Today, I will talk to you about the two methods of PHP code to determine whether a device is a phone or a tablet. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something from this article.

Now the mobile Internet is more and more developed, and many websites are popular for mobile browsing. In order to better display the web page on the mobile side, we all choose to use CSS media query to make responsive templates, but this also has some disadvantages. For example, the structure of some websites is CMS type, and there is too much content to display, while using CSS media query design response style, it will only be hidden but still loaded. In order to enable the mobile side to display content more quickly, we can use this PHP to judge the mobile device code, which can easily display or not display custom content.

When doing WEB development, you often need to match the pages of mobile devices, of course, you can directly make the site responsive, but if you do not want to do so, you can use PHP to determine the device type, and then display the appropriate interface and content. Today we share a way to use PHP to determine whether a device is a phone / tablet. The method comes from WordPress (wp-includes/vars.php:125) and is suitable for most types of 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 function code for PHP to judge the mobile device, and copy it to the PHP function library to call:

This is the calling code, which can be judged by if:

Set the content of the mobile phone
