That's not specific to PHP. It's just how http works, so it's the same
for ASP, Perl, I suspect Java and most (if not all) other languages.
There might be a language that sets a cookie when you assign a value
to a special cookie variable, but I'm not familiar with any.

Andrew



Unless I was doing something differently when I originally wrote this 
in PERL I don't recall having this issue. At that time I would set the 
cookie and then redirect (load the index with the full menu) if cookie 
existed.


Geez! now my $_SESSION isn't persisting to the next page when the 
screen refreshes. The only thing preventing me from gouging out my 
eyes right now is that I know I'll get this stuff. It's just a matter 
of time...




The problem that you are encountering is because the $_COOKIE array is 
populated when the script is executed.  More then likely the other 
languages that you used, would allow you to set a cookie and then they 
would enter them into the global array for you, and not make you wait 
until the next page load.


You could accomplish this yourself by making a wrapper function for the 
setcookie() function and have your function set the data using 
setcookie() and having it enter the data directly into the $_COOKIE array.


Something like this should do the trick

?php
/*
bool setcookie ( string $name
  [, string $value
  [, int $expire
  [, string $path
  [, string $domain
  [, bool $secure
  [, bool $httponly  ]] )
*/

function mySetCookie($name,
 $value=null,
 $expire=0,
 $path='/',
 $domain=null,
 $secure=FALSE,
 $httponly=FALSE) {

if ( is_null($domain) )
$domain = $_SERVER['SERVER_NAME'];

if ( setcookie( $name, $value, $expire,
$path, $domain, $secure, $httponly) ) {
$_COOKIE[$name] = $value;
return true;
}
return false;
}


?


Wow! very sweet!!

Thank you Jim. I'm getting my brain good and wrinkled today.

[PHP] optimilize web page loading

2008-03-26 Thread Alain Roger
Hi,

i would like to know if there is a way to know how long does a web page need
to be loaded into browser ?
this is interesting fact for me, as i will optimilize my PHP code in order
to reduce this time to minimum.

i was thinking to use some timestamp but as it will be in PHP, it mean that
it should take time from server and therefore it is not fully representative
from client browser time needed to load page :-(
purpose :
mywebpage.php - 23 s before optimalization
mywebpage.php - 12 s after optimalization

do you have any idea ?

Hi,

If you make use of Firefox, you can use the Yslow extension. This will 
show you the bottlenecks of the page loaded (images, stylesheets,

Not that this helps/hurts your observation.

What I find interesting is that the round function has a bias to round down.

I've proved it, but it takes a lot of calculations to demonstrate any

There's an old proverb that basically says that if you present a mule 
with two choices, (1) a easy, meandering path up the side of a mountain 
that triples the time it would take to get to the top, and (2) a 
brutally hard path that goes straight up the mountain, but would most 
certainly have a good chance of killing the mule if taken, the mule will 
take path number 2 each and every time.


It's the mule in me!  :)  I can't help myself. It's like sitting a pair 
of shoes down in front of a leprechaun; he can't resist the compulsion 
the shine and clean those shoes. I can't resist the compulsion to solve 
a problem by coding a solution for it.


I really enjoy programming. It satisfies a creative bent in me, but from 
time to time I do get very frustrated with it. Especially when, as in 
this case, it's only a cookie and an easy concept. What frustrates me is 
I know I'm missing something, but for the life of me I can't see it. 
Therefore the shoe that I'm compelled to clean and shine keeps dipping 
itself back into the mud.


For me moving from procedural PERL programming to OOP PHP feels like a 
paradigm shift! some of it coming back easily and some of it not so 
easily. Ya know... old dog new tricks... that sort of thing. But if I 
don't challenge myself and learn new things I could run the risk of 
getting stuck in a rut of thinking the same way about things and well... 
never mind... shit! more mud on that shoe again.  :)

 If they open a new window by clicking on IE (say, on the desktop, the
 QuickLaunch bar, or the Start menu), Windows actually opens a new,
 totally separate process of IE along side the first. The new one will
 share any persistent cookies with the first, since they are written to
 the file system, but sessions do not usually use persistent cookies.
 As long as your users are opening the new window by clicking a link or
 by pressing  Ctrl+N from the first window, the session information
 *should* remain in tact.

 Andrew

 should - but don't :D
 you're right and  I understand opening new window from desktop
 starts new process, but this is happening after visitor hits the link
 detail view and that is confusing :(

WILD GUESS ALERT!

Perhaps the MS version of open popup in new tab/window is to start a
whole new process?

 This has baffled me all day on my FC6 php-5.1.6 based server.

 On a normal working page, I set a session variable at the top and
 another session variable in the middle of the page/script.  This page
 has no errors nor missing links.  So everything works great.

 Now, if I cause at least 1 image in the page to become missing on the
 server (ie, by deleting a .jpg file), then Apache logs the error as
 usual, ie: File does not exist.  But in addition, my two session
 variables seem to get deleted.  If I put the picture(s) back, then no
 apache errors, and my session vars are set fine.

 I've even enabled detailed php error reporting and I get no errors.

 Is this normal session behavior?  Please say no.  Any ideas?  I can't
 understand why missing links would cause a session variable's
 annihilation.

It's not normal.

Perhaps you have some kind of 404 error handler that is destroying the
session.

 I suspect I already know part of the answer to this, but I'm not sure
 which way to go with it. I've got a project I'm working on and one of
 the things it's got to do is set cookies and then read them later.
 When
 the app was first written I was doing everything in PERL and cookies
 are
 fairly straight-forward, however I'm finding cookies in PHP somewhat
 problematic.

 Setting the cookie is a snap, however getting the info back out is,
 well... problematic.

 this is basically what I'm doing, what I'm seeing in the cookie, and
 what I'm getting back out.

 Setting the cookie
 ==
 $values = blah|blah|blah;
 setcookie(cookiename, $values, time()+$timevalue);

Because IE engineers CANNOT READ a technical document to save their
lives, you MUST supply a path if you supply a time:

setcookie(cookiename, $values, time() + $timevalue, /);

You also don't tell use what $timevalue is, so that could be something
very wrong... :-)

 Inside the Cookie
 ==
 Content: blah%7Cblah%7Cblah


 Getting info Out Of Cookie
 ==
 list($first,$second,$third) = explode(|, $values);

Unless you have register_globals set to ON (bad!) then $values will
only have meaning in the setcookie script...

 Cookie Test Page
 ==
 if (isset($_COOKIE[cookiename])){
   list($first,$second,$third) = explode('|',$_COOKIE[cookiename]);
   echo pI found your cookie/p\n;
   echo pThe following Values were Contained in the cookie:BR
 Username: $firstBR
 Password: $secondBR
 Type: $third/p\n;

You should NOT NOT NOT NOT NOT be storing a username *or* password in
a cookie!!!

 }
 else{
   echo pI wasn't able to find your cookie./p\n;
 }

 Now, I've constructed a cookie_test.php page to check things out and
 the
 strange behavior I'm seeing is, upon first execution I get the else
 block, but if I hit the browser's reload button I get the if block.
 At
 first I thought the cookie wasn't being read at all because of weird
 characters, but then upon reloading the page and seeing the if block
 being displayed I'm thoroughly confused. It's gotta something simple
 I'm
 missing.

What *is* in your cookies?

var_dump($_COOKIES);

Perhaps putting '|' in there is not a valid character?

You could base64 encode it or ...

 and I swear if someone tells me to RTFM I'm gonna shit and go blind
 cause I haven't got a clue as to which part of the FM to read
 concerning this. :)

It would be some chunk of the Netscape Cookie spec.

Google for Netscape Cookie spec and read that.  It's only a page.

  Um... Cookie data ISN'T available to the same script that sets it. If
  you use setcookie(), all it does is send a header to the browser
  immediately ahead of the output of your script telling the browser to
  store those values in either memory or on disk. The value will not
  appear in the $_COOKIE array until the browser requests the next page
  and includes the Cookie: header as part of the request.

You're correct. I was saying basically the same thing, but
re-reading it, it sure doesn't look like it in English.  ;-P

The sentences should've instead been rewritten like so:
Try setting it with one page and forcing a link-click or

 actually opens a new,

  share any persistent cookies with the first, since

Re: [PHP] Cookie Trouble: getting the information back out...

Sessions are only good on the same server as which they were set.
This is because the server writes the data to a file on its side, then
sends just a session ID cookie to the browser.  This session ID holds
no information except the key to the session file on the server with
which it's associated.

However, if you're still on the same server, make sure that you've
used session_start() at the top of every page to which you want the
session to carry over.

EXAMPLE:

Page1session_start() is used and the UID of the visitor is set.
Page 2   session_start() is used, but no data is read/written.
Page 3   session_start() is NOT used, no $_SESSION data available.
Page 4   session_start() is used, and is re-initialized despite missing Page 3.

 Go through all the elements of the object and do some encoding and get

 In raw terms I need to know the procedure that does this and still
 keep the same structure of the array.

[recordingType] = utf8_decode(0)
   [duration] = utf8_decode(3218)
   )


first of all, SimpleXMLElement is not an array, its a class.  It does
support iteration via the foreach construct though.  the foreach iteration
will only go through the first set of elements in the structure, that is it
will only cover the children of the root element.  if you want to traverse
all elements of the structure recursively, use SimpleXMLIterator (and
RecursiveIteratorIterator) from SPL.

heres a simple xample to get you started:

?php
$xml = 'mab//ac//m';
$m = new SimpleXMLElement($xml);
foreach($m as $k = $v) { echo k:$k = v:$v . PHP_EOL; }
/* outputs
k:a = v:
k:c = v:
*/
$m = new SimpleXMLIterator($xml);
foreach(new RecursiveIteratorIterator($m,
RecursiveIteratorIterator::CHILD_FIRST) as $k = $v) { echo k:$k = v:$v .
PHP_EOL; }
/* outputs
k:b = v:
k:a = v:
k:c = v:

You can use onload and XmlHttpRequest to send back the desktop client

Note that you'll need to test on [a] computer[s] where you know the

General rule of thumb used to be 2 seconds...  If your page hasn't outputted 
some form of usable information in 2 seconds or less, people don't stick around.

What's worse is that some browsers require the whole page contents before they 
will draw the page, so you get a white page while the page is loading into the 
browser and the client gets nothing.

Firebug/Yslow are both good extensions to load for Firefox to see where the 
bottlenecks are.

I'd like to do a quick validity check on the email address they just inputted. I can check the

You are really asking an HTML question, if you think about it.

At the PHP level, either use output buffering or assemble all your html string as a variable and 
then echo it.  The goal is to compress the string into the minimum number of packets.

[PHP] date CDT CST UTC

Today, we are in Central Daylight Time CDT in Dallas, Texas, USA -- yes?

date on:
mail server: Wed Mar 26 11:45:00 CDT 2008 (CORRECT)
web server: Wed Mar 26 11:45:00 CST 2008
Note CDT versus CST.

date -u
mail server: Wed Mar 26 16:45:00 UTC 2008 (CORRECT at 11:45 AM local
time [Central Daylight Time (CDT) is UTC minus 5 hours])
web server: Wed Mar 26 17:45:00 UTC 2008

From a test CLI script and from the web page test script on the web server,
echo date(Y-m-d H:i:s);
returns 2008-03-26 11:45:00.

An application PHP script ran on the web server, uses date(Y-m-d
H:i:s) to generate a timestamp to put in the body of an email sent
with PHP mail().
I think the mail() command on the web server forwards to the actual
mail server (but I am not sure -- how do I verify this?).

An example email (only after we switched to daylight savings time on
3/10 and I'm sure our admin had to manually update the clock) shows
the email header as Mon, 10 Mar 2008 14:35:44 -0500
and in the email client without looking at raw source as Date: March
10, 2008 2:35:44 PM CDT, but the body of the email (which used PHP
date(Y-m-d H:i:s)) shows 2008-03-10 13:35:44.
Note 13 instead of 14.

I've asked the admin to make sure the web server reports CDT (I'm
still waiting), but it seems strange that date(Y-m-d H:i:s) from the
test scripts already shows the correct info before this change.

Any thoughts?

Just because it doesn't bounce doesn't mean it's a valid email address.

Because too many sysadmins were NOT updating their time zone database
with package/software updates as they should, the PHP Dev Team got
tired of bug reports et al about messed up dates, and they now include
a CURRENT copy of the timezone database built-in to PHP.

This, of course, violates the principle of having the source in one
place...

But it saves them a lot of headaches.

So PHP knows about the recent date-change of when daylight savings
kicks in, but since your sysadmin didn't update the time zone db on
the web server the OS does *not* know the correct time.

Daylight Savings Time must die!

Really, there cannot be any real savings here... The time wasted by
humanity to reset clocks and fix all the buglets from this stupid
clock-changing game MUST outweight any debatable benefits

There may be a SMTP class to help you do it, or you can do it manually
but here is a quick process.  Look up the MX for thedomain.com. maybe
use  checkdnsrr(). If not found then it is bad, if found connect and
issue the following SMTP commands:

MAIL FROM: [EMAIL PROTECTED]
250 ok
RCPT TO: [EMAIL PROTECTED]
550 sorry, no mailbox here by that name. (#5.7.17)

Optimally you want to see:
250 ok

You could also see:
553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)

This would mean that there is an MX record for thedomain.com pointing to
this server but this server isn't configured to accept mail for this domain.

just deal with this separately.


Is there a better way than simply sending a test email to see if it 
bounces?


Thanks

 Hi
 
 LAMP
 
 A column in a table has Brbeuf  in it. (3rd caracter is eacute;)
 
 I use that table to send emails.
 
 In the body that column shows  Brébeuf  in Windows Outlook.
 
 How could I translate to the correct encoding so that accents show correctly 
 in Outlook ?

based on the encoding of your e-mail, my guess is that your data is in
some ISO-8859-1 encoding or something like that. of course, you should
verify that first.
so try to send those emails with that encoding, or what's much better,
use utf8 for both your data and your email. I think outlook can cope
with that, though I'm not sure ;)

Hi Zoltan,

The encoding can be set to utf-8 in the recieved email, what translates the 
encoding but the sender's outlook window doesn't.

It's a site where you can ask the owner to upgrade your account limit by 
clicking on a mailto link who writes most of the email body. The data used 
is your record from a Mysql table.

When you use that link it opens a email window and the body of that message 
isn't translated. So the people will see some garbage and may not send the 
email.

If I try to change the encoding in the editing window of Outlook while this 
garbaged email shows it doesn't work. I still see the garbage, yet my 
outlook is set for utf-8 !!

[PHP] APC FastCGI != upload progress ?

2008-03-26 Thread steve
We can get upload progress to work with the APC extension for PHP
5.2.x only on machines that are not using FastCGI. (Apache2.2 if it
matters).

 Does anyone have a suggestion where to look?

 Will it even be possible?

 Thanks in advance,

Re: [PHP] Re: optimilize web page loading

2008-03-26 Thread Al
Depends on the server and it's load.  I've strung together some rather large html strings and they 
aways take far less time than the transient time on the internet. I used to use OB extensively until 
one day I took the time to measure the difference. I don't recall the numbers; but, I do recall it 
was not worth the slight extra trouble to use OB.


Now, I simple assemble by html strings with $report .= foo; And then echo $report at the end. It 
also makes the code very easy to read and follow.

 At the PHP level, either use output buffering or assemble all your html string 
as a variable and
 then echo it.  The goal is to compress the string into the minimum number of 
packets.


Yes, but do so smartly. Excessive string concatenation can slow things
down as well. On most pages you probably won't notice much difference,
but I have seen instances where the difference was painfully obvious.

You may want to try this E-mail validation PHP class that does just
that. It simulates an attempt to send a message to the SMTP server of
the e-mail domain. It does not finish to send the message. The message
could still bounce later, but at least you will still detect some
invalid addresses.

You should not send 8 bit data in your messages without proper quoted
printable encoding. Also you need to specify the character set of text
you are sending.

You may want to try this MIME message composing and sending class that
supports quoted printable encoding with any character set either in the
text and in the message body.

Take a look test_email_message.php for single by character sets or even
the test_multibyte_message.php if you are not using multibyte character
sets.

I built a work around.  It requires you to run a PHP daemon.  It handles 
the uploads and passes the information off how ever you want.  To a DB, 
to the filesystem.  Your choice.  From that information, you can create 
a progress meter.


I haven't fleshed out all the bugs, but it seems to work like I want it 
too at least.
