How to get PHP cURL info such as execute time and number of HTTP request made

i am trying to calculate

1. No of HTTP request made by cURL to example.com
2. Total time taken for cURL to get string from example.com
3. No of Redirect count.

Code :

function file_get_contents_curl($url) {
    $agent = $_SERVER['HTTP_USER_AGENT'];
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);   
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_USERAGENT, $agent);   
    curl_setopt($ch, CURLOPT_VERBOSE, true);

    // Get the content type
    curl_setopt($ch, CURLOPT_NOBODY, 1);
    curl_exec($ch);
    $content_type = curl_getinfo($ch, CURLINFO_CONTENT_TYPE);

    // Get the content
    curl_setopt($ch, CURLOPT_NOBODY, 0);
    $data = curl_exec($ch);
    
    // Stats 
    $http_request = curl_getinfo($ch, CURLINFO_NUM_CONNECTS);
    $total_time = curl_getinfo($ch, CURLINFO_TOTAL_TIME);
    $request_count = curl_getinfo($ch, CURLINFO_REDIRECT_COUNT) + 1;
    $connect_time = curl_getinfo($ch, CURLINFO_CONNECT_TIME);
    curl_close($ch); 

    // Set the content type header
    header('Content-Type:' . $content_type);

    echo "HTTP Request: " . $http_request . "<br>";
    echo "Total Time: " . $total_time . "<br>";
    echo "Redirect count: " . $request_count . "<br>";
    echo "Connection time: " . $connect_time . "<br>";

    return $data;
}

$homepage = file_get_contents_curl("https://example.com");
echo $homepage;

Error : $http_request value returning 0
