Fix #4039. Excel sometimes stores the location for a Conditional as, say, `B1:B10 C1:C10` rather than `B1:C10`. PhpSpreadsheet does not have a problem with this, but internally stores it as separate Conditionals, one for each range. (There may be more than 2.) User would like it stored as a single Conditional. Since the range is used as the index of an array which holds the conditionals, there is no technical reason why this can't be done. And it does seem like being able to change multiple ranges all at once has some advantages, whether you're doing it in PhpSpreadsheet or in Excel itself. Making such a change in Xlsx Reader showed no problem in Xlsx Reader and Writer tests. A number of problems did show up in CellMatcherTest, and one in WizardFactoryTest. This was good news, because it meant some of our test spreadsheets used the same type of construction as the test spreadsheet supplied with the issue. So, if additional fixes make the test problems go away, I think no new tests are required. And a smattering of source changes did indeed result in a clean test suite once more. This is a change, but I don't really think it should break anyone. So I don't think it's necessary to add an option to opt in to the old or new behavior. I could be wrong. I'll leave this ticket open for at least a couple of weeks to see if anyone thinks otherwise.
PhpSpreadsheet
PhpSpreadsheet is a library written in pure PHP and offers a set of classes that allow you to read and write various spreadsheet file formats such as Excel and LibreOffice Calc.
Installation
See the install instructions.
Documentation
Read more about it, including install instructions, in the official documentation. Or check out the API documentation.
Please ask your support questions on StackOverflow, or have a quick chat on Gitter.
Patreon
I am now running a Patreon to support the work that I do on PhpSpreadsheet.
Supporters will receive access to articles about working with PhpSpreadsheet, and how to use some of its more advanced features.
Posts already available to Patreon supporters:
- The Dating Game
- A look at how MS Excel (and PhpSpreadsheet) handle date and time values.
- Looping the Loop
- Advice on Iterating through the rows and cells in a worksheet.
And for Patrons at levels actively using PhpSpreadsheet:
- Behind the Mask
- A look at Number Format Masks.
The Next Article (currently Work in Progress):
- Formula for Success
- How to debug formulae that don't produce the expected result.
My aim is to post at least one article each month, taking a detailed look at some feature of MS Excel and how to use that feature in PhpSpreadsheet, or on how to perform different activities in PhpSpreadsheet.
Planned posts for the future include topics like:
- Tables
- Structured References
- AutoFiltering
- Array Formulae
- Conditional Formatting
- Data Validation
- Value Binders
- Images
- Charts
After a period of six months exclusive to Patreon supporters, articles will be incorporated into the public documentation for the library.
PHPExcel vs PhpSpreadsheet ?
PhpSpreadsheet is the next version of PHPExcel. It breaks compatibility to dramatically improve the code base quality (namespaces, PSR compliance, use of latest PHP language features, etc.).
Because all efforts have shifted to PhpSpreadsheet, PHPExcel will no longer be maintained. All contributions for PHPExcel, patches and new features, should target PhpSpreadsheet master branch.
Do you need to migrate? There is an automated tool for that.
