   $thisdir = "/associate/";
   $folderPath = $rootfolder.$thisdir.$name."/"; // desired directory

if(!is_dir($folderPath)){
        mkdir($folderPath, 0777, true);

Copy function in php accept two names and not only directory.

So instead

copy("file1.txt", $folderPath)

copy("file1.txt", $folderPath . "/file1.txt")

and use error feedback to understanding better

if (copy("file1.txt", "folder1/file1.txt")) {
    echo "File Copied";
} else {
    $errors= error_get_last();
    echo "File not copied, " . $errors["messages"];
}
