Use This Code; Working Perfectly:

                $CV = trim($_POST["CV"]);    
                $FnameArr = explode('.',$CV);
                $ext = end($FnameArr);
                if(strtolower($ext)!='pdf'){
                    // YOUR CODE GOES HERE.
                }
                else{
                    echo "you didnt upload a pdf file";
                    die();  
                }
