php错误提示
项目出错了,但运行的时候页面一片空白,不知道错在哪里.
在php.ini里error_reporting = E_ALL修改
重启后运行发现还是没有错误提示
回复讨论(解决方案)
display_errors = On
这样才能看到错误信息
仅 error_reporting = E_ALL 是没有用的
因为 error_reporting 要到程序运行期间才生效，如果错误发生在编译期间呢？
在php.ini有如下
; display_errors
; Default Value: On
; Development Value: On
; Production Value: Off
我把1,2,分号去掉.
这样的话我有个疑问,那些警告会显示出来吗?
因为之前连接mysql(说这个连接以后会被遗弃),老是有警告,后来用error_reporting设置忽略警告
重新配置环境
在php.ini有如下
; display_errors

你这些是配置文件中的说明部分，实际的配置指令如下
http://cn2.php.net/manual/zh/errorfunc.configuration.php#ini.error-reporting
如版主提供给你的
display_errors = On
还有对于线上的服务器是不应该把它打开的，错误信息中会显示你文件的路径以及资源信息(例如数据库帐号密码)，可以让它显示在apache或者nginx的errorlog中
PS: 学PHP要把手册多看看

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.

Explain late static binding in PHP (static::).
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.
