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

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:
