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; ?>
