Hi, I have this PHP code:

<?php
          if (isset($_POST['page'])) {
              $file = fopen(ROOT . 'pages/' . $_POST['page'], "wb");
              if(!$file === false) {
                  echo fwrite($file,  stripslashes($_POST['content']));
                  fclose($file);
                  $title = strtolower(str_replace(" ", "_", $_POST['title']));
                  rename(ROOT . 'pages/' .  $_POST['page'], ROOT . 'pages/' . $title . '.php');
              }
         }
      ?>

And it keep adding newlines and spaces where i don't what them. Please can you help me!
