With the following code, I am able to read the cells out of an Excel file with PHPExcel.
I currently manually define how many rows and columns to read.
Is there a way that PHPExcel can tell me how many rows and columns I have to read to get all the data out of the worksheet, e.g. even if some rows and columns are left blank?
$file_name = htmlentities($_POST['file_name']);
$sheet_name = htmlentities($_POST['sheet_name']);
$number_of_columns = htmlentities($_POST['number_of_columns']);
$number_of_rows = htmlentities($_POST['number_of_rows']);
$objReader = PHPExcel_IOFactory::createReaderForFile("data/" . $file_name);
$objReader->setLoadSheetsOnly(array($sheet_name));
$objReader->setReadDataOnly(true);
$objPHPExcel = $objReader->load("data/" . $file_name);
echo '<table border="1">';
for ($row = 1; $row < $number_of_rows; $row++) {
echo '<tr>';
for ($column = 0; $column < $number_of_columns; $column++) {
$value = $objPHPExcel->setActiveSheetIndex(0)->getCellByColumnAndRow($column, $row)->getValue();
echo '<td>';
echo $value . ' ';
echo '</td>';
}
echo '</tr>';
}
echo '</table>';
Solution:
Thanks, Mark, here's the full solution with those functions:
$file_name = htmlentities($_POST['file_name']);
$sheet_name = htmlentities($_POST['sheet_name']);
$number_of_columns = htmlentities($_POST['number_of_columns']);
$number_of_rows = htmlentities($_POST['number_of_rows']);
$objReader = PHPExcel_IOFactory::createReaderForFile("data/" . $file_name);
$objReader->setLoadSheetsOnly(array($sheet_name));
$objReader->setReadDataOnly(true);
$objPHPExcel = $objReader->load("data/" . $file_name);
$highestColumm = $objPHPExcel->setActiveSheetIndex(0)->getHighestColumn();
$highestRow = $objPHPExcel->setActiveSheetIndex(0)->getHighestRow();
echo 'getHighestColumn() = [' . $highestColumm . ']<br/>';
echo 'getHighestRow() = [' . $highestRow . ']<br/>';
echo '<table border="1">';
foreach ($objPHPExcel->setActiveSheetIndex(0)->getRowIterator() as $row) {
$cellIterator = $row->getCellIterator();
$cellIterator->setIterateOnlyExistingCells(false);
echo '<tr>';
foreach ($cellIterator as $cell) {
if (!is_null($cell)) {
$value = $cell->getCalculatedValue();
echo '<td>';
echo $value . ' ';
echo '</td>';
}
}
echo '</tr>';
}
echo '</table>';
