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.
