    $row = 2;
    foreach ($values['results'] as $value)
    {
        $objPHPExcel->getActiveSheet()->setCellValue('A'.$row,$columnFilter, date("d-m-Y", strtotime($value->payment_date)));
        $objPHPExcel->getActiveSheet()->setCellValue('B'.$row, $value->invoice_number);

This is known bug https://github.com/PHPOffice/PHPExcel/issues/1212 To avoid it you can

  1. downgrade php
  2. upgrade to phpspreadsheet
  3. use Excel2007 writer instead of Excel5
  4. try to suppress warning with error_reporting(E_ALL ^ E_WARNING );

Like voter said, it's a known bug on the Github and won't be fixed because the developers are focussing on a new library. However, instead of down- and upgrading your environment, you could edit a single line and keep your existing implementation.

As seen in the Github thread:

  1. Go to PHPExcel/Writer/Excel5.php
  2. Around line 372, find $endCoordinates = PHPExcel_Cell::stringFromColumnIndex(PHPExcel_Cell::stringFromColumnIndex($iInc - 1));
  3. Change it to only call the function once: $endCoordinates = PHPExcel_Cell::stringFromColumnIndex($iInc - 1);
