feof doesn't work on remote fgets call

The following code snippet works great, with one slight problem....

if(!($File=@fopen($url,"r")))  // $url = http://www.somedomain.com/somepage.htm?var1=var
{ echo "couldn't read $url "; exit; }

while (!feof($File)) {

The page I'm retrieving is just a plain html table with roughly 20 rows, but the last few characters are always missing. I've tried various line sizes, but still get the same results.  According to a note in the PHP manual, you can't look for feof on a remote file, which seems to be the cause of the missing characters.  

How could the above snippet be re-written to not use feof, and hopefully, not drop the last few characters?

why not swap

while (!feof($File)) {


$contents = "";
do {
    $data = fread($File, 8192);
    if (strlen($data) == 0) {
    $contents .= $data;
} while(true);

Im a bit embarresed here. I tried lozloz solution and was amazed that it didn't give me different results...
Turns out the whole problem was just below the code posted above...

$start_position=strpos($Line, $start);
$end_position=strpos($Line, $end)+strlen($end);
$Line=substr($Line, $start_position, $length);

because $end did not equal any part $Line , the last line was dropped. I surrounded that block with an if, so if $url had a particular substring, the start/end block above wasn't executed.. it now works perfectly with either my or lozoz's code.
