Description
Priority
Interface function
Flexible and cannot be reused
Every page using the editor needs to be written once
Highest
Override parameters in custom and system configuration files
Custom configuration file
Flexible and reusable
Multiple custom configuration files can be defined according to usage scenarios, and different configuration files can be referenced in different pages
Medium
Override parameters in system configuration file
System configuration file
Inflexible
Global nature, affecting all programs
Minimum
The above has implemented the function of online text editing, but has not implemented the function of file management.
Reason: ck separates online editing and file management. If you want to implement file management, you must use ckfinder
Ckfinder installation
Exactly the same steps as Ckeditor
Ckfinder file directory
Use Ckfinder
To load the use of ckfinder in Ckeditor's configuration items, load several static pages, and manage user files
Load in customized configuration file
Effect
However, because Ckfinder does not allow users to upload files by default, they do not have permission to upload files
Modify configuration file
Permissions open
Find the config.php file to open permissions
Modify permissions and open all permissions
Effect
There is a problem with the above path
Modify file upload path
Find the path in config.php and modify it
Modify path
Effect
Modify the file upload directory structure
The directory structure cannot be a single folder under a certain file type. The folder structure should be determined appropriately based on the amount of file uploads. Year/month/day
Modify the file shelf structure in config.php
Modify structure
Effect
During the file upload process, if the file name is in Chinese or special characters, the system cannot process it. After uploading, garbled characters will appear. The file needs to be renamed after it is uploaded.
Ckfinder does not provide a mechanism for duplicate names.
How to achieve it? Modify the source code.
Implement file renaming
Source code file path
Add a new function to get random names
Where to call this function? How to use?
Effect
The current file manager can add, delete, modify and check files on the server on the browser side. This is quite dangerous and is absolutely not allowed.
Control user permissions
Control user operations on server-side files
File permissions can be controlled in config.php.
Modify
Effect
Permissions that must be opened for file upload
Ckeditor edit content submission
2 Submit data after editing
3 PHP receives data and needs to escape the data, addslashes
4 Output data, needs to be reversed, stripslashes

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.
