#实现一个简单的搜索框，然后通过127.0.0.1连接本地的apache服务，window平台，root_doc,是E:/CodeEdit/php，下面是php解析脚本：

<html><body><head><title>search result</title></head><script language = "php">$item = trim($_POST['searchItem']) ;if (!isset($item)){	echo "<p>what you want to search..</p>";	//$item = "javascript";}if (!get_magic_quotes_gpc()){	$item = addslashes($item);}$db = new mysqli("localhost", "root", "cai123",'phpdb');if (mysqli_connect_errno()){	echo "<p>can not to connect to database</p>";}$query = "SELECT * FROM books WHERE bookname LIKE"."'%".$item."%'";$result = $db->query($query);if (!$result){	echo "<p>no record was found...</p>";}$items = $result->fetch_object();echo "<ul><li>ISBN: ".stripslashes($items->isbn)."</li>";echo "<li>bookname: ".stripslashes($items->bookname)."</li>";echo "<li>authors: ".stripslashes($items->authors)."</li>";echo "<li>prices: ".doubleval($items->prices)."</li></ul>";//$item->free();$db->close();</script></body></html>

### 输入关键字搜索时，地址栏显示file:///E:/CodeEdit/php/127.0.0.1/formSearch.php，找不到网页。
##但是我修改一下：$item = "javascript" ，直接在浏览器输入：127.0.0.1/formSearch.php 可以收到正确回复，在命令行输入:php formSearch.php 也可以收到正确回复。

？？不知道是怎么回事？？本人新手啊，刚学php才一周不到。

路径跳转有问题

浏览器输入：127.0.0.1/formSearch.php
使用的是 http 协议，http://127.0.0.1/formSearch.php
只不过浏览器友好的免去了你输入 http:// 的麻烦

而 file:///E:/CodeEdit/php/127.0.0.1/formSearch.php
是文件系统协议

显然你的 html 代码不是通过 web 服务器访问的
所以应这样写
