curl
Here I'm using curl to verify a list of link (avi/mpg) to be sure there is not 404.
what I do is
$ch = curl_init ($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$result2 = curl_exec ($ch);
curl_close ($ch);
print $result2;
and verify that they have the Content-Type: video/x-msvideo header
but how to stop curl from downloading the whole avi/mpg ?!
I just want the headers

yeah.. but it takes for ever to check like 10 of them!
maybe there is a way to do it with socket function?!
Please advise!

8192 is number of bytes, its 8k basically. You can keep it to say 4096 - 4k.
It means data will be read in 4k chunk from socket.

and 4k is enough to cover the headers ?
how do I tell to read just the first 4k ?

replace existing $line...with
$line = fgets($fp,4096); //it should read 4k.
And yeah it will suffice though try and test it. thats the best way !!
