PHP实现网址伪静态的方法:1、使用函数【$_SERVER['PATH_INFO']】操作实现;2、配置【.htaccess】来,网站建设时使用【mod_rewrite】模块来实现伪静态。
PHP实现网址伪静态的方法:
1.根据$_SERVER['PATH_INFO']
来操作实现。
举个列子比如你的网站的地址是 http://127.0.0.1/show_new.php/look-id-1.shtml
echo $_SERVER['PATH_INFO']
出来的结果就会是
/look-id-1.shtml
看到这个我想大家可能已经明白了。完整的demo

index.php
代码如下:
index.php $conn=mysql_connect("localhost","root","root")or dir("连接失败"); mysql_select_db("tb_demo",$conn); $sql="select * from news"; $res=mysql_query($sql); header("content-type:text/html;charset=utf-8"); echo "<h1 id="新闻列表">新闻列表</h1>"; echo "<a href='add_news.html'>添加新闻</a><hr/>"; echo "<table>"; echo "<tr><td>id</td><td>标题</td><td>查看详情</td><td>修改新闻</td></tr>"; while($row=mysql_fetch_assoc($res)){ echo "<tr><td>{$row['id']}</td><td>{$row['title']}</td><td><a href='show_new.php/look-id-{$row['id']}.shtml'>查看详情</a></td><td><a href='#'>修改页面</a></td></tr>"; } //上面的红色的地址本来该是show_news.php?act=look&id={$row['id']} echo "</table>"; //关闭资源 mysql_free_result($res); mysql_close($conn);
show_new.php
页面
代码如下:
show_new.php header("Content-type:text/html;charset=utf-8"); $conn=mysql_connect("localhost","root","root"); mysql_select_db("tb_demo",$conn); mysql_query("set names utf8"); $pa = $_SERVER['PATH_INFO']; //$pa 打印出来的值是 /look-id-1.html //通过正则表达式匹配获取的url地址 if(preg_match('/^\/(look)-(id)-([\d])\.shtml$/',$pa,$arr)){ $act = $arr[1]; //这个是请求的look方法 $id = $arr[3]; //这个是获取的id 值 $sql="select * from news where id= $id"; $res=mysql_query($sql); $res = mysql_fetch_assoc($res); echo $res['title']."<hr>".$res['content']; }else{ echo "url地址不合法"; } mysql_close($conn);
看到上面的这个我想大家肯定懂了吧 其实这种方式用的不多的下面的给大家说第二种方法了啊
2.根据配置.htaccess
来实现。
Apache的mod_rewrite是比较强大的,在进行网站建设时,可以通过这个模块来实现伪静态。
主要步骤如下:
1.检测Apache是否开启mod_rewrite
功能
可以通过php提供的phpinfo()函数查看环境配置,找到“Loaded Modules”,其中列出了所有apache2handler已经开启的模块,如果里面包括“mod_rewrite”,则已经支持,不再需要继续设置。如果没有开启“mod_rewrite”,则打开目录 apache目录下的“/apache/conf/” ,找到 httpd.conf 文件,再找到“LoadModule rewrite_module”,将前面的”#”号删除即表示取用该功能。 如果没有查找到“LoadModule” 区域,可以在最后一行加入
“LoadModule rewrite_module ,modules/mod_rewrite.so”
(独占一行),之后重启apache服务器。再通过phpinfo()函数查看环境配置就有“mod_rewrite”为项了.。
2.让apache服务器支持.htaccess
如何让自己的本地APACHE服务器支持:“htaccess”呢? 只需修改apache的httpd.conf设置就可以让 APACHE支持“.htaccess”了。打开 APACHE目录的CONF目录下的httpd.conf文件,找到: Options FollowSymLinks AllowOverride None 改为 Options FollowSymLinks AllowOverride All 就行了。
3.建立.htaccess
文件
建立.htaccess文件时要注意,不能直接建,方法是通过记事本中的另存为菜单,在文件名窗口输入:“.htaccess”,然后点击保存。
4.rewrite规则学习
在新建.htaccess文件之后,就在里面写入以下内容: RewriteEngine on #rewriteengine为重写引擎开关on为开启off为关闭 RewriteRule ([0-9]{1,})$index.php?id=$1 在这里,RewriteRule是重写规则,是用正则表达式的句子,([0-9]{1,})表示由数字组成的,$表示结束标志,表示以数字结束!如果要实现伪静态页面,
规则如下:
RewriteEngine on RewriteRule ([a-zA-Z]{1,})-([0-9]{1,}).html$index.php?action=$1&id=$2
在为个正则表达式中,([a-zA-Z]{1,})-([0-9]{1,}).html$是规则,index.php?action=$1&id=$2是要替换的格式,$1代表第1括号匹配的值,$2代表第二个括号的值,如此类推! 测试PHP脚本如下: index.php文件中的代码如下:
echo ‘你的Action值为:’ . $_GET['action']; echo ‘ ’; echo ‘ID值为:’ . $_GET['id']; ?>
在浏览器地址栏输入:
localhost/page-18.html
输出的是:
你的Action值为:page ID值为:18
