Example of using the curl_setopt() function to set the HTTP method and the data to be sent as JSON in PHP
<?php
$data = ['key' => 'value'];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://example.com/resource");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json', 'Content-Length: ' . strlen(json_encode($data))]);
$result = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error: ' . curl_error($ch);
}
curl_close($ch);You can change the method to POST or GET. Note that for GET requests in PHP, you should remove CURLOPT_POSTFIELDS and the Content-Length header, as GET requests do not send a request body.
