This article provides a step-by-step guide on how to create, retrieve, update, and delete cookies using controllers in the Yii framework. It includes practical code examples to help developers effectively manage cookies in web applications. Ideal for beginner and intermediate PHP developers.

How to use the session_set_cookie_params function in PHP to correctly configure session cookies for better security and compatibility with modern browsers. This function allows you to set various cookie parameters like lifetime, path, domain, and security features.

When PHP uses cURL to perform multiple HTTP requests, sometimes we want to share certain data between multiple requests, such as cookies, DNS caches, or SSL sessions. At this time, you can use curl_share_init() and related functions to implement sharing. However, many developers encounter a common problem when trying to use the feature: This article will analyze the causes and solutions of this problem in detail.

cURL resource sharing allows multiple cURL sessions to share certain resources, reducing repeated initialization. In real-world applications, multiple cURL requests often need to perform similar operations, such as DNS resolution or handling cookies. By sharing these resources, developers can improve request efficiency and avoid redundant network requests and computations.

When using PHP for network requests, we often encounter situations where we need to simulate browser behavior, especially the verification problem of verification codes. Verification codes are techniques used to prevent automated programs from submitting forms. They usually require users to enter a displayed character or click on a specific picture to verify human identity. In this case, using the cURL library to simulate browser behavior is an effective solution.

cURL is a very important tool when writing PHP scripts for HTTP requests, especially when we need to simulate multiple requests from the browser, how to keep logged in or share sessions becomes especially important. cURL provides a very useful function curl_share_init(), which can help us share cookies in multiple cURL sessions, avoiding login again every time a request is sent, thus greatly improving the reuse efficiency of login state.
