MATCH with a static array should return the position of the found value based on the values submitted. 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. Fixes #1271 Closes #1332
