The php Function Curl_Share_Init

Functions are one of the most powerful tools available in PHP. They let you write code that is modular and reusable. There are many functions built into PHP, as well as extensions that can be compiled with the language, and you can also create your own. Functions are used to perform an action against multiple items or locations within a program, and you can pass information to them through arguments.

The php function curl_share_init() allows you to share data between multiple cURL handles. You can use this function to share DNS cache, Cookie data, or SSL session IDs. Using this function will allow you to reduce the amount of time spent on SSL handshakes. This is especially helpful when simulating frequent ajax calls to the same set of URLs.

Curl is a popular library for working with Internet protocols such as HTTP, FTP and SFTP. Its versatility makes it a useful tool for a variety of tasks, including transferring data between servers and testing APIs.

Prior to PHP 8, the curl init functions (curl_init, curl_multi_init and curl_share_init) returned a PHP resource type. These were then transformed into class objects in PHP 8. This move was part of the Resource to Object migration plan, and will not cause backwards incompatibilities for any existing code that uses these functions. However, since the new functions return objects instead of PHP resources, the is_resource function will no longer be able to tell if they were created successfully.
