Возвращает информацию о последней операции, opt может быть одной из следующих констант:

  • CURLINFO_EFFECTIVE_URL - Последний использованный URL
  • CURLINFO_HTTP_CODE - Последний полученный код HTTP
  • CURLINFO_FILETIME - Дата модификации загруженного документа, если она неизвестна, возвращается -1.
  • CURLINFO_TOTAL_TIME - Полное время выполнения операции в секундах.
  • CURLINFO_NAMELOOKUP_TIME - Время разрешения имени сервера в секундах.
  • CURLINFO_CONNECT_TIME - Время, затраченное на установку соединения, в секундах
  • CURLINFO_PRETRANSFER_TIME - Время, прошедшее от начала операции до готовности к фактической передаче данных, в секундах
  • CURLINFO_STARTTRANSFER_TIME - Время, прошедшее от начала операции до момента передачи первого байта данных, в секундах
  • CURLINFO_REDIRECT_TIME - Общее время, затраченное на перенапрвления, в секундах
  • CURLINFO_SIZE_UPLOAD - Количество байт при закачке
  • CURLINFO_SIZE_DOWNLOAD - Количество байт при загрузке
  • CURLINFO_SPEED_DOWNLOAD - Средняя скорость закачки
  • CURLINFO_SPEED_UPLOAD - Средняя скорость загрузки
  • CURLINFO_HEADER_SIZE - Суммарный размер всех полученных заголовков
  • CURLINFO_REQUEST_SIZE - Суммарный размер всех отправленных запросов, в настоящее время используется только для HTTP запросов
  • CURLINFO_SSL_VERIFYRESULT - Результат проверки SSL сертификата, запрошенной с помощью установки параметра CURLOPT_SSL_VERIFYPEER
  • CURLINFO_CONTENT_LENGTH_DOWNLOAD - размер загруженного документа, прочитанный из заголовка Content-Length
  • CURLINFO_CONTENT_LENGTH_UPLOAD - Размер закачиваемых данных
  • CURLINFO_CONTENT_TYPE - Содержимое полученного заголовка Content-type, или NULL в случае, когда этот заголовок не был получен

При вызове без необязательного аргумента opt возвращается ассоциативный массив со следующими индексами, которые соответствуют значениям аргумента opt :

A code snippet that I had attempted to enumerate the Remote File Size and to post Amount of Time taken for that particular Curl Request.

<?php

/* borrowed the Byte Conversion code (byte_convert function) posted by "olafurw at gmail.com" and modified by "d.abromeit" in http://in.php.net/filesize. I did make changes in the notation of expression of multiples of bytes from KiB => KB, MiB => MB etc all symbols in this Byte Code*/

 
function byte_convert($bytes)
  {
   
$symbol = array('B', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB');

   
$exp = 0;
   
$converted_value = 0;
    if(
$bytes > 0 )
    {
     
$exp = floor( log($bytes)/log(1024) );
     
$converted_value = ( $bytes/pow(1024,floor($exp)) );
    }

    return
sprintf( '%.2f '.$symbol[$exp], $converted_value );
  }

  
$userAgent = 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)';
  
$url = 'http://www.spiderace.com/samplefiles/testfile.zip';

   
// initialize curl with given url
   
$ch = curl_init($url);
   
// make sure we get the header
   
curl_setopt($ch, CURLOPT_HEADER, 1);
   
// make it a http HEAD request
   
curl_setopt($ch, CURLOPT_NOBODY, 1);
   
// add useragent
   
curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
   
//Tell curl to write the response to a variable
   
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   
// The maximum number of seconds to allow cURL functions to execute.
   
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,60);
   
// Tell curl to stop when it encounters an error
   
curl_setopt($ch, CURLOPT_FAILONERROR, 1);
   
   
$execute = curl_exec($ch);
   
   
// Check if any error occured
   
if(!curl_errno($ch))
    {
       
$bytes = curl_getinfo($ch, CURLINFO_CONTENT_LENGTH_DOWNLOAD);
       
// Display the File Size
       
echo byte_convert($bytes);
        echo
"<br><br>";
       
$total_time = curl_getinfo($ch, CURLINFO_TOTAL_TIME);
        echo
'Took ' . $total_time . ' seconds to send a request to ' . $url;
       
clearstatcache();
    }
   
curl_close($ch);

?>

NOTE: This code worked on Both Linux (tried on CentOS) & Windows Servers (tried on XAMPP For Windows on Windows XP PC), thank you. Hope this will be helpful to others as well.

CURLINFO_CONTENT_LENGTH_DOWNLOAD contains zero in FTP request although Content-Length field is present.

Following workaround may helps:

<?php
$ch
= curl_init($url);
...
CURL OPTIONS ...
$result=curl_exec($ch);
$pu=parse_url($url);
if(
$pu['scheme']=='ftp'){
   
$regexp="/Content-Length: (\d*)/";
   
preg_match($regexp,$result,$matches);
   
$con_len=$matches[1];
}
else
$con_len = curl_getinfo($ch, CURLINFO_CONTENT_LENGTH_DOWNLOAD);
?>

Its worth to keep using CURLINFO_CONTENT_LENGTH_DOWNLOAD in http requests, becouse there could be several headers pack if CURLOPT_FOLLOWLOCATION is fired, and regular expression for this case is a little bit complicated.

Just a quick note: if you want to use curl_getinfo() with option CURLINFO_HEADER_OUT in order to debug your cURL request, you must add curl_setopt($handle, CURLINFO_HEADER_OUT, true); first while specifying the options.

Keep in mind that for CURLOPT_RETURNTRANSFER it has to be set with curl_setopt() before execution:

This doesn't work:
<?php
$ch
= curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_exec($ch);
var_dump(curl_getinfo($ch,CURLINFO_HEADER_OUT));
?>

This works:
<?php
$ch
= curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_exec($ch);
var_dump(curl_getinfo($ch,CURLINFO_HEADER_OUT));
?>

There is a constant missing from that list.  CURLINFO_REDIRECT_COUNT will give you the number of redirects it went through if CURLOPT_FOLLOWLOCATION was set.

Here are the response codes ready for pasting in an ini-style file. Can be used to provide more descriptive message, corresponding to 'http_code' index of the arrray returned by curl_getinfo().
These are taken from the W3 consortium HTTP/1.1: Status Code Definitions, found at
http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html

[Informational 1xx]
100="Continue"
101="Switching Protocols"

[Successful 2xx]
200="OK"
201="Created"
202="Accepted"
203="Non-Authoritative Information"
204="No Content"
205="Reset Content"
206="Partial Content"

[Redirection 3xx]
300="Multiple Choices"
301="Moved Permanently"
302="Found"
303="See Other"
304="Not Modified"
305="Use Proxy"
306="(Unused)"
307="Temporary Redirect"

[Client Error 4xx]
400="Bad Request"

500="Internal Server Error"
501="Not Implemented"
502="Bad Gateway"
503="Service Unavailable"

505="HTTP Version Not Supported"

And an example usage:
<?php
$ch
= curl_init(); // create cURL handle (ch)
if (!$ch) {
    die(
"Couldn't initialize a cURL handle");
}
// set some cURL options
$ret = curl_setopt($ch, CURLOPT_URL,            "http://mail.yahoo.com");
$ret = curl_setopt($ch, CURLOPT_HEADER,         1);
$ret = curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$ret = curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
$ret = curl_setopt($ch, CURLOPT_TIMEOUT,        30);

// execute
$ret = curl_exec($ch);

if (empty(
$ret)) {
   
// some kind of an error happened
   
die(curl_error($ch));
   
curl_close($ch); // close cURL handler
} else {
   
$info = curl_getinfo($ch);
   
curl_close($ch); // close cURL handler

   
if (empty($info['http_code'])) {
            die(
"No HTTP code was returned");
    } else {
       
// load the HTTP codes
       
$http_codes = parse_ini_file("path/to/the/ini/file/I/pasted/above");
       
       
// echo results
       
echo "The server responded: <br />";
        echo
$info['http_code'] . " " . $http_codes[$info['http_code']];
    }

}
?>

You can get some documentation about what these values mean in the libcurl C API documentation here:
