What are the best practices for integrating Excel sheets with HTML pages in an Intranet environment using PHP?

When integrating Excel sheets with HTML pages in an Intranet environment using PHP, the best practice is to use a library like PHPExcel to read the Excel data and convert it into a format that can be easily displayed on an HTML page. This involves reading the Excel file, extracting the data, and then formatting it into a table or other HTML elements for display.

// Include PHPExcel library
require_once 'PHPExcel/Classes/PHPExcel.php';

// Load Excel file
$excelFile = 'path/to/your/excel/file.xlsx';
$excelReader = PHPExcel_IOFactory::createReaderForFile($excelFile);
$excelObj = $excelReader->load($excelFile);

// Get the first sheet in the Excel file
$sheet = $excelObj->getSheet(0);

// Get the highest row and column in the Excel sheet
$highestRow = $sheet->getHighestRow();
$highestColumn = $sheet->getHighestColumn();

// Loop through each row and column to extract data
$html = '<table>';
for ($row = 1; $row <= $highestRow; $row++) {
    $html .= '<tr>';
    for ($col = 'A'; $col <= $highestColumn; $col++) {
        $cell = $sheet->getCell($col . $row)->getValue();
        $html .= '<td>' . $cell . '</td>';
    }
    $html .= '</tr>';
}
$html .= '</table>';

// Display the HTML table on the page
echo $html;
