国家气象局免费天气预报接口（沈阳）：http://www.weather.com.cn/data/cityinfo/101010100.html
这个接口提供了一个json格式的天气预报数据。
不知道用php怎么得到这个json，在网上找到了以下代码
但其中的httpGetRequest函数是个自定义函数，而且网上并没有放出这个函数的原型！请高手指点！
回复讨论(解决方案)
$url = 'http://www.weather.com.cn/data/cityinfo/101070101.html';$s = file_get_contents($url);print_r(json_decode($s, true));Array
(
[weatherinfo] => Array
(
[city] => 沈阳
[cityid] => 101070101
[temp1] => 10℃
[temp2] => -2℃
[weather] => 多云
[img1] => d1.gif
[img2] => n1.gif
[ptime] => 08:00
)
)
httpGetRequest无需理会，反正目的就是把文本抓下来，只是用了什么手段而已，你完全可以自写
直接获取就按版主给的file_get_contents，想省点流量就用curl或者socket发送压缩请求
先用 file_get_contents 把工作完成了，等有时间学习了curl, socket...再回头优化吧
你贴的代码中 $info 就是你得到的数据
版主就是版主，十分感谢！还有感谢snmr_com的优化建议！
版主的是正确的...
这个接口已经不更新了，获取的数据不对

What are some common problems that can cause PHP sessions to fail?Apr 25, 2025 am 12:16 AMReasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.
How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AMMethods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.
What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AMMultiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.
How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AMConfiguring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.
What are the advantages of using a database to store sessions?Apr 24, 2025 am 12:16 AMThe main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.
How do you implement custom session handling in PHP?Apr 24, 2025 am 12:16 AMImplementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.
What is a session ID?Apr 24, 2025 am 12:13 AMSessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.
How do you handle sessions in a stateless environment (e.g., API)?Apr 24, 2025 am 12:12 AMManaging sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.
