For one of the Phpstan upgrades, some message text had changed so drastically that the only practical solution at the time was to move the messages from phpstan-baseline.neon to phpstan.neon.dist. This was not ideal, but it allowed us time to move on and study the errors, which I have now done. At one point, Parser is expecting a variable to be an array, and that was not clear from the code. If not an array, the code will error out (which was Phpstan's concern); I have changed it to throw an exception instead. This satisfies Phpstan, and I can get the message out of neon.dist (without needing to restore it to baseline). Unsurprisingly, the exception was never thrown in the existing test suite, although I added a couple of tests to exercise that code.
In Helper/Dimension, Phpstan flagged a statement inappropriately. I suppressed the message using an annotation and filed a bug report https://github.com/phpstan/phpstan/issues/7563. A fix for the problem was merged yesterday, which is good, but it puts us in a tenuous position. The annotation is needed now, but, when the fix is inevitably pushed to the version we use, the no-longer-needed annotation will trigger a different message. Recode so that neither the current nor the future versions will issue a message, eliminating the annotation in the process.
* Document Properties - Coverage and 32-bit-safe Timestamps
While researching an issue, I noticed that coverage of Document/Properties was poor. Further, the use of int timestamps will eventually lead to problems for 32-bit PHP (see issue #1826).
Coverage Changes:
- Many property types with no special handling are enumerated but not tested. These are removed, but will continue to function as before.
- Existing code theoretically allows property to be set to an object, but there is no means to read or write such a property, and, even if there were, I don't believe Excel supports it. Setting a property to an object will now be changed to a no-op (can throw an exception if preferred).
- Since the Properties object now has no members which are themselves objects, there is no need for a deep clone. The untested __clone method is removed.
- Large switch statements are replaced with associative arrays. Scrutinizer will like that.
- Coverage is now 100%.
<!-- end of coverage changes list -->
Timestamp Changes:
- Timestamps will be stored as int if possible, or float if not. This is, or will soon be, needed for 32-bit systems. Tests have been added for beyond-epoch dates, and run successfully with 32-bit.
- LibreOffice doesn't quite get the Created/Modified properties correct. These are written to the file as a string which includes offset from UTC, but LibreOffice ignores the offset portion when displaying them. Code had been generating these in UTC, but now generates them in default timezone, which should meet user's expectations.
<!-- end of timestamp changes list -->
Other Changes:
- Custom properties added to ODS Writer.
- Samples had not been generating any ODS files. One is now generated.
- Ods uses a single 'keywords' property rather than multiple 'keyword' properties.
- Breaking change - default company is changed to null string from Microsoft Corporation.
- Breaking change of sorts - PropertiesTest incorrectly tested a custom date property against a string, Reader/XlsxTest correctly tested against a timestamp converted to a string. PropertiesTest was defective, and will no longer work as coded; anyone using it as a model will likewise have a problem.
- PHP8.1 has been complaining for weeks about a time zone conversion test. I have now downloaded a version, and changed the code so that it will work in 8.1 as well as prior releases. (It is still likely that the existing code should work in 8.1, but I haven't yet figured out how to file a bug report.) In the course of testing, 3 additional 8.1 problems were reported (all along the lines of "can't pass null to strpos"), and are fixed with null coercion.
- Two Calculation tests failed because of large results on 32-bit system. These are corrected by allowing the functions involved to return float|int rather than int. I suspect that there are other functions with this problem, and will investigate as a follow-up activity.
- See issue #2090. I believe that changes between 17.1 and master will merely cause the problematic spreadsheet to fail in a different way. I believe that enclosing in quotes some variables passed to Document/Properties by Reader/Xlsx will eliminate the problem, but, in the absence of an example file, cannot say for sure.
- Properties tests are now separated out from Reader/XlsxTest and Reader/OdsTest, and now test both Read and Write (via reload).
<!-- end of other changes list -->
Miscellaneous Notes:
- There remains no support for Custom Properties in Xls Reader or Writer.
- We now have default timezones for all of PHP itself, Shared/Date, and Shared/Timezone. That is least one too many. I was unable to disentangle the latter two for this change, but will look into deprecating one or the other in future.
* Phpstan
6 baseline deletions, 2 docblock changes
* Scrutinizer's Turn
3 minor errors that hadn't blocked the request.
19_NamedRange.php was not changed to use absolute addressing when that was introduced to Named Ranges. Consequently, the output from this sample has been wrong ever since, for both Xls and Xlsx.
There was an additional problem with Xls. It appears that the Xls Writer Parser does not parse multiple concatenations using the ampersand operator correctly. So, `=B1+" "+B2` was parsed as `=B1+" "`. I believe that this is due to ampersand being treated as a condition rather than an operator; `A1>A2>A3` isn't valid, but `A1&A2&A3` is. My original PR (#1992, which I will now close) only partially resolved this, but I think moving ampersand handling from `condition` to `expression` is fully successful.
There are already more than ample tests for Named Ranges, so I did not add a new one for that purpose. However, I did add a new test for the Xls parser problem.

* Xls Writer - Correct Timestamp Bug, Improve Coverage
I believe that Xls Writer is 100% covered now.
The Xls Writer sets its timestamp incorrectly. The problem is actually
in Shared/Ole::localDateToOLE, which converts its timestamp using
gmmktime; mktime is correct. If I save a file at 3:00 p.m. in San Francisco,
this bug means the time is actually recorded as 3:00 p.m. UTC.
A consequence of this is that if you use Phpspreadsheet to read the
file and save it as a new Xls, the creation timestamp goes further
and further back in time with each generation (or further forward
if east of Greenwich). One of the tests added confirms that
the creation timestamp is consistent with the start and end times
of the test.
The major change in coverage is adding tests to save GIF and BMP
images, which aren't supported in Xls, but are converted to PNG
in the PhpSpreadsheet code.
No code changes. The tests in all of these scripts write to at least
one temporary file, which is then read and not used again. The file
should be deleted to avoid filling up the disk system.
* 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.
Because even if it doesn't make a difference in practice, it is
technically more correct to call static methods statically. It
also better advertise that those methods can be used from any context.
