Browser Detector Script in PHP Free Source code and Tutorial
Introduction
Table of Contents
This tutorial will teach you how to detect your browser using PHP. This can be useful for customizing your web page to display different content depending on which browser is being used. You will need to have a basic understanding of PHP syntax to follow this tutorial.
In order to detect your browser using PHP, we need to first understand the various functions that are available. In PHP, there is a global variable known as $_SERVER. This variable is mostly used for printing the server and the environment information.
This article will guide you through the development of detecting the browser in PHP. Let’s get started with the development.
Objectives
By the end of this tutorial, you will be able to:
- Create a PHP script that detects and display the browser used by user.
- Use the necessary function to retrieve the server or browser information.
- To integrate and apply the source code in your projects.
Relevant Source code
Requirements
- XAMPP
- Text editor (VS Code, Sublime, Brackets), download and install a text editor of your choice
Line 19-33 – this is the PHP script that will detect and display the browser used.
Line 20-31 – we have created a function and the name is detect.
Line 21 – we have declared a variable $info that will hold the value of $_SERVER.
$_SERVER is a PHP variable that holds all information about the web server. It’s referred to as a superglobal.
The user agent string is a text that browsers transmit to the webserver to identify themselves, allowing websites to provide alternative content depending on the browser or browser compatibility.
The strpos() function finds the position of the first occurrence of a string inside another string.
Line 32 – we are ready to call the function. Take note that a function or a method will not run automatically until it is being called.
<?php
function detect(){
$info = $_SERVER['HTTP_USER_AGENT'];
if(strpos($info,"Chrome") == true)
echo "<h4>You are using Google Chrome</h4>";
if(strpos($info,"Firefox") == true)
echo "<h4>You are using Firefox</h4>";
elseif(strpos($info,"Trident/7") == true)
echo "<h4>You are using Internet Explorer</h4>";
else{
echo "<h4>Other Browser</h4>";
}
}
detect();
?>
