How to get current browser information in PHP

PHP obtains the current browser information. We can directly use the super global variable $_SERVER in PHP to obtain the specified browser information.

$_SERVER is an array containing information such as header, path, and script locations. The items in this array are created by the web server. There is no guarantee that every server will offer all items; servers may ignore some, or serve items not listed here.

Below we use a simple code example to obtain the current browser information.

The code example is as follows:

<?php

//获取当前浏览器的信息
echo "你的浏览器是:".$_SERVER[&#39;HTTP_USER_AGENT&#39;];

var_dump($_SERVER);

Here we get the current browser information and print it as follows:

Note: ## Prior to #PHP 5.4.0, $HTTP_SERVER_VARS contained the same information, but it was not a superglobal variable. (Note that $HTTP_SERVER_VARS and $_SERVER are different variables, and PHP handles them differently)

HTTP_USER_AGENT
