Save Excel 2010+ Functions Properly
For functions introduced in Excel 2010 and beyond, Excel saves them
in formulas with the xlfn_ prefix. PhpSpreadsheet does not do this;
as a result, when a spreadsheet so created is opened, the cells
which use the new functions display a #NAME? error.
This the cause of bug report 1246:
https://github.com/PHPOffice/PhpSpreadsheet/issues/1246
This change corrects that problem when the Xlsx writer encounters
a 2010+ formula for a cell or a conditional style. A new class
Writer/Xlsx/Xlfn, with 2 static methods,
is introduced to facilitate this change.
As part of the testing for this, I found some additional problems.
When an unknown function name is used, Excel generates a #NAME? error.
However, when an unknown function is used in PhpSpreadsheet:
- if there are no parameters, it returns #VALUE!, which is wrong
- if there are parameters, it throws an exception, which is horrible
Both of these situations will now return #NAME?
Tests have been added for these situations.
The MODE (and MODE.SNGL) function is not quite in alignment with Excel.
MODE(3, 3, 4, 4) returns 3 in both Excel and PhpSpreadsheet.
However, MODE(4, 3, 3, 4) returns 4 in Excel, but 3 in PhpSpreadsheet.
Both situations will now match Excel's result.
Also, Excel allows its parameters for MODE to be an array,
but PhpSpreadsheet did not; it now will.
There had not been any tests for MODE. Now there are.
The SHEET and SHEETS functions were introduced in Excel 2013,
but were not introduced in PhpSpreadsheet. They are now introduced
as DUMMY functions so that they can be parsed appropriately.
Finally, in common with the "rate" changes for which I am
creating a pull request at the same time as this one:
samples/Basic/13_CalculationCyclicFormulae
PhpUnit started reporting an error like "too much regression".
The test deals with an infinite cyclic formula, and allowed
the calculation engine to run for 100 cycles. The actual number of cycles
seems irrelevant for the purpose of this test. I changed it to 15,
and PhpUnit no longer complains.

- Fix loading styles from vmlDrawings when containing whitespace [#1347 ](https://github.com/PHPOffice/PhpSpreadsheet/issues/1347 )
Fix removing last row incorrect behavior
`$highestRow = $this->getHighestDataRow();` was calculated after `$this->getCellCollection()->removeRow($pRow + $r);` - this is the root reason for incorrect rows removal because removing last row will change '$this->getHighestDataRow()' value, but removing row from the middle will not change it. So, removing last row causes incorrect `$highestRow` value that is used for wiping out empty rows from the bottom of the table:
```php
for ($r = 0; $r < $pNumRows; ++$r) {
$this->getCellCollection()->removeRow($highestRow);
--$highestRow;
}
```
To prevent this incorrect behavior I've moved highest row calculation before row removal.
But this still doesn't solve another problem when trying remove non existing rows: in this case the code above will remove `$pNumRows` rows from below of the table, e.g. if `$highestRow=4` and `$pNumRows=6`, than rows 4, 3, 2, 1, 0, -1 will be deleted. Obviously, this is not good, that is why I've added `$removedRowsCounter` to fix this issue.
And finally, moved Exception to early if statement to get away from unnecessary 'if-else'.
Fixes #1364
Closes #1365
2020-04-26 02:00:43 +00:00
- Fix incorrect behavior when removing last row [#1365 ](https://github.com/PHPOffice/PhpSpreadsheet/pull/1365 )
MATCH with a static array should return the position of the found value based on the values submitted.
Returns #N/A, unless the element searched for is at the end of the array.
The problem is in Calculation.php line 4231:
if (!is_array($functionCall)) {
foreach ($args as &$arg) {
$arg = Functions::flattenSingleValue($arg);
}
unset($arg);
}
I believe this code is intended to handle functions where PhpSpreadsheet just passes
the call on to PHP without implementing the code on its own, e.g. for atan or acos.
In the bug report, the following code fails:
$flat_rate = "=MATCH(6,{4,5,6,2}, 0)";
$sheet->getCell('A1')->setValue($flat_rate);
The expected value is 3, but the actual result is "#N/A".
The reason for this result is that the parser replaces the braces with calls
to the MKMATRIX internal function, whose value for functioncall was:
'self::MKMATRIX'. Since this isn't an array, the flattening code is executed,
and the unintended result occurs. The fix is to change the definition for
functioncall in that case to [__CLASS__, 'mkMatrix'], avoiding the flattening.
However, there is also another part to this bug. The flattening should be
returning the first entry in the array, but is in fact returning the last.
This explains why the bug report specified "unless ... end of the array".
I confirmed that Excel does use the first item in the array rather than the last,
e.g. =atan({1,2,3}) entered into a cell will return atan(1), not atan(3).
The problem here is that flattenSingleValue, which says in its comments that
it is supposed to be returning the first item, uses array_pop rather than array_shift.
I have changed that as well. The same mistake was also present in
Cell.php function getCalculatedValue. The correct behavior can be verified
by entering =minverse({-2.5,1.5;2,-1}) into an Excel cell'
Excel flattens the result ({2,3;4,5}) to 2, and so should PhpSpreadsheet.

## [1.8.0] - 2019-07-01
### Security Fix (CVE-2019-12331)
- Detect double-encoded xml in the Security scanner, and reject as suspicious.
- This change also broadens the scope of the `libxml_disable_entity_loader` setting when reading XML-based formats, so that it is enabled while the xml is being parsed and not simply while it is loaded.
On some versions of PHP, this can cause problems because it is not thread-safe, and can affect other PHP scripts running on the same server. This flag is set to true when instantiating a loader, and back to its original setting when the Reader is no longer in scope, or manually unset.
- Provide a check to identify whether libxml_disable_entity_loader is thread-safe or not.
`XmlScanner::threadSafeLibxmlDisableEntityLoaderAvailability()`
- Provide an option to disable the libxml_disable_entity_loader call through settings. This is not recommended as it reduces the security of the XML-based readers, and should only be used if you understand the consequences and have no other choice.
