include("Alignment.inc");
include("Border.inc");
include("Color.inc");

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

$workbook = new COM("EasyXLS.ExcelDocument");
	
// Create two worksheets
$workbook->easy_addWorksheet_2("First tab");
$workbook->easy_addWorksheet_2("Second tab");

// Protect the first sheet
$workbook->easy_getSheetAt(0)->setSheetProtected(true);

// Get the table of data for the first worksheet
$xlsFirstTable = $workbook->easy_getSheetAt(0)->easy_getExcelTable();

// Create the formatting style for the header
$xlsStyleHeader = new COM("EasyXLS.ExcelStyle");
$xlsStyleHeader->setFont("Verdana");
$xlsStyleHeader->setFontSize(8);
$xlsStyleHeader->setItalic(True);
$xlsStyleHeader->setBold(True);
$xlsStyleHeader->setForeground((int)$COLOR_YELLOW);
$xlsStyleHeader->setBackground((int)$COLOR_BLACK);
$xlsStyleHeader->setBorderColors ((int)$COLOR_GRAY, (int)$COLOR_GRAY, (int)$COLOR_GRAY, (int)$COLOR_GRAY);

// Add data in cells for report header
for ($column=0; $column<5; $column++)
{
    $xlsFirstTable->easy_getCell(0,$column)->setValue("Column " . ($column + 1));
    $xlsFirstTable->easy_getCell(0,$column)->setStyle($xlsStyleHeader);

    // Add comment for report header cells
    $xlsFirstTable->easy_getCell(0, $column)->setComment_2("This is column no " . ($column + 1));
}
$xlsFirstTable->easy_getRowAt(0)->setHeight(30);

// Create a formatting style for cells
$xlsStyleData = new COM("EasyXLS.ExcelStyle");
$xlsStyleData->setHorizontalAlignment($ALIGNMENT_ALIGNMENT_LEFT);
$xlsStyleData->setForeground((int)$COLOR_DARKGRAY);
$xlsStyleData->setWrap(false);
// Protect cells
$xlsStyleData->setLocked(true);

for ($row=0; $row<100; $row++)
{
    for ($column=0; $column<5; $column++)
    {
        $xlsFirstTable->easy_getCell($row+1,$column)->setValue("Data " . ($row + 1) .
                                                               ", " . ($column + 1));
        $xlsFirstTable->easy_getCell($row+1,$column)->setStyle($xlsStyleData);
    }
}

// Set column widths
$xlsFirstTable->setColumnWidth_2(0, 70);
$xlsFirstTable->setColumnWidth_2(1, 100);
$xlsFirstTable->setColumnWidth_2(2, 70);
$xlsFirstTable->setColumnWidth_2(3, 100);
$xlsFirstTable->setColumnWidth_2(4, 70);
	
// Export Excel file
echo "Writing file: C:\Samples\Tutorial07 - cell comment in Excel.xlsx<br>";
$workbook->easy_WriteXLSXFile("C:\Samples\Tutorial07 - cell comment in Excel.xlsx");

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

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

?>

Overloaded methods
For methods with same name but different parameters, only the first method overload retains the original name. Subsequent overloads are uniquely renamed by appending to the method name '_2', '_3', etc (method, method_2, method_3), an integer that corresponds to the order of declaration that can be found in EasyXLS.h, a file that comes with EasyXLS installation.
