* Initia work on differentiating between empty arguments and null arguments passed to Excel functions Previously we always passed a null value for an empty argument (i.e. where there was an argument separator in the function call without an argument.... PHP doesn't support empty arguments, so we needed to provide some value but then it wasn't possible to differentiate between a genuine null argument (either a literal null, or a null cell value) and the null that we were passing to represent an empty argument value. This change evaluates empty arguments within the calculation engine, and instead of passing a null, it reads the signature of the required Excel function, and passes the default value for that argument; so now a null argument really does mean a null value argument. * If the Excel function implementation doesn't accept any arguments; or once we reach a variadic argument, or try to pass more arguments than the method supports in its signature, then there's no point in checking for defaults, and to do so will lead to PHP errors, so break out of the default replacement loop |

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.
