PHP Curl for Rest API not working

Question

This works fine directly in bash:

curl https://test.url.com/api/id/98765 -H 'API_KEY: xxxxxxxxxx' -H 'Authorization: Basic xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx=='

This does not work in PHP (nothing is returned):

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL,'https://test.url.com/api/id/98765');
curl_setopt($curl, CURLOPT_HEADER, 1);
curl_setopt($curl, CURLOPT_HTTPHEADER,  array(
                                            "API_KEY: xxxxxxxxxx8",
                                            "Authorization: Basic xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx=="
                                            ));         
curl_setopt($curl, CURLOPT_RETURNTRANSFER,1);
curl_setopt($curl, CURLOPT_VERBOSE, 1);
$results = curl_exec($curl);
echo 'out: '.$results;

No errors are returned. I'm expecting results in json

yes, error reporting is on. I tested by deliberately creating a syntax error — user2029890

Blat! Nevermind, now I see that you have it working in CURL. *Goes and digs deeper* — brandonscript

Can you try adding curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);? — brandonscript

Is the request getting sent at all? If yes, what exactly is getting sent? — ragol

Hazarding a guess (and we ultimately determined this to be true) that you need:

curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);

(note that 0 is synonymous with false).

This stops the client from verifying the SSL certificate of the remote location. I suggested this because your url is on https:// but it looks like a custom built solution which you likely don't have a public trusted cert configured for it (yet).

More information on CURLOPT_SSL_VERIFYPEER is available in the php docs.

The following PHP code is working for me fine to a renowned API. Here i have to implement CURLOPT_SSL_VERIFYPEER and CURLOPT_USERAGENT. you can try with this

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "https://testurl.com/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 15);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);

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