Basic Routes in Web Development

When it comes to web development, routes are a very important concept to understand. Routes are essentially the URLs that users can use to access different pages or resources on your website. In this post, we will be discussing the basics of routes and how they work in web development.

What are Routes?

Routes are a way to map URLs to specific actions or resources on your website. For example, if a user visits the URL, you would want to show them the "About" page on your website.

Routes can be defined in various ways depending on the web framework or technology being used. In general, routes consist of a URL pattern and a corresponding action or resource that should be returned when that URL is visited.

How are Routes Defined?

Routes are typically defined in a configuration file or in code using a web framework or routing library. In PHP, for example, routes can be defined using the $_SERVER['REQUEST_URI'] variable in conjunction with an if/else statement. Here's an example:

    if ($_SERVER['REQUEST_URI'] == '/about') {
        include 'about.php';
    } elseif ($_SERVER['REQUEST_URI'] == '/contact') {
        include 'contact.php';
    } else {
        include 'home.php';

In this example, we're checking the $_SERVER['REQUEST_URI'] variable to see what URL the user is trying to access. Depending on the URL, we include the appropriate PHP file to display the corresponding content on our website.

Other web frameworks and libraries have their own ways of defining routes. In Laravel, for example, routes are defined in a routes/web.php file using a more expressive and readable syntax.

Route Parameters

Sometimes, you may want to pass dynamic parameters in your routes. For example, if you have a blog website, you might want to create a route that allows users to view a specific blog post based on its ID number.

Route parameters can be defined using placeholders in the URL pattern. Here's an example:

    // Route with a parameter
    Route::get('/blog/{id}', function ($id) {
        return view('blog', ['id' => $id]);

In this example, we're defining a route that expects a parameter called "id" in the URL. When a user visits a URL like /blog/123, the value "123" will be passed as the parameter to our route function. We can then use this parameter to query our database or perform other actions on our website.


Routes are a fundamental concept in web development that allow you to map URLs to specific actions or resources on your website. By understanding how routes work and how to define them, you can create more complex and dynamic web applications that provide a better user experience for your visitors.
