How to&Answers:

  print_r( $xlsx->rows() );
} else {
  echo SimpleXLSX::parse_error();
}
?>

SimpleXLSX

Answer:

PHPExcel (see GitHub repository) is probably your best option. It’s very slick and easy to use, I’ve had no problem with the new XLSX format.

Update :

PHPExcel – DEAD

PHPExcel last version, 1.8.1, was released in 2015. The project was officially deprecated in 2017 and permanently archived in 2019.

The project has not be maintained for years and must not be used anymore. All users must migrate to its direct successor PhpSpreadsheet, or another alternative.

Answer:

XLSXReader (available on GitHub) is based on SimpleXLSX (see answer by Sergey Shuchkin).

Convert dates from xlsx using XLSXReader::toUnixTimeStamp.

sample.xlsx

sample.xlsx

sample.php

require (__DIR__ . '/../xlsxreader/XLSXReader.php');

// entire workbook
$xlsx = new XLSXReader('sample.xlsx');
$sheetNames = $xlsx->getSheetNames();

// loop through worksheets
foreach ($sheetNames as $sheetName) {
    $sheet = $xlsx->getSheet($sheetName);

    // worksheet header
    echo('<h3>' . htmlentities($sheetName) . '</h3><table>' . PHP_EOL);
    $xlsx_data = $sheet->getData();
    $header_row_xlsx = array_shift($xlsx_data);

    // header row
    echo('<tr>' . PHP_EOL);
    echo("\t<th>row</th>" . PHP_EOL);
    for ($i = 0; $i < count($header_row_xlsx); $i++) {
        $xlsx_field_name = '' . $header_row_xlsx[$i];
        echo("\t<th>" . htmlentities("$xlsx_field_name") . '</th>' . PHP_EOL);
    }
    echo('</tr>' . PHP_EOL);

    // loop through data rows
    $row_number = 1;
    foreach ($xlsx_data as $row_xlsx) {

        // data row
        echo('<tr>' . PHP_EOL);
        echo("\t<td>" . htmlentities("$row_number") . '</td>' . PHP_EOL);
        for ($i = 0; $i < count($row_xlsx); $i++) {
            $xlsx_field_name = '' . ($i < count($header_row_xlsx) ? $header_row_xlsx[$i] : '');
            if ("$xlsx_field_name" === "DoB") {

                // date value
                $xlsx_field_value = DateTimeImmutable::
                        createFromFormat('U', XLSXReader::toUnixTimeStamp($row_xlsx[$i]))
                        ->format('Y-m-d');
            } else {

                // non-date value
                $xlsx_field_value = $row_xlsx[$i];

            }
            echo("\t<td>" . htmlentities("$xlsx_field_value") . '</td>' . PHP_EOL);
        }
        echo('</tr>' . PHP_EOL);

        $row_number++;
    }
    echo("</table><!-- end of $sheetName -->" . PHP_EOL);
}

output

<h3>Sheet1</h3><table>
<tr>
    <th>row</th>
    <th>Name</th>
    <th>Number</th>
    <th>DoB</th>
</tr>
<tr>
    <td>1</td>
    <td>David</td>
    <td>7</td>
    <td>1988-11-12</td>
</tr>
<tr>
    <td>2</td>
    <td>Walt</td>
    <td>8</td>
    <td>1972-01-19</td>
</tr>
</table><!-- end of Sheet1 -->

While I recommend getting the latest code from GitHub, the entire 1-file library is less than 400 lines of code, so I included the current version (11/10/2018) above.
