Sending JSON Data with Curl in PHP: GET, PUT, POST, and DELETE

Introduction

Curl is a versatile tool for making HTTP requests and working with web APIs. In PHP, you can leverage Curl to pass JSON data through various HTTP methods like PUT, POST, GET, and DELETE.

Passing JSON through PUT

$data = ['username' => 'dog', 'password' => 'tall'];
$data_json = json_encode($data);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json', 'Content-Length: ' . strlen($data_json)]);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

Passing JSON through POST

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

Passing JSON through GET

As mentioned in the question, adding JSON data to a GET request is not typically done in the URL. This is because GET requests are traditionally used to fetch resources without modifying them.

Passing JSON through DELETE

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'DELETE');
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
