Looping through worksheets with PHPExcel

Question

I\'m using the PHPExcel library to read an Excel file and perform processing on it. I want to loop through each worksheet. I checked the documentation and all I could find was

Answer 1

Here's a useful function I use for iterating over sheets and returning an array of cell values for each with the sheet title as array key:

function getSheets($fileName) {
    try {
        $fileType = PHPExcel_IOFactory::identify($fileName);
        $objReader = PHPExcel_IOFactory::createReader($fileType);
        $objPHPExcel = $objReader->load($fileName);
        $sheets = [];
        foreach ($objPHPExcel->getAllSheets() as $sheet) {
            $sheets[$sheet->getTitle()] = $sheet->toArray();
        }
        return $sheets;
    } catch (Exception $e) {
         die($e->getMessage());
    }
}
