curl_exec returns unreadable text - cURL PHP-CodePudding

I am trying cURL, but curl_exec() returns unreadable text like the screenshot below. I wrote cURL like below. I was wondering how to fix this issue.

$ch = curl_init("https://app.kajabi.com/login");
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Host: app.kajabi.com',
    'Connection: keep-alive',
    'Cache-Control: max-age=0',
    'sec-ch-ua: " Not A;Brand";v="99", "Chromium";v="99", "Google Chrome";v="99"',
    'sec-ch-ua-mobile: ?0',
    'sec-ch-ua-platform: "Windows"',
    'Upgrade-Insecure-Requests: 1',

));
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);

if (curl_errno($ch)) {
    print "Error: " . curl_error($ch);
    exit();
}
echo $response;

CodePudding user response：

I tried putting the response into a file, and it appears that the response is in gzip format. file_put_contents('temp.gz',$response)

I extracted the archive and found that it's a HTML document telling you that the access is denied.

You can show the response directly in the output of your php script, though:

$decoded_response = gzdecode($response);
echo $decoded_response;

And maybe you should check whether the content is actually gzip before attempting to use gzdecode; see this thread: php curl, detect response is gzip or not

Edit: You can let php automatically do the decoding by setting CURLOPT_ENCODING to '':
