php - Have user query www.example.com/parameter and use that parameter without changing URL in url bar

Solution:

Usually who needs this kind of feature uses Routers.

Routing is the process of taking a URI endpoint (that part of the URI which comes after the base URL) and decomposing it into parameters to determine which module, controller, and action of that controller should receive the request.

Basically you can take your url and divide it in parameters. The response it's related to the input url. There are some good libraries in php which allows you to handle routers, for example:

• Dispatch: https://github.com/noodlehaus/dispatch
• Phroute: https://github.com/mrjgreen/phroute

In phroute you can solve your problem just with:

$router->get(['/user/{name}', 'username'], function($name){
    //retrieve $name information
    return 'Hello ' . $name;
})
Copy code

Just for information, every MVC framework uses router as standard.

Solution:

Using .htaccess File

RewriteEngine on
RewriteRule ^/([a-zA-Z0-9])$ /users.php?name=$1
Copy code

I hope this will solve your issue, now what it will do, on the front or to the public url is likehttp://www.example.com/john butusers.php script on your server will receive a GET parameter name which will have the value john.

Just make sure apache mod_rewrite is turned on.

Solution:

With Apache's rewrite module, you can do a rewrite or a redirect.

Redirect means, send a response (status code 301, 302) to the client and ask to fetch another URL. This causes the browser's URL bar to change to the new URL. This happens, when you add the flag to a rule, e.g.

RewriteRule ^foo$ /bar.html [R,L]
Copy code

RewriteRule ^foo$ http://www.example.com/bar.html [L]
Copy code

RewriteRule ^foo$ /bar.html [L]
Copy code

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^john$ /users.php?name=john [L]
Copy code

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ /users.php?name=$1 [L]
Copy code
