You need to have the cURL extension, with which you can make an HTTP HEAD request to the remote server. The answer will let you know how big the file is.

Example:

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_HEADER, true); 
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
curl_setopt($ch, CURLOPT_URL, $url); //specify the url
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
$head = curl_exec($ch);

$size = curl_getinfo($ch,CURLINFO_CONTENT_LENGTH_DOWNLOAD);

if(<limit the $size>){
    file_get_contents($url);
}
