Pasting exactly that into my development server here and calling it from another page didn't throw an error. Perhaps that is not exactly what you have on your site?

Thank you, I'm glad I'm not the only one who's got it running with no problems here.

I am using TextWrangler on a Mac, and have no upgrades on my account...

The point I am making is that the code you showed works for me, but the code you have on your website doesn't work. Therefore, there is a difference.

Well as far as I'm aware that line isn't all that important anyway, so try this:

Code:

<?php
function ismobile(){
  // check if the user agent gives away any tell tale signs it's a mobile browser
  if(eregi('up.browser|up.link|windows ce|iemobile|mini|mmp|symbian|midp|wap|phone|pocket|mobile|pda|psp|N70|S60|S40|S80|S90',$_SERVER['HTTP_USER_AGENT'])){
    return true;
  }
  // check the http accept header to see if wap.wml or wap.xhtml support is claimed
  if(stristr($_SERVER['HTTP_ACCEPT'],'text/vnd.wap.wml')||stristr($_SERVER['HTTP_ACCEPT'],'application/vnd.wap.xhtml+xml')){
    return true;
  }
  // check if there are any tell tales signs it's a mobile device from the _server headers
  if(isset($_SERVER['HTTP_X_WAP_PROFILE'])||isset($_SERVER['HTTP_PROFILE'])||isset($_SERVER['X-OperaMini-Features'])||isset($_SERVER['UA-pixels'])){
    return true;

The point I am making is that the code you showed works for me, but the code you have on your website doesn't work. Therefore, there is a difference.

(S)He had me take a look at the code on the server, I couldn't see anything wrong, but I uploaded a copy of the working code from my test server and it's working now.  So this should be considered resolved until (s)he tests the code with either a mobile browser or a user-agent faker.

I'm a he(michael, and pic of me on website) but I think that the app that I use to make the php file doesn't like php files, and i have faked the user agent to be an iphone, and it doesn't work I can't really tell why because it switches to fast


Okay I say this topic is over because I give up.  I cannot make php files that will work but for future reference if you can make php files that work, this solution stated in the post above work...

You should change this code on your page

<?php echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"; ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<?php
require_once "ismobile.php";
if (ismobile() == true) {
header("location: http://michaellindahl.com/m/");
 exit;
}
?>

to this

<?php
ob_start();
echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"; ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<?php
require_once "ismobile.php";
if (ismobile() == true) {
header("location: http://michaellindahl.com/m/");
 exit;
}
?>

what i added is the ob_Start() since header(); will not work if you already sent a data to the browser that is the

Code:

echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";

in your code it is also better if you write it this way if you dont want to add the ob_Start() in your code

<?php
require_once "ismobile.php";
if (ismobile() == true)
{
 header("location: http://michaellindahl.com/m/");
 exit;
}
?>
<?php echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"; ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

make sure also that there are no whitespaces before the first character of your script...

I have a feeling that the program you are using is not the right program for writing PHP files, it is probably adding certain things you do not want, when you save the file

Yea my program, TextWrangler on the Mac, works fine with HTML but when I changed it to .php it might have an issue with that...
