The built-in ZipArchive class does not have the ability
to accept streams. This means that we would always have to
write the zip to disk. The ZipStream library does offer
support for writing to streams.
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.

`$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'.

Indentation in the xml leaves spaces in style string even after
replacing newlines. Replacing the spaces ensures no spaces in keys
of the resulting style-array

Fluent methods, especially setters, return the object on which are
called. This is documented in PHPDoc using the `$this` keyword, which
is equivalent to `static` with the additional notion of object identity.
This helps IDEs and static analysis tools provide more meaningful output.
The `setRange` method of the `Xlsx/AutoFilter` class expects a filter
range format like "A1:E10". The returned value from
`$this->worksheetXml->autoFilter['ref']` could contain "$" and returning
a value like "$A$1:$E$10".

When freeze pane is in use on a worksheet, PhpSpreadsheet saves to Xlsx in such
a way that the active cell is always set to the top left cell below the freeze
pane. I find it difficult to understand why:
1. You have given users the setSelectedCells function, but then choose to
ignore it.
2. Excel itself does not act in this manner.
3. PHPExcel did not act in this manner.
4. PhpSpreadsheet when writing to Xls does not act in this manner.
This is especially emphasized because the one test in FreezePaneTest which
would expose the difference is the only test in that member which is
not made for both Xls and Xlsx.
5. It is *really* useful to be able to open a spreadsheet anywhere, even when
it has header rows.
Closes#1323
* Changes to WEEKNUM and YEARFRAC
The optional second parameter for WEEKNUM can take any of 10 values
(1, 2, 11-17, and 21), but currently only 1 and 2 are supported.
This change adds support for the other 8 possibilities.
YEARFRAC in Excel does not require that end date be before start date,
but PhpSpreadsheet was returning an error in that situation.
YEARFRAC third parameter (method) of 1 was not correctly implemented.
I was able to find a description of the algorithm, and documented
that location in the code, and implemented according to that spec.
PHPExcel had a (failing) test to assert the result of
YEARFRAC("1960-12-19", "2008-06-28", 1). This test had been dropped
from PhpSpreadsheet, and is now restored; several new tests have
been added, and verified against Excel.
* Add YEARFRAC Tests
Scrutinizer reported a very mysterious failure with no details.
project.metric_change("scrutinizer.test_coverage", < 0),
without even a link to explain what it is reporting.
It is possible that it was a complaint about code coverage.
If so, I have added some tests which will, I hope, eliminate the problem.
* Make Array Constant
Responding to review from Mark Baker.
* Merge with PR 1362 Bugfix 1161
Travis CI reported problem with Calculation.php (which is not part
of this change).
That was changed in master a few days ago
(delete some unused code).
Perhaps the lack of that change is the problem here.
Merging it manually.
Support for the CONTAINSBLANKS conditional style was added a while ago.
However, that support was on write only; any cells which used
CONTAINSBLANKS on a file being read would drop that style.
I am also adding support for NOTCONTAINSBLANKS, on read and write.
* Handle Error in Formula Processing Better for Xls
When there is an error writing a formula to an Xls file,
which seems to happen when a defined name is part of a formula,
the cell is currently left blank. A better result would be to
write the calculated value of the formula.
* Making Changes Suggested in Review
Per comment from Mark Baker:
1. Made return codes from writeFormula into constants.
2. Skipped redundant call to getCellValue when possible.
3. Added support for bool type, adding additional tests
for bool and string.
Per comment from PowerKiki:
1. Used standardized convention for assigning file name in test.
Since before this change, save would throw Exception, I kept
the unlink for the file in tearDown.
* Initial unit test for locale floats
This will require potential modification of the TravisCI environment to support other locales
* var_dump to check output on TravisCI
* Fix assertions for double/float and with/without line reference
* Style in unit test
* Handle ConditionalStyle NumberFormat When Reading Xlsx File
ReadStyle in Reader/Xlsx/Styles.php expects numberFormat to be a string.
However, when reading conditional style in Xlsx file, NumberFormat
is actually a SimpleXMLElement, so is not handled correctly.
While testing this change, it turned out that reader always expects
that there is a "SharedString" portion of the XML, which is not
true for spreadsheets with no string data, which causes a
run-time message.
Likewise, when conditional number format is not one of the built-in
formats, a run-time message is issued because 'isset' is used
to determine existence rather than 'array_key_exists'.
The new workbook added to the testing data demonstrates both those
problems (prior to the code changes).
* Move Comment to Resolve Conflict
Github reports conflict involving placement of one comment statement.
* Respond to Scrutinizer Style Suggestion
Change detection for empty SimpleXMLElement.
