PHP权限登录,该怎么处理
PHP权限登录
用 户 名(user):_____
密 码(password):_____
选择身份(user_id):_____ <----这里是一个下拉菜单,有学生教师和管理员3个值
在按submit时,数据传送到login.php中
在login中要怎么写代码让不同身份的id登录记录在session里并跳转到不同界面。
在config.php中有连接数据库代码可以直接调用。
$db=mysql_connect('localhost','root','123456') or die(数据库连接失败!);
mysql_select_db('bishe');
?>
没有使用过SESSION,不知道该怎么写····
------解决方案--------------------
简单的很! 在代码最开头session_start(),初始化SESSION。后面就可以直接给$_SESSION超级全局变量赋值,或者读取。

------解决方案--------------------
<?php session_start(); … $_SESSION['身份_id'] = ''; if($_SESSION['身份_id']=='XXX'){ header("location:http://www.baidu.com"); } if($_SESSION['身份_id']=='XXX'){ header("location:http://www.google.com"); } …
最好是写个函数。
权限是个大问题。不是是说跳转就能解决了。
------解决方案--------------------
session_start(); if(@$_POST["login"]) { echo "<script language=\"javascript\">location.href='admin.php';</script>"; }
在if里嵌套你自己的条件跳转到你想去的页面
先做用户身份验证
根据用户身份取得权限字,保存于 session 中
所有需要身份验证的页面都要在进入时验证身份(通过权限字)
session没有限制你保存什么,但是出于编写的快捷,资源的占用等考虑,一般都使用数字来存储。
在ini里设置auto session也可以。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.

There are four main error types in PHP: 1.Notice: the slightest, will not interrupt the program, such as accessing undefined variables; 2. Warning: serious than Notice, will not terminate the program, such as containing no files; 3. FatalError: the most serious, will terminate the program, such as calling no function; 4. ParseError: syntax error, will prevent the program from being executed, such as forgetting to add the end tag.

In PHP, the difference between include, require, include_once, require_once is: 1) include generates a warning and continues to execute, 2) require generates a fatal error and stops execution, 3) include_once and require_once prevent repeated inclusions. The choice of these functions depends on the importance of the file and whether it is necessary to prevent duplicate inclusion. Rational use can improve the readability and maintainability of the code.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

HTTP request methods include GET, POST, PUT and DELETE, which are used to obtain, submit, update and delete resources respectively. 1. The GET method is used to obtain resources and is suitable for read operations. 2. The POST method is used to submit data and is often used to create new resources. 3. The PUT method is used to update resources and is suitable for complete updates. 4. The DELETE method is used to delete resources and is suitable for deletion operations.
