移动或桌面浏览器检测和重定向到各自的网页

你可以使用。htaccess在这个答案或这个答案中或者你可以在php中检查user-agent:

<?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');
?>

代码来自detectmobilebrowser.com

Mobile Detect是一个轻量级的PHP类，用于检测移动设备(包括平板电脑)。它使用User-Agent字符串结合特定的HTTP报头来检测移动环境。在进一步操作之前，请注意，"移动检测"类是一个服务器端(PHP)检测工具，它不能替代响应式网页设计(媒体查询)或任何其他形式的客户端功能检测。

将站点重定向到移动版本

/* 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;
}

如果从手机上查看，上面的代码现在会将主站点重定向到移动版本。下面给出了一些重定向的其他用例。

// 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()) {
}

根据设备加载不同的资源

$detect = new Mobile_Detect;
if($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' />";
}

使用相同的命令，但设备更少:

<?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>"; } ?>

感谢这个代码片段，只是有一个类似的需要，在Chrome, FF和IE之间的差异不堆叠，一个简单的ccs编码不再做这项工作，所以一个专门的HTML页面必须创建不仅为浏览器，但显示尺寸，以覆盖4:3 16:9比例的屏幕…

无论如何，使用您的示例，我已经开发了php来提供浏览器类型，构建和屏幕分辨率的反馈。

希望你找到这个使用的适应，如果有人改进它，欢迎改进，因为只花了1小时，所以还没有机会为许多浏览器类型指定所有选项-所以目前只开发完全为Chrome, IE和FF
