Fix#1275, which had been closed as stale, and is now reopened pending the implementation of this PR. If there is a page break inside a defined print area, Excel may not render the print correctly unless the xml `brk` tag contains a `max` attribute. Libre Office renders it correctly. This seems like a bug in Excel (https://learn.microsoft.com/en-us/openspecs/office_standards/ms-oe376/b32ae11b-dee7-4dcb-9b46-a0feb32ce94f states that Office ignores min and max). PR #3345 (issue #3143) already addressed this problem by allowing the user to explicitly specify a `max` property in the PageBreak object. This PR eliminates the need for the user to make use of that kludge, by adding `max` to the xml whenever a page break is specified on a sheet with a defined print area. Xlsx Reader will now ignore the `max` attribute for row breaks, since it is no longer needed; it already ignores it for column breaks. The user may still set the `max` property if desired, just in case the new treatment is not adequate (I have not found a case where that is true). Two existing unit tests are very marginally changed because of this PR.
Phpstan level 10 reports an enormous number of errors. So does the excluded missingType.iterableValue. I do not plan to introduce either any time soon. But I will submit piecemeal changes from time to time. Changes will be mostly limited to phpdoc type declarations.
Issue #4435 was initially described incorrectly. While investigating the original description, I came upon this problem. Ods Reader is trying to set some cells to null without supplying a valid DataType to setValueExplicit, causing that method to throw an exception. Reader is changed to no longer call that method when value is null and DataType is null-string.
Fix#4416. A peculiar problem indeed. PhpSpreadsheet has been considering a column to be filtered if any cell in the column is filtered and does not preserve the column width if that is the case. It should consider the column not filtered if any cell in the column is not filtered, and consider it filtered only if there are no cells to which that applies. At least, that's how I think it should work, and this change doesn't break any existing tests, and solves this issue.
Fix#4415. We store the rarely-used property Drawing/Shadow/Alpha as an integer representing the percentage. Excel also stores it as an integer, but multiplies it by 1,000, so we divide by 1,000 when we read this value. This can, and in the case of the issue at hand does, leave a fractional portion. Php has deprecated passing a float with a fractional portion to an int argument, so the reporter saw a deprecation message. This is easily fixed.
See discussion #4202. Users can extend Spreadsheet, but the readers cannot return the extended class. This is solved pretty easily by adding a protected method in BaseReader which returns a new Spreadsheet. Users can then extend the Reader which they want, overriding that method to return the extended class.
When I implemented IgnoredErrors (PR #3508), I dealt only with those that I understood well enough to come up with an example. I finally found an example for FormulaRange in the wild, so this PR adds it. Still unsupported are `calculatedColumn`, `emptyCellReferece`, `listDataValidation`, and `unlockedFormula`.
Fix#4362. A similar problem to 4360, Style not handling sheet name with embedded apostrophe properly. And, with two examples in hand, I was able to determine a pattern to find and fix other possible exposures.
Its defaults are to unescape within single quotes, and escape within double quotes and here-docs. Right now, it leaves everything as-is, which means our code is inconsistent and need not be. Further, although dealing with complex regular expressions will never be easy, I find it much easier to figure out what's going on when superfluous back-slashes are removed.
These changes were all made automatically using the "fix" script, so should be reliable. They, of course, pass all unit tests.
Fix#4092. Change default value for Csv Reader autodetect line endings. Prior behavior can be enabled via `setTestAutodetect(true)`.
Change default value for Html Writer "better boolean" logic. Prior behavior can be explicitly enabled via `setBetterBoolean(false)`.
Change default for Xlsx Writer forceFullCalc option. Prior behavior can be explicitly enabled via `setForceFullCalc(null)`.
When the Dynamic Array PR #3962 was introduced, it left the default as Return Array as Value. At some point, the default should be changed to Return Array as Array. This would, of course, be a breaking change, one which will not be part of Release 4. However, it will possibly be part of Release 5.
Rather than relying on the default setting, this PR explicitly sets Return Array as Value when tests require that setting. This will make it easier to identify potential breaks when the default is changed. The entire test suite will now succeed with either setting as default.
In making these changes, a few minor problems were discovered with how Array as Array is handled. These are fixed with this PR.
Fix#4318. Also make getConditionalStyles more useful, by adding a non-default parameter so that all rules pertaining to a single-cell coordinate can be returned, and in priority order. By default, just the first matching rule will be returned.
