Return a single line from a file, stream or socket, with optional size limit
This function works with different resource types. If no size is specified, it will keep reading from the file, stream or socket until it reaches the end of the line (or the end of the file). For streams and sockets it will return characters until a line feed (LF) or carriage return (CR) is reached (it will wait until an entire line is received). If the optional size is specified and the line is longer than this size, the function will return only the number of characters specified.
$handle: Valid handle of a previously opened resource
$size: Optional limit to the number of bytes returned
