The file_get_contents() function is used to establish an HTTP connection and fetch the content of a web page. The curl_init() function provides more advanced features for handling HTTP requests, including support for various protocols and options. The fsockopen() function allows low-level socket programming for network communication. These functions enable PHP to interact with remote servers, retrieve data from APIs, perform HTTP requests, and handle network-related tasks.
