I suppose that resizing could be viewed as one of those 80/20 percent rule things.. meaning, window resizing is probably not a prevalent action for a user and it could be argued that one shouldn't code a site worrying too much about dynamic window resizing... but then there is a form of resizing, which is turning your iPAD to landscape view, etc.. I suppose one could probably still do some UA detection and serve up content based on the type of UA (ie. mobile, IE, game-based) and at that point, still incorporate responsive web design, but to that more-limited-category of UA's. Donovan -- D Brooke There is only one drawback to using CSS media queries to alter the way a page is displayed on different resolutions, and that is that any media (i.e. background images, etc) referenced in a stylesheet is downloaded, regardless of if it is ever used. 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

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.

Re: [PHP] Headers on smart phone browsers
1) Do smart phones use the same browsers as the desktop, or do they have their own stripped down versions of browsers? Different browsers, some of which are worse than IE (see Blackberry). 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? Nothing so specific or easy to identify as i am a smartphone. Depending on your target audience, simple regex checks for the strings iphone, android, etc. can do the trick, but if you want specific details about the device... 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)? ... the WURFL database and things akin to it or based on / stolen from it can help parse the header string and return a plethora of information about it (screen size, AJAX ability, markup capacity, etc).

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.

Re: [PHP] Headers on smart phone browsers
Mari Masuda wrote: [snip] For a concrete example of responsive design in action, point your browser to http://www.sasquatchfestival.com/ and then slowly make the window wider/skinnier to see how the design adapts to different viewport sizes. Very nice... makes for an easy display to a wide range of circumstances I think.. especially image resizing (in the blog example), which looks pretty smooth. But, in both the examples, it appears it can produce a choppy user experience when resizing the window as well... I suppose that resizing could be viewed as one of those 80/20 percent rule things.. meaning, window resizing is probably not a prevalent action for a user and it could be argued that one shouldn't code a site worrying too much about dynamic window resizing... but then there is a form of resizing, which is turning your iPAD to landscape view, etc.. I suppose one could probably still do some UA detection and serve up content based on the type of UA (ie. mobile, IE, game-based) and at that point, still incorporate responsive web design, but to that more-limited-category of UA's.

[PHP] Headers on smart phone browsers
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)?

[PHP] headers help
Hello all, I must confess I know the very basics on this language and have even less knowledge about http headers. I wish you could help me out on this: I have a form that sends html e-mails and an optional file as attachment. The issue is that, if the file is NOT send, the e-mail receives two times the same content, one that gets read by the mail clients as HTML properly, and, a literal print of my $message string variable that contains: html head /head boby tableMy form contents/table /body /html I believe that the reason for this lies on the $header options, probably on line number 8 ? Here is the, what I believe, is the relevant code: http://pastebin.com/5ywdK0UU What should I do, to avoid this extra html code on the e-mail messages ? Thanks in advance, Márcio
[PHP] headers: setting right for browser to force reload at a certain point in time
Hi All, We have an application that generates dynamic ebooks. One of the (minor) problems (but yet annoying) is that when a user comes back to an ebook, they have to actually delete the cache and reload the page to not get the cached version which might be wrong because the content or even the flash application is updated. It would be neat if we could force a reload of the page, but only with a special condition like the ebook being updated or the swf. The swf and also the other resources are not reloaded though, because it is a get request. Is there a way to force a reload of the browser by maybe changing the headers? Or do we have to do some fancy stuff like storing a cookie with the time and sending it back via ajax or something like that? Just setting the header would be nice... Maybe the easiest would be to change the link (add a number or something) of the html page and have a rewrite for all the relative urls as well.

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.

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!

[PHP] headers and session
Does config.inc.php have any whitespace following the closing ? tag, or does it output any HTML? That could be your culprit. What happens if you do your $_SESSION setting *before* the require, but directly after the initial header() call? He knew that header may give problems with whitespaces, but this was not the case. With regard to your secondo question, it works ! that is, the code now looks like: ?php session_start(); $_SESSION['session_psw'] = $_POST['txtPassword']; $_SESSION['session_user'] = $_POST['txtIdUtente']; header( Cache-control: private ); require_once(config.inc.php); $PHPcmd = $GLOBALS['gestionale_path_name'].test/2.php ; header( Location: .$PHPcmd ); ?

[PHP] headers and session (2)
I want to thank you all for previous helpings.
Really the first code was easy to be solved, but
this is how it shall work out. This is a program running
locally and the trouble is that session vars are stored
in local files. I must avoid to store a plain text password
therein, thus I need to crypt and save it into session.
When 2.php file just displays session data (it is test environemnt),
but the output is blank !
Suggest a different approach ?

session_start();
require_once('crypting.php');

RE: [PHP] Headers Again
Got to agree with Jason's comments - as I'm sure all other regulars on the list will do. I've just had a quick look at the php.net site, done a search for header and halfway down the first page returned found this: Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP. It is a very common error to read code with include(), or require(), functions, or another file access function, and have spaces or empty lines that are output before header() is called. The same problem exists when using a single PHP/HTML file. Not hard is it?

[PHP] Headers and sessions in php .cgi
Hi there,
I have a problem setting my headers right with php running as .cgi. I
have to specify a Content-type for the cgi file to work. But how
should I do both that and start a session?
I have a few options:
#! /usr/local/bin/php
?php
session_start();
print 'Content-type: text/html' . \n\n;
This way $_SESSION['count'] stays unset even though I say
$_SESSION['count'] = 1; in my program.
To swap the two lines won't work because I heard \n\n terminates the
header portion. Anyway, here goes:
#! /usr/local/bin/php
?php
print 'Content-type: text/html' . \n\n;
session_start();
Now I get Warning: session_start(): Cannot send session cookie -
headers already sent by... line 3 and then Warning: session_start():
Cannot send session cache limiter - headers already sent
I have tried replacing print 'Content-type: text/html' . \n\n; by
print 'Content-type: text/html' . \n; (one \n instead of two) with
exactly the same result. With no \n at all I only get Warning:
session_start(): Cannot send session cache limiter - headers already
sent.
The next thing I try is to replace print 'Content-type: text/html' and
the \n's by sending the same text in header(). This variety gives me a
500 Internal Server Error independant on the number of \n's.
Anyway, here's all my code. No matter what I do it always prints Your
visit number 1. $_SESSION['count'] doesn't get increased at all!
#! /usr/local/bin/php
?php
print 'Content-type: text/html' . \n\n;
session_start();
print 'html' . \n;
print 'body' . \n;
if (!isset($_SESSION['count']))
{
$_SESSION['count'] = 1;
}
else
{
$_SESSION['count']++;
}
print 'Your visit number ' . $_SESSION['count'] . \n;
print '/body' . \n;
print '/html' . \n;
?
I hope you can help me out getting my headers straight.
Regards,
Børge

Try using header() instead of print to set Content-Type. Hope that helps. 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.

Re: [PHP] Headers Sent Message
From: Mark Roberts [EMAIL PROTECTED] Could someone help me out with this. I had this problem about a year ago with another site and I can't for the life of me remember what I had to do to fix it. I am in a oscommerce application, however I think it is really a php problem. I get this message when ever I try to update the admin portion of the site: Warning: Cannot modify header information - headers already sent by (output started at /home/virtual/site1/fst/var/www/html/admin3/includes/application_top.php:267 ) in /home/virtual/site1/fst/var/www/html/admin3/includes/functions/general.php on line 18 I always get yelled at for answering these questions and doing the whole take my hand and follow along as we read this together... but oh well... output started at .../application_top.php:267 means that application_top.php has output on line 267. You cannot send any header information (header(), setcookie(), session_start(), etc) after there is output. general.php is trying to send header information on line 18, after application_top.php has been included and already caused output. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Something is being output there, or perhaps there is something on that line that generates an error. In this script: general.php You are doing something that outputs a header on line 18, and the output from application_top.php happens prior to this, which cannot happen. Hope that helps.

The errors you report are only the last one, the first and main problem is that this line failed: include(DIR_WS_CLASSES . 'language.php'); // application_top.php:267 It generated a warning and the headers and then the html body was send. Basicly your main language file is missing.

[PHP] Headers, outputting a file ..
Hi All, I feel almost ashamed for having to ask this question. Mostlly because I know it's been asked so many tmes but I just don't seem to be able to get it working. I want to secure some files from viewing by putting them in a different folder than the document root. Then, through a simple Content class output them to the browser, and of course have this browser display the page correctly. This file comes from an admin user upload, and can be of any time. pdf, doc, jpg, xls, well .. don't need to name all existing file extensions, do I? And I just know the answer has been given in a previous post, which I just cannot find on the archives. Here's the deal: 110 $File = $this-Get($User); 111 112 foreach($File['Headers'] as $H) header($H);; 113 readfile($File['Path']); Which I think is perfectly valid code for outputting this file. Now, several examples of what $File will contain after the call to $this-Get($User) ;) 1: Array ( [Headers] = Array ( [0] = Content-Type: image/pjpeg [1] = Content-Disposition: attachment; filename=duuude.jpg [2] = Accept-Ranges: bytes [3] = Conent-Length: 23256 ) [Path] = /home/wouter/projects/mspa.nl/files/duuude.jpg ) 1: Array ( [Headers] = Array ( [0] = Content-Type: application/msword [1] = Content-Disposition: attachment; filename=Modulehandleiding.doc [2] = Accept-Ranges: bytes [3] = Conent-Length: 156672 ) [Path] = /home/wouter/projects/mspa.nl/files/Modulehandleiding.doc ) 1: Array ( [Headers] = Array ( [0] = Content-Type: application/pdf [1] = Content-Disposition: attachment; filename=Interviewschema.pdf [2] = Accept-Ranges: bytes [3] = Conent-Length: 40141 ) [Path] = /home/wouter/projects/mspa.nl/files/Interviewschema.pdf ) As for the first one, it works. It shows me the image on my screen .. The word document and pdf file are shown as they would look like if they're opened in notepad or such. Any help is widely appriciated .. ;) Wouter Ps. To clearify: $this is the internal instance of my Content class, $User is passed onto the function to check if he is allowed to view the content. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
