rest - How to debug a get request in php using curl -

i'm trying make request in php using curl. i'm doing:

$curl = curl_init();  curl_setopt($curl, curlopt_httpauth, curlauth_basic); curl_setopt($curl, curlopt_userpwd, "username:password");  curl_setopt($curl, curlopt_url, $url); curl_setopt($curl, curlopt_returntransfer, 1);  $result = curl_exec($curl); curl_close($curl);  printf($result); 

but $result doesn't print out anything, no success or failure message. i've reached endpoint via postman , in web browser know works. printing out $curl prints: "resource #1" makes me think curl installed on server.

i'm not sure steps take next make things work.

add few more option troubleshooting purposes.

check error response.

if no error, details:

curl_setopt($ch, curlopt_connecttimeout, 10); curl_setopt($ch, curlopt_timeout,10); curl_setopt($ch, curlopt_failonerror,true); curl_setopt($ch, curlopt_encoding,"");  curl_setopt($ch, curlopt_verbose, true); curl_setopt($ch, curlinfo_header_out, true); curl_setopt($ch, curlopt_header, true);  $data = curl_exec($ch); if (curl_errno($ch)){     $data .= 'retreive base page error: ' . curl_error($ch); } else {   $skip = intval(curl_getinfo($ch, curlinfo_header_size));    $head = substr($data,0,$skip);   $data = substr($data,$skip);   $info = curl_getinfo($ch);   $info = var_export($info,true); } echo $head; echo $info;
