Reading in contents of URL

I am trying to create a really simple proxy using PHP. Basically, i need to: 1. read in the contents of a URL. 2. get the content-type 3. set the content type for the response 4. write the contents of the URL to the response. here is what i have thus far: $dataURL = "http://www.foo.com/data.xml"; $fp = fopen($dataURL, "r"); $content = fread($fp, true); echo($content); fclose($fp); I am running into two problems. One, the second param for fread takes the size of the file / content. how do i get this? 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? thanks for any help... mike c mesh@speakeasy.org
