Question

I’m using the PHPExcel library to open an existing Excel spreadsheet then create a new worksheet in it.

The code I’m using (excluding all of the initialisation/save etc. as that all works correctly) is as follows:

#======================================================#
#  OPEN EXISTING EXCEL SPREADSHEET                     #
#======================================================#

    if (!file_exists( CURRENT_FILE )) {
        exit("Please run " . CURRENT_FILE . " first." . EOL);
    }

    echo date('H:i:s') , " Load from Excel2007 file" , EOL;
    $objPHPExcel = PHPExcel_IOFactory::load( CURRENT_FILE );

#======================================================#



#======================================================#
#  SET UP WORKSHEETS                                   #
#======================================================#

    echo date('H:i:s') , " Create new worksheet for month" , EOL;
    $objPHPExcel->createSheet();
    $objPHPExcel->getActiveSheet()->setTitle( date("d M", strtotime( $weeks[1] ) ) . ' - ' . date("d M", strtotime( $weeks[4] ) ) );

#======================================================#

What I’m trying to do is:

• Open existing Excel file (which may have 1 or more worksheets in already)
• Create a new worksheet
• Set the new worksheet’s title
• Add content to the new worksheet

However, what seems to be happening is this:

• Opens existing Excel file
• Creates a new worksheet
• Set’s the FIRST worksheet’s title to the date I’ve set up
• Adds content to the FIRST worksheet

So, what I think I need to do is this:

• Open existing Excel file
• Add new worksheet
• Get ID of newly-added worksheet (a command like mysql_insert_id())
• Set active worksheet to that ID
• Set title of active worksheet
• Add content to active worksheet

However, I can’t seem to find such a command in the PHPExcel documentation. Does one exist? If not, is there any viable workaround to this? I don’t want to overwrite the existing worksheets in this document.

Thanks in advance,

You could take advantage of the fact that the createSheet() method actually returns your new worksheet.

$newMonthSheet = $objPHPExcel->createSheet();
$newMonthSheet->setTitle( date("d M", strtotime( $weeks[1] ) ) . ' - ' . date("d M", strtotime( $weeks[4] ) ) );
