session url php
RewriteRule ^index.html&fun=000$ gyjw/check.php重写了url我的登陆页面
<?php session_start(); //使用session存储用户信息 if(isset($_POST["username"])) { $ss_user_id=""; //利用User累的IsValid()方法判断所输入的用户名和口令是否正确 require_once("user/UserClass.php"); $user=new User(); //如果正确,转到系统首页 if($user->IsValid($_POST["username"],$_POST["password"],$ss_user_id)) { $_SESSION["ss_user_id"]=$ss_user_id; echo "<script language='javascript'>"; echo " location='index.html';"; echo "</script>"; } //如果不正确,转到登陆页面 else { echo "<script language='javascript'>"; echo " alert('用户名或密码错误');"; echo "</script>"; } }?>主页的php
<?php include 'http://localhost/gyjw/index.html&fun=000';?>//省略html部分check.php
<?php if(! isset($_SESSION['ss_user_id'])) { echo "<script language='javascript'>"; echo "alert('您的用户无权进行此操作!');"; echo "top.location='login.html';"; echo "</script>"; exit; }?>问题是登陆成功跳转至主页的时候,先跳转至check.php,之直接就显示了'您的用户无权进行此操作!',说明$_SESSION['ss_user_id']不存在了。然后如果修改了主页的php
<?php include ("check.php");?>就存在这个$_SESSION['ss_user_id']正常显示了主页内容。
麻烦各位大侠帮助解决!

check.php 中缺少 session_start();
check.php 中缺少 session_start();
呃,不小心删掉了,但不是这个问题。
check.php 中缺少 session_start(); 通过观察生成的session文件sess_...我发现如果include里面用的是check.php,就只会生成一个sess_,如果include里面放的http://localhost/gyjw/index.html&fun=000,就会生成两个sess_,其中一个是没有数据的,这是不是说明在跳转http://localhost/gyjw/index.html&fun=000的时候系统又重新生成了一个sess_,所以$_SESSION['ss_user_id']才没有值,要怎么解决呢?

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.

Dependency injection provides object dependencies through external injection in PHP, improving the maintainability and flexibility of the code. Its implementation methods include: 1. Constructor injection, 2. Set value injection, 3. Interface injection. Using dependency injection can decouple, improve testability and flexibility, but attention should be paid to the possibility of increasing complexity and performance overhead.

Implementing dependency injection (DI) in PHP can be done by manual injection or using DI containers. 1) Manual injection passes dependencies through constructors, such as the UserService class injecting Logger. 2) Use DI containers to automatically manage dependencies, such as the Container class to manage Logger and UserService. Implementing DI can improve code flexibility and testability, but you need to pay attention to traps such as overinjection and service locator anti-mode.
