How directly input and get parameter from url? [duplicate]

Question

Let say my code file is code.php and I can access it by :

localhost/test/code.php

Now I want if I enter address bar:

localhost/test/code.php?someparameter

it will automatically

overwrite "someparameter" string to a dummyfile.txt.

Is it possible to do it that way ?

I know we can use :

 $_SERVER['REQUEST_URI'];

to get URI but how could we add the param directly to the url and it still go to the same code file and process ??? I dont want to use java script here coz my server only support php.

thanks, but its not really duplicate. How to process the thing just by entering on url, not action on webpage. I think "@Request.QueryString" might have something to do here. — user1314404

You will need to look further in writing your parameter, but it is possible to catch whether your "parameter" is set,

if (isset($_GET['parameter'])) {
  // do your thing
}

how could we just type on url, press enter, then in the code it could know variable is set and assign param value to that variable ?

Ok, I got the answer for my question. Well it quite simple when u know it : if (isset($_GET['param'])) { // do your thing file_put_contents('dummyfile.txt',$_GET['param']); } //and at the link, just type: localhost/test/code.php?param=value

You got it! Cheers. It was unclear whether you would add a value to the url parameter.

You can use $_GET["parater_name"] to get the parameter from url. And you can use $_POST for parameters in post request. $_REQUEST for get,post and session parameters.

Its quite hard for me to imagine the solution. Do I need to declare a variable in the code, then use get to get the value then post again the value ? What I mean here is ust enter the url and it will appear the param in the text file, no need andy action on the webpage.
