Can you add a variable to a file path?

Question

I was wondering if you can add a variable to a file-path.

Example:

path: C:\\users\\john\\school\\hardware.properties";

I want to make a variable of the word preceding the . (dot) - in this case, "hardware" - so the user can write a name in a form and search/get another property.

Be aware that inviting user-supplied data into a path may be a vulnerability because they can add relative path changes (like `../`) and go where you don't want them to. You must sanitize user input. — mickmackusa, Mar 10 '20 at 19:55

You can just make it a string and add the var into it

$name = $_POST['name']

$path = "C:/.../".$name.".properties"

I just make more sure what Jasper B want to write:

In your form you have some submit input and text input.

You will get datas from inputs so you will just access them like:

$name = $_POST["name"];

After you just put $name variable to path like:

$path = "C:\users\john\school\".$name.".properties";
