PHP生成excel时单元格内换行问题的解决方法_php技巧
翻出来源码开了下,字符串中使用换行的方法为"Name:{$name}\nAddress:{$adress}\nCity:{$city}\nCountry:{$country}\n ......"
既然"\n"起不到换行的目的,修改成"\r\n"看看.
修改 =》 提交 =》测试
得出的结果还是 没有换行!!!!
难道是操作系统兼容问题??
直接使用php runtime 常量 PHP_EOL 替代 "\r\n"
修改 =》 提交 =》测试
得出的结果还是 没有换行!!!!
什么情况? 不可能这个也解决不了 操作系统兼容性问题的换行符号。
看看到底这个xls文件是怎么用php生成的。
看了下 生成excel的代码,Oh My Lady gaga,原来是用html的格式,只是文件后缀写成xls,既然html的格式,那么应该
可以起到换行的效果吧。
继续
修改 =》 提交 =》测试
结果是 可以换行了。 可喜可贺啊。问题终于解决了。
告诉老大问题解决,此时心中甚是喜悦啊。
过了一刻钟的样子,老大跑过来说:“换行效果的问题是解决了,但是你看下,数据不好复制了。”
。。。。
省略沟通N句。
把一个单元格的数据复制下,然后 粘贴到 word中。Oh My Lady gaga, 为啥会有border????
到底什么问题?? 使用\n、
\n 把不能起到换行的相关,使用
把效果是有了,但是又出现了新问题。。。 到底如何是好?
没辙了,使用BAIDU google吧。
终于 黄天不负有心人,找到了问题的答案。

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.

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

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.

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.
