How to make an HTTP request in PHP

There are several ways to make an HTTP request in PHP, including using the built-in file_get_contents() function, the cURL library, and various third-party libraries.

Here is an example of how to use file_get_contents() to make a GET request:

$url = 'https://example.com';
$response = file_get_contents($url);

Here is an example of how to use cURL to make a GET request:

$url = 'https://example.com';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);

You can also use cURL library to make a POST request, by adding the following options:

curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

where $data is an array of fields to be posted.

You can also use libraries like Guzzle for making HTTP requests.

use GuzzleHttp\Client;
$client = new Client();
$response = $client->get('https://example.com');
$response = $client->post('https://example.com', ['form_params' => $data]);

Please note that, these are just examples, you should check the documentation for more details and options.
