写入并保持后，怎么换行？

Question

if(fwrite($fp, $guestbook->saveXML()))
{
echo "成功";
写入后并保存后，怎么实现换行，使得下次写入在不同的行

Answer 1

我的意思是把post过来的内容，写入并保存在xml后，换行，后面写入和保存的内容就可以跟前面的不在同一行了

Answer 2

在哪输入echo " <br>";？

Answer 3

if(fwrite($fp, $guestbook->saveXML())) 
{ 
fwrite($fp,"\n");
echo "成功"; 

Answer 4

试过了4楼的，没效果，跟没加fwrite($fp,"\n");这个效果是一样的

Answer 5

if(fwrite($fp, $guestbook->saveXML())) 
{ 
fwrite($fp,"\r\n");
echo "成功"; 如果再不行 ，楼主贴上完整代码让大家看看

Answer 6

<?php
$guestbook = new DomDocument(); //创建一个新的 DOM对象
$guestbook->load('guestbook.xml'); //读取 XML数据
$threads = $guestbook->documentElement; //获得 XML结构的根
//创建一个新 thread节点
$thread = $guestbook->createElement('thread'); 
$threads->appendChild($thread);
//在新的 thread节点上创建 title标签
$title = $guestbook->createElement('title');
$title->appendChild($guestbook->createTextNode($_POST['title']));
$thread->appendChild($title);
//在新的 thread节点上创建 author标签
$author = $guestbook->createElement('author');
$author->appendChild($guestbook->createTextNode($_POST['author']));
$thread->appendChild($author);
//在新的 thread节点上创建 content标签
$content = $guestbook->createElement('content');
$content->appendChild($guestbook->createTextNode($_POST['content']));
$thread->appendChild($content);
//将 XML数据写入文件
$fp = fopen("guestbook.xml", "w"); 
if(fwrite($fp, $guestbook->saveXML()))
{
fwrite($fp,"\r\n"); 
echo "成功";
echo "<script language='Javascript'> 
       parent.location.reload(); 
        </script>";
}
else
echo "留言提交失败";
fclose($fp);
?>
我就是想把每次读进来的数据重新放在另外一行

Answer 7

fopen("guestbook.xml", "a+"); 
看看

Answer 8

$guestbook = new DomDocument(); //创建一个新的 DOM对象
$guestbook->load('guestbook.xml'); //读取 XML数据
$threads = $guestbook->documentElement; //获得 XML结构的根
//创建一个新 thread节点
$thread = $guestbook->createElement('thread');
$threads->appendChild($thread);
//在新的 thread节点上创建 title标签
$title = $guestbook->createElement('title');
$title->appendChild($guestbook->createTextNode($_POST['title']));
$thread->appendChild($title);
//在新的 thread节点上创建 author标签
$author = $guestbook->createElement('author');
$author->appendChild($guestbook->createTextNode($_POST['author']));
$thread->appendChild($author);
//在新的 thread节点上创建 content标签
$content = $guestbook->createElement('content');
$content->appendChild($guestbook->createTextNode($_POST['content']));
$thread->appendChild($content);
//=========================================================
$threads->appendChild($guestbook->createTextNode("\n"));//这样来添加换行
//=========================================================
//将 XML数据写入文件
$fp = fopen("guestbook.xml", "w");
if(fwrite($fp, $guestbook->saveXML()))
{
//fwrite($fp,"\r\n");
echo "成功";
echo " <script language='Javascript'>
      parent.location.reload();
        </script>";
}
else
echo "留言提交失败";
fclose($fp);
