How to perform a cURL PUT request in PHP?

To perform a cURL PUT request in PHP, you can use the following code:

<?php

$url = '<url>'; // Replace with the URL you want to send the PUT request to

$data = array(
    'key1' => 'value1',
    'key2' => 'value2'
); // Replace with your desired data to be sent

$ch = curl_init($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);

// Print the response
echo $response;
?>

Make sure to replace <url> with the actual URL you want to send the PUT request to. Also, replace the $data array with your desired data to be sent as a JSON payload.

This code sets the request method to PUT using curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT') and the data to be sent using curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data)). Finally, the response is captured using curl_exec($ch) and printed using echo $response.
