PHP cURL HTTP PUT | Complete Guide to Sending PUT Requests in PHP

If you are looking to send a HTTP PUT request using PHP cURL, then you have come to the right place. In this guide, we will provide a complete explanation on how to send PUT requests in PHP using cURL.

Firstly, we need to understand what a PUT request is. A PUT request is a method of sending data to a server to update or create a resource at a specific URL. This is different from a POST request, which is typically used to create a new resource.

To send a PUT request in PHP using cURL, we need to use the CURLOPT_CUSTOMREQUEST option in the curl_setopt function. This option allows us to specify the HTTP method we want to use, in this case "PUT". We also need to set the CURLOPT_POSTFIELDS option to the data we want to send in the request.

Here is an example of how to send a PUT request using PHP cURL:


$url = "https://example.com/resource/123";
$data = array("name" => "John", "age" => 30);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
curl_close($ch);

In this example, we are sending a PUT request to update the resource at URL "https://example.com/resource/123" with the data array containing the name and age.

In conclusion, sending a HTTP PUT request in PHP using cURL is a straightforward process. By using the CURLOPT_CUSTOMREQUEST and CURLOPT_POSTFIELDS options, we can easily send PUT requests and update or create resources on a server.
