I am trying to get image size using

get_headers($url)

But I am getting warning like 

get_headers() [function.get-headers]: http:// wrapper is disabled in the server configuration by allow_url_fopen=0 in

Is there any other way to Do so?

Thanks.

You can use curl_getinfo() function to get the remote file size.

 $ch = curl_init('http://www.google.co.in/images/srpr/logo4w.png');

 curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
 curl_setopt($ch, CURLOPT_HEADER, TRUE);
 curl_setopt($ch, CURLOPT_NOBODY, TRUE);

 $data = curl_exec($ch);
 $size = curl_getinfo($ch, CURLINFO_CONTENT_LENGTH_DOWNLOAD);

 curl_close($ch);
 echo $size;

You must perform a HEAD request. This will tell the server that you're only interested in the HTTP headers.

stream_context_set_default(
    array(
        'http' => array(
            'method' => 'HEAD'
        )
    )
);
$headers = get_headers('http://example.com');

This will return an array of headers. You must find the content-length item which has the file size (number of bytes).
