passing variable in URL for ajax jquery

Question

I am trying to understand a $.ajax call:

var url = "/api/followuser.php/"  + userID ;

$.ajax(url, { 'success': function(data) {
                    /do something
                     }
});

Thia ajax call is required to pass the variable 'userID' to the file '/api/followuser.php' to make a database query(php/Mysql).

I don't have access to '/api/followuser.php' .

Can anyone help me figure out how to get the variable 'userID' from the URL in a php file to be used in a database query.( I know how to pass variable as 'data: userID,' in $.ajax and use it in a php file but i want to understand this particular example)

There is likely a mod_rewrite action on the server in question, which is an interpretation of a standard url, like the other answer from @tadman suggests. check for .htaccess files if you're on apache, or other configuration files at the server level. — BReal14

Maybe you mean followuser.php?user_id= instead? The slash is probably causing issues since that's interpreted as a directory by the server:

var url = "/api/followuser.php?user_id=" + userID;

Is this the only option because actually its written like url = base.api + "/" + userID ; and base.api = "/api/followuser.php";

That's highly irregular. Are you sure?

Yes. I don't know what you mean by 'highly irregular' but the "/" is definitely there instead of ?.

you need to use GET method with ajax, to do this you can use next example

$.ajax({
     url: "/api/followuser.php",
     type: "GET",
     data: {variable: "valueofvariable"},
     success:  function(data) {
        console.log(data);
     }
});

so in your php file you can read the variable like this

<?php

    if(isset($_GET["variable"])){
     echo $_GET["variable"];
     // if this works you should see in console 'valueofvariable'
    }

?>
