现在移动互联网越来越发达,很多的网站都普及了手机端浏览,为了更好的让网页在手机端显示,我们都选择了使用CSS媒体查询制作响应式模版,但这也有弊端,例如某些网站的结构是CMS类型的,太多的内容要显示,而使用CSS媒体查询设计响应式,只会隐藏但还是加载了,为了让手机端更快速的显示出内容,我们可以使用这个PHP判断手机设备代码,使用这个代码可以很方便的显示或不显示自定义的内容。
在做WEB开发的时候经常会需要用到对移动设备的页面匹配,当然可以直接把网站做成响应式的,但如果不想这么做的话,可以使用PHP对设备类型进行判断, 然后显示相应的界面和内容。今天分享一种使用 PHP 判断设备是否是手机/平板的方法,方法来源于WordPress(wp-includes/vars.php:125),适用于大部分类型的手机/平板判 断:
方法一:
/**
* Test if the current browser runs on a mobile device (smart phone, tablet, etc.)
*
* @staticvar bool $is_mobile
*
* @return bool
*/
function wp_is_mobile() {
static $is_mobile = null;
if ( isset( $is_mobile ) ) {
return $is_mobile;
}
if ( empty($_SERVER['HTTP_USER_AGENT']) ) {
$is_mobile = false;
} elseif ( strpos($_SERVER['HTTP_USER_AGENT'], 'Mobile') !== false // many mobile devices (all iPhone, iPad, etc.)
|| strpos($_SERVER['HTTP_USER_AGENT'], 'Android') !== false
|| strpos($_SERVER['HTTP_USER_AGENT'], 'Silk/') !== false
|| strpos($_SERVER['HTTP_USER_AGENT'], 'Kindle') !== false
|| strpos($_SERVER['HTTP_USER_AGENT'], 'BlackBerry') !== false
|| strpos($_SERVER['HTTP_USER_AGENT'], 'Opera Mini') !== false
|| strpos($_SERVER['HTTP_USER_AGENT'], 'Opera Mobi') !== false ) {
$is_mobile = true;
} else {
$is_mobile = false;
}
return $is_mobile;
}
代码二:
这是PHP判断手机设备函数代码,复制到PHP函数库中调用:
<?php
function is_mobile() {
$user_agent = $_SERVER['HTTP_USER_AGENT'];
$mobile_browser = Array(
"mqqbrowser", //手机QQ浏览器
"opera mobi", //手机opera
"juc","iuc",//uc浏览器
"fennec","ios","applewebKit/420","applewebkit/525","applewebkit/532","ipad","iphone","ipaq","ipod",
"iemobile", "windows ce",//windows phone
"240×320","480×640","acer","android","anywhereyougo.com","asus","audio","blackberry","blazer","coolpad" ,"dopod", "etouch", "hitachi","htc","huawei", "jbrowser", "lenovo","lg","lg-","lge-","lge", "mobi","moto","nokia","phone","samsung","sony","symbian","tablet","tianyu","wap","xda","xde","zte"
);
$is_mobile = false;
foreach ($mobile_browser as $device) {
if (stristr($user_agent, $device)) {
$is_mobile = true;
break;
}
}
return $is_mobile;
}?>
这是调用代码,可以加上if判断:
<?php if(is_mobile()):?>
设置手机端的内容
<?php endif; ?>
