One, the second param for fread takes >the size of the file / content. how do i get this? You don't. Actually, if you can get the headers, and *IF* the headers are kosher enough to tell you the Content-length:, and if that number is actually correct, you would know how many bytes. *BUUUUUT* I sure wouldn't trust every web-server on the planet to correctly output the Content-length: anyway, so that's out. Your choices are: 1. Use http://php.net/eof and a loop to figure out when there's no more HTML coming. 2. Assume every URL has a reasonable amount of data and just use http://file >there is a comment at: >http://www.php.net/manual/en/function.fread.php > >which says to just specify a constant and it will work, but what ever >number i specify, that is the amount of data that is read. > >how do i retrieve the content type? Assuming you're not running 4.3.0 from CVS and http://www.php.net/manual/en/function.file_get_wrapper_data.php is not helpful, you're stuck with doing something like this: <?php $sock = fsockopen('example.com', 80) or die("Could not open socket to example.com"); fputs($sock, "GET /whatever.html HTTP/1.0"); # Might need \n on the end... fputs($sock, "Host: example.com"); # In case it's virtual hosting. fputs($sock, ""); # MUST send blank line before output will occur! # The end of headers is indicated by a blank line: $inheaders = true; $headers = ''; while ($inheaders && !feof($sock)){ $line = fgets($sock, 4096); # Any header over 4K in length will screw this up... if ($line){ $headers .= $line; # You could also parse the headers looking for Content-type: and so on. # But you should *NEVER* assume that other stupid web-server is going to bother to tell you... # Much less tell you correctly. # If it doesn't say, it's supposed to be text/plain... # But stupid IE looks at the URLs and uses them anyway, so Good Luck! } else{ $inheaders = false; } } $content = ''; while (!feof($sock)){ $content .= fread($sock, 4096); # If you expect to suck down HUGE pages, increase this... } ?> -- Like Music? http://l-i-e.com/artists.htm I'm looking for a PRO QUALITY two-input sound card supported by Linux (any major distro). Need to record live events (mixed already) to stereo CD-quality. Soundcard Recommendations? Software to handle the recording? Don't need fancy mixer stuff. Zero (0) post-production time. Just raw PCM/WAV/AIFF 16+ bit, 44.1KHz, Stereo audio-to-disk.
