关于php中isset的问题
if ( isset($_POST['pass']) & isset($_POST['name']) & @MD5($_POST['pass'])==" admin" & @$_POST['name']==" admin" )
这一句中为什么我在前端输入用户名admin跟密码admin时始终进不去呢？
if ( isset($_POST['pass']) & isset($_POST['name']) & @MD5($_POST['pass'])==" admin" & @$_POST['name']==" admin" )
{
?>
}else{
?>
}
?>
回复讨论(解决方案)
MD5($_POST['pass'])=="admin"
这是永远都不会成立的
md5 对任何值（包括空串）都返回一个长度为 32 字节的串
一个&是位运算
两个&&才是并且关系
还有任何md5的值都是32位的字符串
应该怎样修改呢
if ( isset($_POST['pass']) && isset($_POST['name']) && $_POST['pass']=="admin" && $_POST['name']=="admin" )

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.
