I'm building a website in PHP which contains flash in its index page. I want to redirect users who are accessing my site via any mobile browser to page m.index.php which doesn't contain flash(simple page) for loading purposes. For others who access via desktop browser to index.php which contains flash in it.
How can I redirect each user based on their platform?
You could use .htaccess like in this answer or in this answer or you could check the user-agent in php:
<?php
$useragent=$_SERVER['HTTP_USER_AGENT'];
if(preg_match('/android|avantgo|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(hone|od)|iris|kindle|lge |maemo|midp|mmp|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)\/|plucker|pocket|psp|symbian|treo|up\.(browser|link)|vodafone|wap|windows (ce|phone)|xda|xiino/i',$useragent)||preg_match('/1207|6310|6590|3gso|4thp|50[1-6]i|770s|802s|a wa|abac|ac(er|oo|s\-)|ai(ko|rn)|al(av|ca|co)|amoi|an(ex|ny|yw)|aptu|ar(ch|go)|as(te|us)|attw|au(di|\-m|r |s )|avan|be(ck|ll|nq)|bi(lb|rd)|bl(ac|az)|br(e|v)w|bumb|bw\-(n|u)|c55\/|capi|ccwa|cdm\-|cell|chtm|cldc|cmd\-|co(mp|nd)|craw|da(it|ll|ng)|dbte|dc\-s|devi|dica|dmob|do(c|p)o|ds(12|\-d)|el(49|ai)|em(l2|ul)|er(ic|k0)|esl8|ez([4-7]0|os|wa|ze)|fetc|fly(\-|_)|g1 u|g560|gene|gf\-5|g\-mo|go(\.w|od)|gr(ad|un)|haie|hcit|hd\-(m|p|t)|hei\-|hi(pt|ta)|hp( i|ip)|hs\-c|ht(c(\-| |_|a|g|p|s|t)|tp)|hu(aw|tc)|i\-(20|go|ma)|i230|iac( |\-|\/)|ibro|idea|ig01|ikom|im1k|inno|ipaq|iris|ja(t|v)a|jbro|jemu|jigs|kddi|keji|kgt( |\/)|klon|kpt |kwc\-|kyo(c|k)|le(no|xi)|lg( g|\/(k|l|u)|50|54|e\-|e\/|\-[a-w])|libw|lynx|m1\-w|m3ga|m50\/|ma(te|ui|xo)|mc(01|21|ca)|m\-cr|me(di|rc|ri)|mi(o8|oa|ts)|mmef|mo(01|02|bi|de|do|t(\-| |o|v)|zz)|mt(50|p1|v )|mwbp|mywa|n10[0-2]|n20[2-3]|n30(0|2)|n50(0|2|5)|n7(0(0|1)|10)|ne((c|m)\-|on|tf|wf|wg|wt)|nok(6|i)|nzph|o2im|op(ti|wv)|oran|owg1|p800|pan(a|d|t)|pdxg|pg(13|\-([1-8]|c))|phil|pire|pl(ay|uc)|pn\-2|po(ck|rt|se)|prox|psio|pt\-g|qa\-a|qc(07|12|21|32|60|\-[2-7]|i\-)|qtek|r380|r600|raks|rim9|ro(ve|zo)|s55\/|sa(ge|ma|mm|ms|ny|va)|sc(01|h\-|oo|p\-)|sdk\/|se(c(\-|0|1)|47|mc|nd|ri)|sgh\-|shar|sie(\-|m)|sk\-0|sl(45|id)|sm(al|ar|b3|it|t5)|so(ft|ny)|sp(01|h\-|v\-|v )|sy(01|mb)|t2(18|50)|t6(00|10|18)|ta(gt|lk)|tcl\-|tdg\-|tel(i|m)|tim\-|t\-mo|to(pl|sh)|ts(70|m\-|m3|m5)|tx\-9|up(\.b|g1|si)|utst|v400|v750|veri|vi(rg|te)|vk(40|5[0-3]|\-v)|vm40|voda|vulc|vx(52|53|60|61|70|80|81|83|85|98)|w3c(\-| )|webc|whit|wi(g |nc|nw)|wmlb|wonu|x700|xda(\-|2|g)|yas\-|your|zeto|zte\-/i',substr($useragent,0,4)))
header('Location: http://detectmobilebrowser.com/mobile');
?>
Code from detectmobilebrowser.com
Mobile Detect is a lightweight PHP class for detecting mobile devices (including tablets). It uses the User-Agent string combined with specific HTTP headers to detect the mobile environment. Before procedding further, note that, ‘Mobile Detect’ class is a server-side (PHP) detection tool, it is not a replacement for Responsive Web Design (media queries) or any other form of client-side feature detection.
Redirecting a site to a mobile version
/* Change path info depending on your file locations */
require_once 'Mobile_Detect.php';
$detect = new Mobile_Detect;
if($detect->isMobile())
{
header('Location: http://mobile.example1.com/');
exit;
}
The above code will now redirect the main site to a mobile version if viewed from a mobile. Some other use cases to redirect are given below.
// Any tablet device.
if( $detect->isTablet()) {
}
// Exclude tablets.
if( $detect->isMobile() && !$detect->isTablet()) {
}
// Check for a specific platform with the help of the magic methods:
if( $detect->isiOS()) {
}
if( $detect->isAndroidOS()) {
}
if( $detect->isWindowsPhoneOS()) {
}
Loading different resources depending on the device
$detect = new Mobile_Detect;
if($detect->isMobile() || $detect->isTablet()) {
echo "<link rel='stylesheet' href='mobile.css type='text/css' />";
} else {
echo "<link rel='stylesheet' href='style.css type='text/css' />";
}
This uses the same command but just less devices:
<?php $iphone = strpos($_SERVER['HTTP_USER_AGENT'],"iPhone"); $android
= strpos($_SERVER['HTTP_USER_AGENT'],"Android"); $palmpre = strpos($_SERVER['HTTP_USER_AGENT'],"webOS"); $berry = strpos($_SERVER['HTTP_USER_AGENT'],"BlackBerry"); $ipod = strpos($_SERVER['HTTP_USER_AGENT'],"iPod");
if ($iphone || $android || $palmpre || $ipod || $berry == true) {
echo "<script>window.location='http://mblistings.com/mob/index.php'</script>"; } ?>
Thanks for this code snippet, just had a similar need where the differences between Chrome, FF and IE do't stack up, and a simple ccs coding doesn't do the job anymore, so a dedicated HTML page has had to be created for not only Browser, but display sizes so as to cover 4:3 16:9 ratio screens...
Anyway, using your example, I have developed the php to provide feedback for browser type, build and screen resolution.
Hope you find this adaptation of use, if anyone improves on it, welcome the improvements as only spent 1hr on this so haven't had the opportunity to specify all the options for the many browser types - so currently is only developed fully for Chrome, IE and FF
