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.

- "CURLINFO_TOTAL_TIME" - El tiempo total de transacción en segundos para la última transferencia
- "CURLINFO_NAMELOOKUP_TIME" - El tiempo en segundos transcurrido hasta que la resolución de nombres fue completada
- "CURLINFO_CONNECT_TIME" - El tiempo en segundos que se tardó en establecer la conexión
- "CURLINFO_PRETRANSFER_TIME" - El tiempo en segundos transcurrido desde el comienzo hasta antes de comenzar la transferencia
- "CURLINFO_STARTTRANSFER_TIME" - El tiempo en segundos transcurrido hasta que el primer byte está listo para ser transferido
- "CURLINFO_REDIRECT_TIME" - El tiempo en segundos de todos los redireccionamientos previos a la transacción final
- "CURLINFO_SIZE_UPLOAD" - Número total de bytes enviados
- "CURLINFO_SIZE_DOWNLOAD" - Número total de bytes recibidos
- "CURLINFO_SPEED_DOWNLOAD" - Velocidad promedio de recepción
- "CURLINFO_SPEED_UPLOAD" - Velocidad promedio de envío
- "CURLINFO_HEADER_SIZE" - Tamaño total de todos los encabezados recibidos
- "CURLINFO_REQUEST_SIZE" - Tamaño total de las peticiones efectuadas, actualmente solo para peticiones HTTP
- "CURLINFO_SSL_VERIFYRESULT" - Resultado de la verificación de certificado SSL requerida al indicar CURLOPT_SSL_VERIFYPEER

- "request_size"
- "filetime"
- "ssl_verify_result"
- "redirect_count"

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.

<?php

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 {

curl_close($ch); // close cURL handler
if (empty($info['http_code'])) {

} else {
// load the HTTP codes
$http_codes = parse_ini_file("path/to/the/ini/file/I/pasted/above");

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:
