fread() does not return error (false) on read out of file, returns "" (empty string)

Test script:
---------------
$f = fopen("file","r"); // file must be several KBytes size
$page = 0;
while ( !fseek($f,$page,SEEK_SET) )
{
   $page += 1024;
   $str = fread($f,1024);
   if ( $str === false )
      die("error reading block");
}

echo "ok"

----------------
fread should return false

Actual result:
--------------

Pageoff = 75776 fseek=0 ftell=75776 read=1024 string
Pageoff = 76800 fseek=0 ftell=76800 read=0 string
Pageoff = 77824 fseek=0 ftell=77824 read=0 string
