php跳转语句不同写法的安全性问题
这样写
echo "Location.href='../login.php';";
和这样写
echo "Location.href=/"../login.php/";";
在安全性问题上有什么区别么。
回复讨论(解决方案)
第二句能正常输出么？
呃，两句的引号都有问题
这样写
echo "Location.href='../login.php';";
和这样写
echo "Location.href=/"../login.php/";";
在安全性问题上有什么区别么。
抱歉 是这样的
1. echo "location.href='../login.php';";
2. echo "location.href=/"../login.php/";";
问题补充
前后有
echo "<script>"; <br /> <br /> echo "</script>";
这样写
echo "Location.href='../login.php';";
和这样写
echo "Location.href=/"../login.php/";";
在安全性问题上有什么区别么。
抱歉 是这样的
1. echo "location.href='../login.php';";
2. echo "location.href=/"../login.php/";";
这个第二句还是有问题的，是不是问的是反斜杠啊？
1、都写到页面里了，没有安全性可言
2、
href='../login.php'
是相对当前路径的上级
href="/../login.php/";
是网站的上级目录，已经越出范围了！
这样写
echo "Location.href='../login.php';";
和这样写
echo "Location.href=/"../login.php/";";
在安全性问题上有什么区别么。
抱歉 是这样的
1. echo "location.href='../login.php';";
2. echo "location.href=/"../login.php/";";

就是反斜杠，不好意思哈，没表达清楚
1. echo "location.href='../login.php';";
输出的是 location.href='../login.php';
2. echo "location.href=\"../login.php\";";
输出的是 location.href="../login.php";
你说他们有什么差别？
js 的字符串可以用单引号括起，也可以用双引号括起

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
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,
Describe the SOLID principles and how they apply to PHP development.
Apr 03, 2025 am 12:04 AM
The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Apr 03, 2025 am 12:04 AM
Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
