Sorry MarkBaker but the link :
do not exist anymore.
I find out why the server cash but I sill lose the drawings and have some new sheets.
The main idee is :
I have a external excel file coming from excel 2007.
I like to modify it with php and save it again in excel format.
I have tried with simple excel document and it works. But with a excel file with drawings within, I have the problems I told you.
This is the code I use (its the example code) :
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$excelFileName = '100101.xlsx';
$objPHPExcel = $objReader->load($excelFileName);
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel,'Excel2007');
Sorry to waste your time
