PHP cURL Error

[nolanmaris]

Hello

I am facing an issue with cURL in my PHP application. When trying to make a secure HTTPS request, I am getting the following error:

cURL error: SSL certificate problem: unable to get local issuer certificate

Details:

• Server Environment: Apache on Ubuntu 20.04
• PHP Version: 7.4
• cURL Version: 7.68.0

Code Snippet

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.example.com/data");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
if (curl_errno($ch)) {
echo 'cURL error: ' . curl_error($ch);
}
curl_close($ch);


I haveverified that the SSL certificate is valid and not expired. Downloaded and updated the cacert.pem file from cURL's website and configured php.ini:


curl.cainfo = "/path/to/cacert.pem"

Checked the server's openssl version and it is up-to-date.

How can I resolve the "unable to get local issuer certificate" error in cURL?
Are there any additional configurations I need to make in php.ini or my server environment?

Any suggestions on how to solve this SSL issue would be greatly appreciated.



Thank you in advance for your help!
