Curl not returning content length header

Trying to get the size of an image file using curl but the content length header is not returning:

$url ="http://www.collegefashion.net/wp-content/plugins/feed-comments-number/image.php?1263";
$fp = curl_init();
curl_setopt($fp, CURLOPT_NOBODY, true);
curl_setopt($fp, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($fp, CURLOPT_FAILONERROR,1);
curl_setopt($fp, CURLOPT_REFERER,'');
curl_setopt($fp, CURLOPT_URL, $url);
curl_setopt($fp, CURLOPT_HEADER,1);
curl_setopt($fp, CURLOPT_USERAGENT,'Mozilla/5.0');
$body = curl_exec($fp);

var_dump ($ body):

HTTP/1.1 200 OK

It works via ssh:

curl -i http://www.collegefashion.net/wp-content/plugins/feed-comments-number/image.php?1263

CURLOPT_NOBODY makes a HEAD request, while your command line with -i is a GET request ...



If you use -I with your version on the command line, they will be more similar.

Note : curl_getinfo() 

$size = curl_getinfo($fp, CURLINFO_CONTENT_LENGTH_DOWNLOAD);


Execute it after curl_exec()

.

Another parameter is set CURLOPT_HEADER

to false

and just dostrlen($body)

- ignore this, I didn't notice what you were using CURLOPT_NOBODY

.
