curl_exec
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.

}
// set some cURL options
$ret = curl_setopt($ch, CURLOPT_URL, "http://mail.yahoo.com");

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