// Initialize cURL $curl = curl_init(); // Set API endpoint URL $url = "https://api.example.com/data"; // Set options for cURL request curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // Execute request and store response $response = curl_exec($curl); // Close cURL connection curl_close($curl); // Process response data $data = json_decode($response, true);This example demonstrates how to use cURL to retrieve data from an API endpoint and process it in a PHP application. The code initializes a cURL connection, sets the endpoint URL, executes the request, stores the response, and closes the connection. The response data is then processed using the `json_decode` function. This module is built into the core PHP language and does not require any external package library.
