$current_uri = $_SERVER['REQUEST_URI'];
$current_uri = detect_uri();This code will call the `detect_uri` function which will return the current request URI and store it in the `$current_uri` variable. However, this code will only work if the `detect_uri` function is part of a package or library that is included in the project. To determine the package library that includes the `detect_uri` function, you could try searching for this function in popular PHP packages or libraries like Symfony, Laravel, or CodeIgniter. Alternatively, you could search for the function name in online PHP resources like PHP.net or Stack Overflow.
