Learn how the PHP curl_multi_init() function initializes multiple cURL sessions to handle multiple URL requests simultaneously. This article provides a simple example to help you master how to use cURL for better program efficiency.

Learn about PHP's curl_getinfo() function and how to retrieve cURL request information, including the request URL, HTTP status code, request time, and more to enhance your PHP coding skills.

This article provides a detailed explanation of the PHP curl_multi_add_handle() function, demonstrating how to add multiple cURL handles to a session for efficient management. By using this function, you can send multiple HTTP requests concurrently, improving code maintainability and execution efficiency.

This article provides a detailed guide on using the curl_setopt_array() function in PHP to batch set cURL options. By using this function, you can improve the readability and maintainability of your PHP code while simplifying the cURL configuration process. With examples, developers can efficiently handle network requests in PHP.

This article provides an in-depth explanation of the PHP curl_init() function, helping you quickly master how to initialize and manage cURL sessions. Through detailed example code, you will learn how to send HTTP requests and handle response data, improving your development efficiency for server communication in PHP.

This article explains how to use the curl_error() function in PHP to retrieve error messages from cURL requests, helping developers quickly diagnose and resolve issues with network requests. We will demonstrate how to effectively use curl_error() to handle errors in requests and improve debugging efficiency.

This article introduces the curl_errno() function in PHP, which helps developers retrieve cURL request error codes. Through example code, it demonstrates how to use curl_errno() to capture and handle common network request errors, such as connection timeouts and host resolution failures, offering practical error-handling solutions for PHP developers.

This article provides a comprehensive guide on how to use PHP's CURL extension to perform remote data fetching, including GET and POST request handling, error management, and timeout configuration. Clear code examples are included to help developers efficiently master data scraping techniques.

cURL is a very powerful library for sending HTTP requests and getting remote data. Typically, each cURL request needs to be independently initialized and configured, but in some cases, sharing certain resources (such as connections, sessions, etc.) between multiple requests can greatly improve performance. At this time, the curl_share_init() function comes in handy. It can share some resources between multiple cURL requests, thereby reducing the overhead of repeated connection establishment and improving the efficiency of requests.

cURL is a powerful library that allows us to send HTTP requests and get responses. The curl_share_init() function is a mechanism provided by cURL to initialize shared cURL handles. Share a cURL handle, multiple cURL sessions can share some configuration options and data, which can reduce memory consumption and improve the efficiency of multiple cURL sessions.

How to use curl's verbose mode to observe the execution behavior and debugging information of the curl_upkeep() function?

In PHP, the hash_update_stream function is a method for dynamically updating hash values, especially when processing stream data. Combined with curl, it can realize the hash value calculation in real time when downloading large files or streaming data. In this article, we will explore how to use hash_update_stream and curl to achieve this.

The commonly used way to send HTTP requests is to use cURL, but we can also use the stream_context_get_options() function to replace cURL to implement the sending of POST requests. stream_context_get_options() is a function in PHP that gets all options for the current stream context, and it can be used with file_get_contents() to allow us to send requests over the HTTP protocol.

In daily PHP development, we often need to obtain XML data from remote servers and parse it. This article will demonstrate how to use curl to download XML data, then parse the content with the xml_parse series of functions, and convert it to an available array structure.
