I am trying to import 500,000 records in the excel file but its giving me error.
Here is the error :
Warning: XMLWriter::endElement(): Memory allocation failed : growing buffer in \reports\Classes\PHPExcel\Writer\Excel2007\Worksheet.php on line 1156
I have already set PHPMemory = -1 in php.ini.
Please suggest how can i resolve this issue.
Thanks in Advance,
