PHP 判断手机设备的代码
现在移动互联网越来越发到,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。
<meta charset="utf-8"> 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; ?>
效果图:
