Now the mobile Internet is becoming more and more developed, and many websites have popularized mobile browsing , in order to better display the web page on the mobile phone, we all chose to use CSS media queries to create responsive templates, but this also has disadvantages. For example, the structure of some websites is CMS type, and there is too much content to be displayed, and using The CSS media query design is responsive and will only be hidden but still loaded. In order to display the content more quickly on the mobile phone, we can use this PHP to determine the mobile device code. Using this code can easily display or not display customized content. content.
When doing WEB development, you often need to use page matching for mobile devices. Of course, you can directly make the website responsive, but if you don’t want to do this, you can use PHP to determine the device type and then display it. Corresponding interface and content. Today I will share a method of using PHP to determine whether the device is a mobile phone/tablet. The method comes from WordPress (wp-includes/vars.php:125) and is suitable for most types of mobile phones/tablets:
Method 1:
/** * 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; }
Code 2:
This is the PHP function code to determine the mobile phone device. Copy it to the PHP function library and call it:
<?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; }?>
This is the calling code, you can add if judgment:
<?php if(is_mobile()):?>
Set content on mobile phone
<?php endif; ?>
