php - Drupal 6 プログラムで \r\n 表示を追加

Question

drupal Web サイトにストーリー ノードを追加する PHP スクリプトがあります。

function post_to_webpage($title, $body, $teaser, $promote) {
//set the working directory to your Drupal root
chdir($_SERVER["DOCUMENT_ROOT"].'/webpage/');

//require the bootstrap include
require_once './includes/bootstrap.inc';

drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL); 
//(loads everything, but doesn't render anything)
$node = new stdClass();
$node->type = 'story';
$node->title = $title;
$node->body = $body;
$node->teaser = $teaser;
$node->uid = 1;
$node->status = 1;
$node->promote = $promote;
$node->format = 2;
$node->sticky = 1;

node_save($node);

return $node->nid; }

ただし、これらのノードのコンテンツに r\n\ が頻繁に表示されます。何が原因でしょうか?
