php-guzzlePHP Guzzle post request example

Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and trivial to integrate with web services. Here is an example of a POST request using Guzzle:

<?php
$client = new GuzzleHttp\Client();
$res = $client->request('POST', 'http://httpbin.org/post', [
    'form_params' => [
        'field_name' => 'abc',
        'other_field' => '123',
        'nested_field' => [
            'nested' => 'hello'
        ]
    ]
]);
echo $res->getStatusCode();
// 200
echo $res->getHeaderLine('content-type');
// 'application/json; charset=utf8'
echo $res->getBody();
// '{"type":"User"...'
?>

The code above will send a POST request to the URL http://httpbin.org/post with the form parameters field_name, other_field, and nested_field. The response will be a status code of 200 and a content-type header of application/json; charset=utf8. The body of the response will be a JSON string.

Code explanation

1. $client = new GuzzleHttp\Client(); - This creates a new Guzzle client object.
2. $res = $client->request('POST', 'http://httpbin.org/post', [ - This sends a POST request to the URL http://httpbin.org/post with the form parameters.
3. 'form_params' => [ - This is the array of form parameters that will be sent with the request.
4. echo $res->getStatusCode(); - This will output the status code of the response.
5. echo $res->getHeaderLine('content-type'); - This will output the content-type header of the response.
6. echo $res->getBody(); - This will output the body of the response.
