Need help with fsockopen()

I have a script that downloads html pages from many different sites. The script executes as expected but is sloooooooow. I would like to replace fopen() with fsockopen() so that I can set a time limit for the page downloads. Here is an example of how I'm using fopen(): $OpenFile = fopen("$site_url", 80); //$site_url = www.domainname.com/complete/path/to/the/page.htm $getFile = fread($OpenFile, 50000); Simply put, how do I do the exact same thing as above with fsockopen(). Thanks, Cliff
