header("Content-Type: text/html");

echo "----------<br>";

// Create an instance of the class that exports Excel files
$workbook = new COM("EasyXLS.ExcelDocument");

// Create two worksheets
$workbook->easy_addWorksheet_2("First tab");
$workbook->easy_addWorksheet_2("Second tab");

// Set the password for protecting the Excel file when the file is open
$workbook->easy_getOptions()->setPasswordToOpen("password");

// Export Excel file
echo "Writing file: C:\Samples\Tutorial27 - protect Excel with password and encryption.xlsx<br>";
$workbook->easy_WriteXLSXFile("C:\Samples\Tutorial27 - protect Excel with password and encryption.xlsx");

// Confirm export of Excel file
if ($workbook->easy_getError() == "")
    echo "File successfully created.";

    echo "Error encountered: " . $workbook->easy_getError();

// Dispose memory
$workbook->Dispose();
$workbook = null;

?>
