Not only the size of the display -- but what's a size of a pixel? http://www.alistapart.com/articles/a-pixel-identity-crisis/ Presentation is a difficult problem to solve, but I don't think PHP enters into the equation. From my view, the only thing that PHP can do is device-sniff, which is clearly a losing proposition. I believe that a presentation solution will be solved by presentation languages (i.e, client-side).

Another one worth mentionning is that a lot of mobile devices still in use do not support media queries - their being a relatively recent development. Same goes for javascript, even if it claims to support it. Older Blackberrys claim JS support but fail miserably in real life.

So if you have two background images for the body, one large for nice wide screens, and a smaller one for smaller screens, they will both be downloaded by the browser. The way around this is to use Javascript to load only the stylesheets required, but then you're relying on Javascript and you don't need media queries. It's a pain finding the right balance. -- Thanks, Ash http://www.ashleysheridan.co.uk

Logical, but I can save you that step :-) as I've been there done that..
Here is a PHP script (uses $_SESSION) for mobile users that I have found
to work fairly well. I'm absolutely sure that it contains false
positives, and potentially other minor bugs.. as it's just hard to keep
up with the ever changing UA's... but it's a start.
If it gets munged from email returns, I can zip it up.

The issue with this (according to the get_browser() docs) is that the browsecap file is 300K long, will get longer, and significantly slows loading of your applications. Moreover, the parsing of the UA string and other data is far more extensive than anything I'd want or could use. The only thing I'd want to know is whether I'm serving pages to a handheld or desktop device. >From what I've seen, pages built for handheld devices (see, for example, yahoo.mobi) are considerably stripped down, often with no CSS styling. For now, if I have to make the decision on whether to serve up desktop or handheld versions of a page, all I want to know is a yes or no answer to the question of, "Is this a handheld?" The native PHP get_browser() function appears to be overkill for that, and may, in fact be insufficient. That was the origin of the original questions-- was there some definitive way of knowing the platform when the page request came in. And from all the research I've done, the answer is, "No". The UA string may not work as intended. There are javascript sniffers and CSS triggers, but neither are they definitive. For example, the CSS triggers test for resolution or screen width or the like. This is fine, so long as handhelds remain at crappy resolutions. But I don't expect that to be the case forever. Paul -- Paul M.

Multiply that by versions of same, different OSes on which each run, versions of the OSes themselves, etc. etc. etc. I don't envy the job of any piece of code which tries to analyze all this.

Generally speaking you're better off with a design that automatically adapts to the viewport on which it's being displayed. While there's more than one reason for this, the overriding reason is that the same software (i.e. the same user agent) could be running on any size of device, from watch to huge flat panel screen on a wall. I think the world needs to move on from "is it a mobile device or not" to accepting the reality which is that the browser / OS is irrelevant, and that the way your site renders should be purely based upon the size of the display.

Basically, you can use that to read in the raw user agent string from the browser, and it then finds a matching entry in the ini file and gives you back some values about what it can assume about that device, such as whether it is known to support Java (although this is something you should be careful of, as it only tells you if it's is supported, not if there is an available JVM), if it is a mobile or search bot, what version of CSS it should support, etc. I use it myself in a personal web stats script, and as long as you keep the copy of the ini file recent, you should be OK. -- Thanks, Ash http://www.ashleysheridan.co.uk

Paul M Foster wrote: This is sort of obliquely related to PHP. I don't have a smart phone, but I need to know a couple of things: 1) Do smart phones use the same browsers as the desktop, or do they have their own stripped down versions of browsers? 2) When a browser broadcasts its header telling the server what kind of browser is involved, do they broadcast anything in the header to indicate that they're being run on a smart phone? 3) Bonus question: Is there a preferred method amongst coders to determine what type of environment is being browsed from, so as to serve up the proper type of page (desktop or smart phone version of a webpage)? Paul Hi Paul, I think this is a great PHP conversation.. and I don't understand why GOTO threads always get way more replies than something like this ;-) Diverse User Agent compatibility is going to be more and more of a challenge for us.. gone are the days of a few known browsers that are viewing our sites. From bots, to browsers, to mobile devices, to game UA's, to app UA's.., to IE's stubborn outlook on the web... the idea of user experience is growing complicated! ;-) I really liked Mari's posted link to the "a list apart" blog about "responsive web design" using "media query" (CSS).. however, it seems to me that it takes the use of many languages and techniques in many cases to get the job done... user agent serving (using PHP or JS or alike), flexible CSS and web design, and a keen eye on your target audience may all play apart. However, this is a PHP list.. and I think we can better approach this topic by limiting our scope to talk about how PHP could be useful. My first question, being that my first language is not PHP, is; is their any core PHP mobile detection functions/tools that exist? I have a running list of mobile UA's that I picked up somewhere that I often use and edit to distribute content accordingly. I also have a PHP mobile detection script that I picked up somewhere. I'm sure these things can be found via google as well. The problem, as Mari's link suggests, is that UA "list's" and browser sniffing scripts need maintaining quite regularly, since mobile UA's are being added on a weekly basis perhaps. Many of my projects do some PC UA (browser) sniffing.. especially for IE., as IE has it's own system that it uses for how to render content. Anyway, I'm happy to share what I have.. but like I said, PHP is not my first language, so I am interested to see what the more established PHP'ers may have to say.

Copy it over how?...
Plus, I gotta tell ya, all those goofy extra headers are simply NOT
doing what you think they are...
First of all, unless you add a ", TRUE" as a second arg, each header()
call with the same "XXX: " start is REPLACING the previous ones.
So you are ALWAYS using Content-type: application/x-msexcel and you
might as well rip the rest of them out.
Some headers can have multiple instances (Cache-control) but you only
get ONE Content-type. Period.
You should also compare the actual bytes of the file you get from the
download with the file you copied over. Did PHP add something or
strip something out? Usually this problem has a self-evident solution
once you identify the problem, so I'll say no more in this vein.
And, finally, if you want to support legacy browsers and all kinds of
"gotchas" with downloads, read this rant:

Re: [PHP] headers already sent.
There is no real way of knowing if output is going to be sent before a
header or not, unless its a very simple page.
Your best bet is to investigate the output buffering functions here:

chris, i'd already asked/explained the error. to reiterate, the error i'm getting is the error that's generated when you try to use the php 'header' function, and it throws a warning/error regarding 'headers already being sent...' the soln appears to be to use the php buffering functions, as this is supposed to stop output from being generated/posted, allowing the app to 'buffer' the output until the page is displayed. i've tried to use an 'ob_start()' as the very 1st line in the index.php page that's being displayed. i've also tried to insert the 'ob_start()' in a number of various places within the app with no change... my question was how/what could i possibly do, short of using the javascript soln, which seems to work... i also stated that i could readily provide the code that i'm creating if anyone wanted to take an actual look. and as i also stated, yeah, it could/should be cleaned up, but for now, it's a test app... -bruce -Original Message- From: Chris Shiflett [mailto:[EMAIL PROTECTED] Sent: Sunday, September 18, 2005 8:20 PM To: [EMAIL PROTECTED] Cc: 'php' Subject: Re: [PHP] headers .vs javascript location.href bruce wrote: > need to talk to someone to figure out how/what i need to do to use > the php 'headers' function, as opposed to the javascript 'location.href'. > > i've tried to implement the buffering functions, but still get the same > error... > > is there someone that i can talk to about this, who ha > experience/understanding of what's going on. i've thought about rewriting > what i have to this point, but i've got code interspersed with html... > > yeah.. i know... cleaning it up would probably make things easier/better, > but this is a quick/dirty test.. and i don't claim to be a web developer!

Rest assured, *something* is getting output before you try that header()
call. Anything outside of PHP tags (carriage rturns/line feeds/spaces)
any echo or print.
To help you figure it out, try doing something like exit('STARTOFBODY');
instead of the header call. Then view the source of the ouput and see
what precedes that

PETCOL wrote: Unfortunately history tells me that php like ColdFusion will one day be bought out by the big corporates, or at least they'll have a considerable financial vested interest in it. Not likely. Since PHP is open source if Zend decided to change the license I'm certain it would be forked and continued as an open source project. This is the basis of why open source software is so popular and also why there is negligible gain to be had by Zend in changing the license. At which time we hope way off in the future, we'll all have to start paying for support and maintenance contracts. EVen if it did happen you'd be in no different a position than you are now. This mailing list is primarily user-supported and would likely continue even if PHP became a commercial product (which it won't - see above). If you want commercial support for PHP you can get it. And you'll pay for it. Allaire owned ColdFusion, the developer network was extremely co-operative, then joint venture between Macromedia and Allaire, now if you want good old assistance you need a "Devnet" contract. ColdFusion was never open source (afaik). That's the difference.

Re: [PHP] Headers Again
Jason, I appreciate people get just as frustrate by reading repetative posts. Alliare and Macromedias forums for ColdFusion and other software, allow a search through the entire post, archive everything. Which always avoid this problem of a newsgroup. Maybe I'm wrong, but I don't thing there's a search like this for a newsgroup? If you do happen to know, as it would appear you may, the url of the answer to the original question, then could you simply supply it. I'm new to this code, I appreciate any assistance, and I will troll through archives etc to get it. However, if some kind sole can save me 3 hours work, I'll also appreciate it, which is probably why this list get repetative posts. Cheers, relax, and have a nice day.

Re: [PHP] Headers Again
Jason,
What I shock, 307,000 entries returned.
Maybe someone with ability greater or other than I, should give some serious
consideration to a solution or work around.
I've been using ColdFuion for 7 years and I can do a anywhere in the page, no matter if I've run CFML,
Javascript it still works.
Sorry I'm just frustrated.

Thanks Chris. I tried that (see original post). Then I get a 500 error in my browser and bad header in error_log. Guess I'll have to take session_start() apart and see what it does. This all worked in 4.2, though, where I used .cgi files without a die-hard need for Content-type. As I said in a previous post, everything works when I run my program as a .php file without Content-type. So I guess there's a conflict between the Content-type header and those inserted by session_start() in 4.3.4.

Well, there's one thing I have found out here and that is that there's
no such thing as a stupid question. I've tried searching for

RE: [PHP] Headers Problem
Yes, there was a blank line. Now I just have to test it to see if that was it. One other question though. It appears that Windows does not have this problem - the site in question is on a Linux box. Why would this be? The two sites are identical, I just use the Windows one for developing and testing. I have looked at both php.ini files, and other than the OS specific stuff, they are the same as well. Thanks again... -Original Message- From: CPT John W.

Hi Mike, hi all,
I solved this nasty one! Happy. Your analysis is totally correct, Mike.
Every visitor who puts an item in cart for the first time will get a
cookie and... receives the error on his screen. And I, ... I didn't have
this error message!
What did it for me was:
so , i just called the function and assigned it to a variable and...
gone with the wind!

Here's the URL:
http://www.aurelis.org/store/cart.txt
and the get_cartID:
http://www.aurelis.org/store/includes/functions/get_cartID.txt
--
I've only had time for a quick look, but I think I have an inkling of
where
your problem might be.
It all seems to lie with the way you've implemented GetCartId() -- and
the
problem will only show up any time the cartId cookie is not already set.
Basically, if the cookie is not set, GetCartId() generates a new ID and
sets
the cookie -- but this requires sending a header, and you can't do this
once
you've started output of the real page. So you must make you first call
to
GetCartId() *before* you send any output. Now, if we look at this
fragment
of code from /store/cart.txt:
function ShowCart($lang)
{
global
$connection,$lang_dir,$DOCUMENT_ROOT,$page_theme,$country_iso_code,$srch
_ter
m;
/* ob_start(); //start buffering output */
$page_title=get_label(194,$lang,$connection);
$page_tab=3;
include_once($DOCUMENT_ROOT . "/header_aurelis.php");
$country_iso_code = $_GET[country_iso_code];
if($lang=="EN"){
$currency_symbol = "$ ";
}
else{
$currency_symbol = "€ ";
}
$totalCost = 0;
$show_cart = @mysql_query(("select * from cart inner join items on
cart.itemId = items.itemId where cart.cookieId = '" . GetCartId() . "'
order
by items.itemName asc"),$connection);
... we can see that you include header_aurelis.php, which presumably
outputs
the initial part of your HTML, before you do
$show_cart = @mysql_query ... ;
which includes a call to GetCartId() -- which will attempt to set the
cartId
cookie if it's not already set, and will fail with the "headers already
sent" error.
So, overall, I'd say you've got to get/set your cartId earlier in the
game
-- and certainly before you call or include anything that outputs actual
page content.
This analysis also explains why the error is intermittent -- someone who
has
set the cartId cookie once will probably not see the error again until
after
the cookie expires 30 days later!
Hope this helps (and you followed my somewhat rambling explanation!)
Cheers!
Mike

RE: [PHP] headers already sent and cookie problem
Thanks for your tips Mike! One nasty thing to debug is that the error only shows up from time to time. So now everything seems OK. What do i have now? I start my code with session_start Then include some files. The last one is get_cartID.php (remember?) Then i use several functions to have cart functionallity. In show_cart i include my page heading and then output further body and footer content. When I put the get_cartID include file AFTER include "heading.php" into my show cart function, the other functions start complaining they can't access the function get_cartID. Lots of text, sorry for that. But I still don't have the clue. Maybe you like to see my code? Any help welcome!

Re: [PHP] headers already sent and cookie problem
You cannot send any page information before you send headers (ie setting a cookie), that means there should be no html before the php that sets the cookie, also any function that are called before you set the cookie cannot output to the browser.

Re: [PHP] Headers in body - what am I doing wrong???
When using my yahoo account as test-target for this script, I get this in return from my Mercury server: == quote from error message == The mail server has encountered errors processing your request: * Unrecognized command "Reply-to:". From: "DeltaPower" <[EMAIL PROTECTED]> Reply-to: "DeltaPower" <[EMAIL PROTECTED]> Obviously, there's an extra line between the From and the Reply-to field, which is why Mercury thinks the reply-to is in the body. Mercury is made (or setup, not sure which) so that it will stop processing when it finds something it doesn't understand. I use the reply to field just as a safety measure ... Any ideas y'all ??? You are already pretty far in determining the problem. Indeed the border between the header and content of a mail is an empty line. What if i just give a hint? Look closely: $from = "\"$name\" <$address>\r\n"; $headers .= "From: ".$from."\r\n"; See ?

Re: [PHP] Headers bust ?
Malcom,
Do your logic test before your input form. When you think of how a script
is processed, on the server, then you'll see that the logic portion must
precede any display portion.
Juli Meloni has a good example of this structure in her custom error
message example. You'll find it at www.thickbook.com
Scripting often requires us to invert what we would see as the "normal"
flow of eventsl

The error messages;

The script;

How can I redirect without output before the header ?

Hi Malcom--
Looks like you are outputting data right after your script starts (on
line to, you have an echo right away). You should either (a) turn on
output buffering, which should take care of the problem, or (b) (the
best solution because it makes your script behave the way it should)
move things around so that the decision on the redirect is made before
outputting anything. Try adding this at the beginning, before the echo:
if ($dog == 'mal')
header ('Location: ../aamaillist/ml_menu.php');
Hope this helps!
Marco

the correct syntax is
header("Location: http://www.yourdomain.com/php/events.php";);

Re: [PHP] headers and cookies
This is not correct. Both the setcookie() and header() functions manipulate the HTTP headers in the response. You cannot have output prior to any function that manipulates headers - that's the limitation. These two functions work fine together in any order; it's prior output that will cause an error.
