php引入文件之策略,有难度,请给个规范
c://www/head.php
c://www/db.class.php
c://www/query/wc.php
在head.php中有文件db.class.php
即在head.php中有require_once "db.class.php";
在head.php中有<script><br /> 当所有其他文件来包含head.php会出错(在query文件下)<br /> <br /> 当wc.php这样引用时会报错,就是找不到db.class.php<br /> include ("../head.php");<br /> 我在右键查看源代码:发现给解析成了:<br /> c://www/query/image/js.js<br /> 你知道,实际上的在<br /> c://www/image/js.js<br /> 只是用了inclue了给加载错了<br /> 这个应该怎么写??? <div class="tag "> </script>


------解决方案--------------------
1、
head.php 中 require_once "db.class.php";
wc.php 中 include ("../head.php"); 
不会出现找不到 db.class.php 的问题

2、head.php 中 <script> 使用了相对路径<br /> 对于 query/wc.php 会出现文件找不到的问题<br /> 应使用绝对路径<br /> <script src="<span style="color: #FF0000;">/image/js.js"><br><font color='#FF8000'>------解决方案--------------------<br>用一个变量来做项目名啦 <br><font color='#FF8000'>------解决方案--------------------<br><script src="wms4/image/js.js">---这是绝对引用<br /> <script src="/wms4/image/js.js">--这是相对<br /> ?????<br /> 正好反了 <div class="clear"> </script>
