phpspreadsheet

I have xlsx tables and I use PhpSpreadsheet to parse them. Some cells format is date. The problem is that PhpSpreadsheet returns the values from date-formatted cells in an unspecified format: // How it looks in excel: 2017.04.08 0:00 $value = $worksheet->getCell('A1')->getValue(); // 42833 - doesn't look like a UNIX time How to get the date from a cell in form of a UNIX time or a DateTimeInterface instance?

But if I'm using my web application to generate an excel report file (PHP, using CodeIgniter and Laravel). It displays an error " 'Wrong number of arguments for INDEX() function: 5 given, between 1 and 4 expected' " Here's my sample code snippet: $code = "=INDEX(\$E\$4:\$E\$$occurance, AGGREGATE(15,6,ROW(\$1:\$$occurance) / (\$J\$4:\$J\$$occurance=M$top_cell), COUNTIF(\$M\$4:M

I am developing a web application made using PHP (withh CodeIgniter as the framework) that should produce an excel file report as as summary of data.
