我可以看到xml文件，当我运行PHP脚本在终端使用phpfilename.php但不能看到它，当我尝试从apachelocalhost在我的浏览器。那我该怎么办？

编辑：

当我打开apache2的错误日志时，我看到了这个。

我认为你的xml结构不正确：

应该是这样的：

<?xml version="1.0" encoding="utf-8"?>
<books>
 <book>
    <bookcode>COMPUTER</bookcode>
    <bookname>LEARN PHP</bookname>
    <bookauthor>Balguruswamy</bookauthor>
    <publisher>Arihant</publisher>
    <price>645.50</price>
</book>
<book>
    <bookcode>Maths</bookcode>
    <bookname>Solve Trig</bookname>
    <bookauthor>A.B.C</bookauthor>
    <publisher>TM</publisher>
    <price>150.42</price>
</book>
<book>
    <bookcode>English</bookcode>
    <bookname>Prose</bookname>
    <bookauthor>D .E.EF</bookauthor>

</books>

获取xml元素的PHP代码：

<?php
     $bookxml =simplexml_load_file("book.xml");
     echo '<pre>';
     print_r($bookxml);
?>
