或者说
php如何获取用户连接到服务器时所使用的端口
内容 ***************************************************
在百度中查到说是用 $_SERVER['REMOTE_PORT'] 函数可以获取端口,我在本地php环境试了一下在我们登录或退出能获取我的端口，但是我东西移到我的服务器上,就获取不到,就大虾们帮忙解决下！感激不尽！！！
回复讨论(解决方案)
服务器是windows iis服务
这个是不是地址中有端口才能获取端口啊，服务器上一般都是80端口，是默认的。
你说的是客户端的端口，还是服务器端口？
是网监需要
要求网站记录用户登录和退出的ip和端口！！！
肯定不是80端口了，是用户访问服务器的端口,这个数是不停在变的
php 在低版本的 IIS 中是没有 $_SERVER['REMOTE_PORT'] 的（window 2008 + IIS7.5 中有）
你需要在微软官网下载 REMOTE_PORT 相关补丁

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?
Apr 17, 2025 am 12:06 AM
In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
How does PHP type hinting work, including scalar types, return types, union types, and nullable types?
Apr 17, 2025 am 12:25 AM
PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
