问题描述
使用以下代码,我可以使用PHPExcel从Excel文件中读取单元格.
With the following code, I am able to read the cells out of an Excel file with PHPExcel.
我目前手动定义要读取的行数和列数.
I currently manually define how many rows and columns to read.
PHPExcel是否可以告诉我必须读取多少行和列才能从工作表中获取所有数据,例如即使某些行和列留为空白?
$file_name = htmlentities($_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>';
解决方案:
谢谢,马克,这是这些功能的完整解决方案:
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>';
推荐答案
$objPHPExcel->setActiveSheetIndex(0)->getHighestColumn();
和
$objPHPExcel->setActiveSheetIndex(0)->getHighestRow();
或
$objPHPExcel->setActiveSheetIndex(0)->calculateWorksheetDimension();
以字符串形式返回范围,例如A1:AC2048
which returns a range as a string like A1:AC2048
尽管其中包含尾随的空白行和列.
although trailing blank rows and columns are included in these.
编辑
或您可以使用迭代器遍历现有行和列,以获取工作表使用范围内的每个单元格.有关示例,请参见生产发行版中的/Tests/28iterator.php.可以将迭代器设置为忽略空格.
or you can use the iterators to loop through the existing rows and columns to get each cell within the worksheets used range. See /Tests/28iterator.php in the production distribution for an example. The iterators can be set to ignore blanks.
