使用以下代码,我可以使用PHPExcel从Excel文件中读取单元格.

我目前手动定义要读取的行数和列数.

有没有一种方法PHPExcel可以告诉我有多少行和列我必须读取以从工作表中获取所有数据,例如,即使某些行和列留空？

$file_name = htmlentities($_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 . '&nbsp;';
        echo '</td>';
    }
    echo '</tr>';
}
echo '</table>';

解:

谢谢,Mark,这是这些功能的完整解决方案:

$file_name = htmlentities($_POST['file_name']);
$sheet_name = htmlentities($_POST['sheet_name']);
$number_of_columns = …
