Hi all,
I'm using this code to display the current time for our location on

$theMinute = $theTimeIs['minutes']; // make minutes
under 10 show two digits
$theSecond = $theTimeIs['seconds'];

$theHour = $theHour - 12;
$dn = PM;
} else {
$dn = AM;
}
echo $theHour:$theMinute:$theSecond $dn;

It works great except for one small detail. If the time is 3:04:02,
it is displayed as 3:4:2 which, of course, is very odd looking. So I
corrected it as follows:
?php
date_default_timezone_set('America/Los_Angeles');
$theTimeIs = getdate(time());
$theHour = $theTimeIs['hours'];
if (strlen ($theTimeIs['minutes']) 2) {
$theMinute = 0 . $theTimeIs['minutes'];
} else {
$theMinute = $theTimeIs['minutes'];
}
if (strlen ($theTimeIs['seconds']) 2) {
$theSecond = 0 . $theTimeIs['seconds'];
} else {
$theSecond = $theTimeIs['seconds'];
}
if($theHour 12){
$theHour = $theHour - 12;
$dn = PM;
} else {
$dn = AM;
}
echo $theHour:$theMinute:$theSecond $dn;
?
It works, but is there a better way to do it?
Thanks,
Frank
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));

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.
Hosted servers are basically a trade off between doing it yourself and
paying someone else to do it. The initial choice is between installing
your own servers or spend the money to rent servers from someone else.
Most of the time it is actually the network bandwidth issue that decides
this. Can you afford a network connection that will handle the peak
loads but be unused most of the time?
But once you decide to pay someone else, you have another set of trade
offs to negotiate. What services do they provide? What systems do they
offer? How do they manage version control and updates? Are they PCI
compliant? There are a wide range of options available in the market.
Not all of them will fit your specific needs.
We just moved most of our servers from a physical hosting service to a
managed service. Where we used to maintain the OS and all software on
the server, the new service now handles that for us. The trade off is
that now we have to settle for the server package they offer. That means
we get the versions of Apache, PHP and PostgreSQL that were included in
the last production release of RHEL. If we want a newer version of PHP,
we have to take over maintenance of that component. It becomes our
responsibility to install the updates, patches, etc., for that
component.
Once you get beyond a private web site these types of decisions become
part of the management process, just as make or buy decisions are part
of the hardware procurement process. There are people out there making a
good living just guiding companies through this decision making process.

Re: [PHP] Is there limitation for switch case: argument's value?
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;
}

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

RE: [PHP] SESSION VARIABLES ACROSS DIFFERENT WINDOWS/TABS
Hi Jamie. Thanks. Good info. I knew something changed somewhere. This works like a charm in IE8..never saw the New Session option under file...me bad !! Greetings. -Original Message- From: Jaime Bozza [mailto:jbo...@mindsites.com] Sent: 20 August 2009 09:49 PM To: Leon du Plessis; 'Floyd Resler' Cc: a...@dotcontent.net; php-general@lists.php.net 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.

Having a different session start up for each window for tab would be a major pain. Why? People must please try and understand what I mean by NEW. It does not apply to windows/tabs being opened from a link or request. Imho, keeping the session per domain sounds wrong, it does not mean it is. It would have been nice if: Browser/tab one - my login detail container A. Browser/tab two - my admin login container B. (tabs/windows opened from browser one, then inherits container A naturally) (Closing browser one, then destroys container A then naturally only) NOT Domain.com - one session container only.

-
Using include ../Engine/Main_prog.php won't work for you in a production
environment. You need to create a path.php file that defines the absolute
path to the engine for each website, and include it at the top of your
website script. Then you can do something like:
include ENGINEPATH.Main_prog.php;
You can have different path files, one for dev and one for live, that allows
you to use the same scripts for both environments and just use the
appropriate path definition script.
E.g. Windows path.php
define('ENGINEPATH','../Engine/');
Linux path.php
define('ENGINEPATH','/usr/home/Engine/');
You shouldn't really have permission problems as long as your website and
engine are on the same server. I do something similar where the bulk of my
code is below doc root, and I use path files to find the main system
directories. The beauty of it is you can change your mind about directory
structures, and just change the path file definitions without making any
changes in the application code (my path file defines about 20 directories).
It also lets you do dev on a Windows pc and deploy on a *nix box without any
problems - just use a different path file for each.
One other advantage it will give you for your particualr design is that you
can have multiple engines per server (e.g. Engine1, Engine2, etc) so that
you can bring one engine down for upgrade while still keeping sites running
on the other engines.

Subject: Re: [PHP] Is there limitation for switch case:
argument's value?
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,
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;
}

Re: [PHP] HTML text extraction
Hello, on 08/18/2009 05:37 AM leledumbo said the following: Usually, a website gives preview of its articles by extracting some of the first characters. This is easy if the article is a pure text, but what if it's a HTML text? For instance, if I have the full text: p bla bla bla ul liitem 1/li liitem 2/li liitem 3/li /ul /p and I take the first 40 characters, it would result in: p bla bla bla ul liitem As you can see, the tags are incomplete and it might break other texts below it (I mean, other than this preview). I need a way to solve this problem. You may want to try these HTML parser classes. They can parse (and even validate) HTML and return an array of tag or data elements. You can use it to pick the first tags and data you. Then you you the RewriteElement function to regenerate the HTML. http://www.phpclasses.org/secure-html-filter -- Regards, Manuel Lemos Find and post PHP jobs http://www.phpclasses.org/jobs/ PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Re: How do I extract link text from anchor tag as well as the URL from the href attribute
Hello,
on 08/16/2009 04:33 AM chrysanhy said the following:
I have the following code to extract the URLs from the anchor tags of an
HTML page:
$html = new DOMDocument();
$htmlpage-loadHtmlFile($location);
$xpath = new DOMXPath($htmlpage);
$links = $xpath-query( '//a' );
foreach ($links as $link)
{ $int_url_list[$i++] = $link-getAttribute( 'href' ) . \n; }
If I have a link a href=http://X.com;/a, how do I extract the
corresponding which is displayed to the user as the text of the link
(if it's an image tag, I would like a DOMElement for that).
Thanks
You may want to try this HTML parser class that comes with filter class
and an example script named test_get_html_links.php that does exactly
what you ask.
