I'm experiencing weird behaviour of a cURL request that I do in my PHP code. I'm running the code locally on a standard WAMP Apache server. Here's the code:

$auth_info = "...";
$some_url = "...";
$channel = curl_init();
curl_setopt($channel, CURLOPT_URL, $some_url);
curl_setopt($channel, CURLOPT_HTTPHEADER, 
    array("Authorization: BASIC " . base64_encode($auth_info))
curl_setopt($channel, CURLOPT_RETURNTRANSFER, true);
curl_setopt($channel, CURLOPT_HEADER, true);
$response = curl_exec($channel);
$header_size = curl_getinfo($channel, CURLINFO_HEADER_SIZE);
$header = substr($response, 0, $header_size);
$body = substr($response, $header_size);

If I'm executing this little PHP code snippet via my CLI (Powershell, since I'm running on Windows), everything is fine, all var_dumps work and I can see the $header and $body and everything and the data I expect is actually present.

Now for the weird behaviour. If I'm opening the script file with the above snippet in any browser, it just gives me:

array (size=26)
'url' => string 'the_url_here' (length=39)
'content_type' => null
'http_code' => int 0
'header_size' => int 0
'request_size' => int 0
'filetime' => int -1
'ssl_verify_result' => int 0
'redirect_count' => int 0
'total_time' => float 1.234
'namelookup_time' => float 0
'connect_time' => float 0.109
'pretransfer_time' => float 0
'size_upload' => float 0
'size_download' => float 0
'speed_download' => float 0
'speed_upload' => float 0
'download_content_length' => float -1
'upload_content_length' => float -1
'starttransfer_time' => float 0
'redirect_time' => float 0
'redirect_url' => string '' (length=0)
'primary_ip' => string 'here_is_the_ip' (length=12)
'certinfo' => 
  array (size=0)
'primary_port' => int 443
'local_ip' => string 'here_is_my_ip' (length=13)
'local_port' => int -> my_local_port_here
boolean false
boolean false

I'm completely puzzled since I cannot see a difference between the script beeing started by the CLI and beeing started by the browser. Has anyone got an idea on this?

EDIT Note: If I'm using Guzzle for the request, everything works fine, both in CLI and browser. I'm still interested in an answer why cURL is causing problems here.

    Have you tried logging verbose output for the Curl request?

    Normally I find this the best way to figure out what's going on under the hood...

    Also not as popular but this approach looks simple to implement and is a lot cleaner...
