Answer 1

You can use getcwd() function to get the current working directory. Manual: getcwd()

<?php
//Your project location like an example in Unix 
// /var/www/Test/Test2/Test3/wonderful.pdf
// then you $subfolder var will get this: Test2/Test3
$filename = 'wonderful.pdf';
$subfolder = 'Test3';
$delete_file =  getcwd() . DIRECTORY_SEPARATOR . $subfolder . DIRECTORY_SEPARATOR . $filename;

unlink($delete_file);

?>

Hope it helps.
