Description: ------------ In Lite.php line 638 $data = @fread($fp, $length); Comment from ------------------------------------- Somewhere between 4.2.3 and 4.3.9, the behaviour of fread() was changed slightly. When you ask to fread() 0 bytes of data, it spits out a warning (IMO for no good reason. I think reading 0 bytes is perfectly valid, if not very useful.) Consequently, to write warning-free code using fread, you'd have to take code like this: $content=fread($fd,filesize($myfile)); and replace it with this: $content=''; $length=filesize($myfile); if($length) { $content = fread($fd, $length); } ...or this, depending on your taste: $length=filesize($myfile); if($length) { $content = fread($fd, $length); } else { $content=''; } Reproduce code: --------------- Read an empty cache. Expected result: ---------------- No PHP warning if cache empty. Actual result: -------------- Produces a PHP Warning.
