Numerical zero value (0) returned as empty cell

If a cell contains a numerical zero value, i.e. 0, the cell is return as an empty cell of zero length.

I think this is because of a bug in phpexcel.inc::phpexcel_import($path, $keyed_by_headers = TRUE).

All instances of:

$value = $cell->getValue() ? $cell->getValue() : '';

will return an incorrect '' for a value of 0 (zero).
