PHP 8.2 - Unexpectedly Empty Response from cURL When Sending JSON Data
I'm stuck on something that should probably be simple. I've spent hours debugging this and I need some guidance on I'm relatively new to this, so bear with me... I'm experiencing an scenario with cURL in PHP 8.2 when trying to send a JSON payload to an API endpoint. The request seems to be processed without behavior, but the response is consistently empty. Here's a simplified version of my code: ```php $url = 'https://api.example.com/data'; $data = json_encode(['key' => 'value']); $ch = curl_init($url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); $response = curl_exec($ch); if ($response === false) { echo 'cURL behavior: ' . curl_error($ch); } else { echo 'Response: ' . $response; } curl_close($ch); ``` I have verified that the API endpoint is correct and functional by testing it with Postman, where it returns the expected data. When I run the above PHP code, I see no errors, but the output is always `Response:` followed by nothing. I also tried using `curl_getinfo($ch)` to get additional information about the request, which shows a `HTTP Code` of `200` but still no body in the response. I made sure that `allow_url_fopen` is enabled in my `php.ini`, and the server has cURL installed. I also checked for any server-side logs that might indicate why the response is empty, but came up with nothing. Any suggestions on what could be causing this scenario? I'm exploring on this for a few days now, and I would appreciate any insights or debugging tips. My team is using Php for this CLI tool. Hoping someone can shed some light on this. I'm working in a Windows 10 environment. I'm open to any suggestions. My development environment is Linux. Has anyone else encountered this?
