一些php包和phpinfo的有关问题
一些php包和phpinfo的问题
1.Liunx下的PHP包有bin、etc、include、lib、man,和win下的dev、ext、extras、pear,都分别有什么用？为什么有这样的区别？
2.我了解的是win下的ext装的是PHP扩展，php内置函数都是这里的吗？那Liunx下的扩展文件都在哪？WIN下的php.ini为什么要放在C:\windows下？
3.phpinfo的详细解释，有讲解文章吗？度娘半天没找到，里面有些扩展都不知道干嘛的，例如SPL。在ext的目录下也没找到php_spl.dll相关的dll扩展，它哪来的？
求高手指教，谢谢！

約定俗成的目錄結構...比如system32 你就能想到是win的系統目錄裏面有一堆的dll。
兩個系統是完全不同的東西只是在實現相同的效果，所以如果互相比較的話你會更迷惘的。
至於linux下的擴展在哪，如果你實在不知道 那麼 locate xxxx.so 吧... 大多數時候這些so 都會在 /usr/local/lib/ 下。
php.ini爲什麼要在windows下?其實沒有這麼規定，你可以放置在任何你能放的地方，只需要修改好路徑讓系統知道在哪。默認應該是在php的根目錄下,放在win下是因爲系統查找路徑的問題。
phpinfo具體有些啥，我也不清楚，我只關心我要用的...其他的呵呵 它在就在吧。我想要弄明白每個組建都是做什麼的，可以到php管網去找資料可能更豐富。
ext 下沒有一些dll 很正常,其實有蠻多都不是默認就有的,它哪來的？嗯...

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

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.

Explain the match expression (PHP 8 ) and how it differs from switch.
Apr 06, 2025 am 12:03 AM
In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.
