PHP implements pseudo-static code based on $_SERVER['PATH_INFO'] and .htaccess.
1.根据$_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
你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。
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
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($conn);
看到上面的这个我想大家肯定懂了吧 其实这种方式用的不多的下面的给大家说第二种方法了啊
2.根据配置.htaccess来实现。
先说下.htaccess文件怎么创建吧,在网站根目录下建立个记事本然后双击打开点击另存为 文件名写成
.htaccess ,保存类型选择所有文件,编码选择utf-8的编码好的这是你就在目录看到这个.htaccess文件了
首先在apache 开启mod_rewrite.so,AllowOverride None 这里有两处 替换为 AllowOverride All
比如href 地址写成 one_new-id-1.shtml //这个意思是one_new.php?id=1
这里的.htaccess 就可以这么写了
<IfModule rewrite_module> #写你的rewrite规则 RewriteEngine On # 可以配置多个规则,匹配的顺序是从上到下 RewriteRule one_new-id-(\d+)\.shtml$ one_new.php?id=$1 //这里的$1 代表的是第一个参数啊 RewriteRule abc_id(\d+)\.html$ error.php #设置404错误 #ErrorDocument 404 /error.php </IfModule>
你在one_new.php 页面echo $_GET['id'] 肯定会输出 id的值了

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
