Delete rows with PHPExcel - phpexcel

Question

I want to delete all rows that start with "//", from Excel sheet, with PHPExcel.
My code:
require '../Classes/PHPExcel.php';
require_once '../Classes/PHPExcel/IOFactory.php';
error_reporting(E_ALL & ~E_STRICT & ~E_NOTICE);
$path = "del_head.xls";
$objPHPExcel = PHPExcel_IOFactory::load($path);
$objWorksheet = $objPHPExcel->getActiveSheet();
$highestRow = $objWorksheet->getHighestRow();
$highestColumn = $objWorksheet->getHighestColumn();
$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
for($row=1; $row < $highestRow; ++$row){
$value = $objPHPExcel->getActiveSheet()->getCell('A'.$row)->getValue();
if (substr($value,0,2) == "//") {
$objPHPExcel->getActiveSheet()->removeRow($row, $row);
}
}
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, "Excel2007");
$objWriter->save($path);
But, the code not delete all rows that start with "//".
I think the problem is with function 'removeRow'.
Thank you very much in advance.

Answer 1

Replace this line
$objPHPExcel->getActiveSheet()->removeRow($row, $row);
with
$objPHPExcel->getActiveSheet()->removeRow($row);

Answer 2

There's one obvious problem with your call to removeRow(): The first argument is the starting row, the second is the number of rows to remove; so if you find a // at row 5, then you're telling PHPExcel to remove 5 rows starting from row 5 (i.e. rows 5 to 9).
You're also reading a file with a .xls extension (assuming that it's a BIFF file from the extension), but saving with the same .xls filename as an OfficeOpenXML file (which is normally a .xlsx file).
So what format actually is your file? What does a call to the IOFactory's identify() method recognise it as? If it's actually a comma- or tab-separated value file (most likely to have a leading //), then you'd be better using PHP's fgetcsv() and fputcsv() functions to process it to remove those lines.

Try this code, Its worked me
$filename = 'path/example.xls';
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objPHPExcel = $objReader->load($filename);
$objWorksheet = $objPHPExcel->getActiveSheet();
$row_id = 1; // deleted row id
$number_rows = 2; // number of rows count
if ($objWorksheet != NULL) {
if ($objWorksheet->removeRow($row_id, $number_rows)) {
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save($filename);
}
}

Please, check the value assigned on line:
$highestRow = $objWorksheet->getHighestRow();
I've tested this code and the value is always 1
