf('%02d', $theMinute);

I've written an application that depends heavily on Tidy for cleaning up user
inputed text.
Unfortunately, some shared hosts won't install the extension for my clients.
Is there a way I can install a stand alone version using FTP with access only in
a directory where my program resides. The hosts have given me restricted FTP to
the dir.
Or, does anyone know of a stand-alone php class that emulates the tidy
extension. I've looked; but, not found any.

Hi Nathan,
I agree with you, and I believe that there are many persons who don't like the
idea of hosting all their applications on a third party server. IMO there are
some advantages and disadvantages to doing so but that's a discussion in itself.
The good thing about Raxan's Embeddable Apps is that you have control over the
source code. With the ShoutBox example you can download the framwork along
with the application and copy it to your own servers. No need to host the apps
on third party servers.
Some benefits of Raxan Embeddable Apps:
----------------------------------------------------------------
1. Works in just about any web page
2. Easy to deploy and configure
3. Reusable and Shareable
I believe that one day we will see apps like Photo Galleries, Media players,
File Managers, Catalogs, etc that users can easily download and add to the
their web pages.
PS. I would like to invite everyone to download the framework, try the examples
and take a look at the source code. You will be amaze at what you can do with
Raxan PDI. - You can download it here:
http://code.google.com/p/raxan/downloads/detail?name=raxan-pdi.1.0.0b2.zip&can=2&q=

ive seen lots of third parties selling components in this manor. now that ajax
has hit the scene there are some really weird things going on.
i was just on a call yesterday where this company told us about their service,
which is delivered as one of these 'embedded' applications. this thing would
have its own navigation and display of content on our site in order to keep
folks clicking.
if you ask me, that just feels weird; having some other company like own a
piece of your app... however, it would be foolish not to admit that this is
the way things are trending and that there will only be more of it to come.

Hi,
I encounter a funny limitation here with switch case as below:
The value for $sum is worked as expected for 1 to 8, but not for 0.
When the $sum=0, the first case will be return, which is "sum=8".
Is there any limitation / rules for switch case? Thanks for advice!
Keith
$sum=0;
switch($sum)
{
case ($sum==8):
echo "sum=8";
break;
case ($sum==7 || $sum==6):
echo "sum=7 or 6";
break;
case ($sum==2 || $sum==1):
echo "sum=2 or 1";
break;
case 0:
echo "sum=0";
break;
default:
echo "sum=3/4/5";
break;
}

I've never understood why people use switch statements like this as in
reality you are using it more like an if/else block, but anyway.
The reason why your code is not working is that you are passing into
the switch the value of 0, or false, which means that when any of
those $sum == N conditionals comes up as false (say $sum == 8 ), then
that is what is returned because they match up. In PHP's eyes, 0 ==
false in switch statements.
To fix your code, change the switch( $sum ) to switch( true ):
switch( true )
{
case ($sum == 8):
echo "sum=8\n";
break;
case ($sum == 7 || $sum == 6):
echo "sum=7 or 6\n";
break;
case ($sum == 2 || $sum == 1):
echo "sum=2 or 1\n";
break;
case ($sum == 0):
echo "sum=0\n";
break;
default:
echo "sum=3/4/5\n";
break;
}
Or, write your switch like this:
switch( $sum )
{
case 8:
echo "sum=8\n";
break;
case 6:
case 7:
echo "sum=7 or 6\n";
break;
case 1:
case 2:
echo "sum=2 or 1\n";
break;
case 0:
echo "sum=0\n";
break;
default:
echo "sum=3/4/5\n";
break;
}
Regards,
Adam.

Hi Keith,
Try replacing 'switch($sum)' with 'switch(true)'.
Note that unless you have very good reasons for using a switch
statement like this, and know exactly why you're doing it, it's often
better just to use it in the normal fashion. i.e.:
switch ($sum)
{
case 8:
break;
case 7:
case 6:
break;
case 2:
case 1:
break;
case 0:
break;
default:
break;
}
Some people like the syntax you've presented but honestly, there's
usually a better way to do it.
This is also somewhat faster too, although you may only notice the
difference in very tight loops where you're counting every nanosecond.
Regards,
Torben

Subject: RE: [PHP] SESSION VARIABLES ACROSS DIFFERENT WINDOWS/TABS
Leon,
This is really just a function of the browser. When a session cookie is
created, if the browser is setup for a single instance, that's the session
cookie it'll use for *any* request to that domain. This functions
differently depending on what browser you're using.
For example:
Firefox - All windows, tabs, etc, under the same profile will use the same
session. If you create profiles, you can have different sessions.
IE7, IE6 - All tabs or windows opened from clicks will share the same
instance/session. Starting IE from the icon will open up a "new"
instance/session. This worked great if you wanted to run two different
sessions at the same site/domain. Just start IE up from the icon again and
you'd have a new session.
IE8 - IE8 model changed, so that all browser windows, tabs, etc., run under
the same frame/session, much like Firefox. Clicking the IE icon again now
just keeps the same frame and thus the same session. Originally, this
sounded like a big problem, but IE8 introduced a new feature - File Menu ->
New Session. This will open up a new window that will be a separate frame
that will not use current session cookies.
Here's just one of many links, but gives some helpful hints on the IE side:
http://blogs.msdn.com/ie/archive/2009/05/06/session-cookies-sessionstorage-a
nd-ie8.aspx
And another:
http://blogs.msdn.com/askie/archive/2009/05/08/session-management-within-int
ernet-explorer-8-0.aspx
One of the issues now is that if you close IE, your session does not
disappear. In the past (IE7/IE6), your session would disappear if you
closed a browser window that you opened yourself, but it *wouldn't*
disappear if you closed a browser window that was opened by a click from
Outlook or another program. This was a bit inconsistent. I won't argue
whether or not their "fix" was the best way to go, but now it's at least
consistent.
Note - In Firefox, not even "Private Browsing" separates the session
cookies. If you start Private Browsing (Firefox 3.5), log into a site, then
start a new browser window from the icon (that isn't in Private Browsing
mode), it shares the session cookies. (Before you ask, I just checked this
to be sure.)
IE8 "InPrivate Mode" is a totally separate session, cookies and all. This
could possibly be another way for you to run multiple sessions against the
same domain. OTOH, multiple InPrivate sessions running at the same time
share the same frame, so they share the same session, so it would only be
good for a single new session. If you need more, just use File - New
Session.

I am developing an idea for a website engine which can be shared between
several different
websites. Each website would have its own directory under a common root
directory, and the
engine would be in a separate directory Engine:
Root
Website_1.com, Website_2.com, Engine
The website directories would each contain the design data for that website,
consisting
basically of a mixture of text files and images. The various pages would be
loaded by
loading index.php from the website root directory, and specifying a number of
parameters
e.g.
http://www.corybas.com/index.php?path=Holidays&level=0&item=0
I have the minimum amount of code in index.php -- just enough to set some
parameters to
identify the website, and then include ../Engine/Main_prog.php. This in turn
can include
any of a large number of other include files to carry out particular functions.
I have the prototype working nicely on my PC, and on a stand-alone basis on a
server, but
now I am trying to upload the multi-website version to a public host, and am
encountering
a number of problems, mainly because I have never done any serious work with
UNIX, and the
host support staff don't understand what I am trying to do.
The problems mainly relate to setting permissions to allow the website to
access the
engine code. I only have a rough idea of how the permissions work, but I think
that to
include engine code the website has to have read and execute rights to it, and
I also
think that so far as the engine is concerned the website will count as 'other'.
(I can
easily arrange that all temporary files are written in the website directory.)
I suspect that rather than including the engine code in index.php, it would be
better to
call functions in it, so that the website only required 'execute' rights, but I
don't know
of any way to do this without having anything running permanently on the
server. Can
anyone suggest how it can be done?
