    //Connect to your database
    $mysqli = new mysqli('localhost', 'root', '', 'mus');

            /*
            * This is the "official" OO way to do it,
            */
            if (mysqli_connect_error()) {
                die('Connect Error (' . mysqli_connect_errno() . ') '
                . mysqli_connect_error());
                }

    //Create new pdf file
    $pdf=new FPDF();

    //Open file
    $pdf->Open();

    //Disable automatic page break
    $pdf->SetAutoPageBreak(false);

    //Add first page
    $pdf->AddPage();

    //set initial y axis position per page
    $y_axis_initial = 25;

    //print column titles for the actual page
    $pdf->SetFillColor(232, 232, 232);
    $pdf->SetFont('Arial', 'B', 10);
    $pdf->SetY($y_axis_initial);
    $pdf->SetX(5);
    $pdf->Cell(10, 6, 'CODE', 1, 0, 'L', 1);
    $pdf->Cell(40, 6, 'NAME', 1, 0, 'L', 1);
    $pdf->Cell(40, 6, 'PRICE', 1, 0, 'L', 1);
    $row_height = 6;
    $y_axis = $y_axis_initial + $row_height;

    //Select the Products you want to show in your PDF file
    $sql = 'SELECT WaiterPckey, WaiterName, WaiterShortName FROM `waitermaster`';
    $result= $mysqli->query($sql); 

    //initialize counter
    $i = 0;

    //Set maximum rows per page
    $max = 25;

    //Set Row Height
    ;

    while($row = $result->fetch_row())
    {
        //If the current row is the last one, create new page and print column title
        if ($i == $max)
        {
            $pdf->AddPage();

            //print column titles for the current page
            $pdf->SetY($y_axis_initial);
            $pdf->SetX(4);
            $pdf->Cell(10, 6, 'CODE', 1, 0, 'L', 1);
            $pdf->Cell(40, 6, 'NAME', 1, 0, 'L', 1);
            $pdf->Cell(40, 6, 'PRICE', 1, 0, 'L', 1);

            //Go to next row
            $y_axis = $y_axis + $row_height;

            //Set $i variable to 0 (first row)
            $i = 0;
        }

        $code = $row[0];
        $price = $row[1];
        $name = $row[2];

        $pdf->SetY($y_axis);
        $pdf->SetX(5);
        $pdf->Cell(10, 6, $code, 1, 0, 'L', 1);
        $pdf->Cell(40, 6, $name, 1, 0, 'L', 1);
        $pdf->Cell(40, 6, $price, 1, 0, 'L', 1);

        //Go to next row
        $y_axis = $y_axis + $row_height;
        $i = $i + 1;
    }


    //Create file
    $pdf->Output();
    ?>
    ?>

回答1:

Use string width for cell with

$string = fullname($USER);
$cellWidth = $pdf->GetStringWidth($string);
$pdf->Cell($cellWidth + 5, 0, $string, 0, 0, 'C', true);

String width doc http://www.fpdf.org/en/doc/getstringwidth.htm

Cell docs http://www.fpdf.org/en/doc/cell.htm

Use table with multicell to solve the issue of dynamic width and height.And click this link to see the example of plugin here.This will be very much useful for dynamic width and height.

For example, you can use this code. You must require mysql_table.php tho.

Define the column first, the size, the name and the align
AddCol (<the name of column in mysql table>, <column size>, <the name you preferred>, <align>)
then you can print the table.
If you think that the first column is smaller, set it to 10 etc.

$pdf->AddCol('code',20,'CODE','C');
$pdf->AddCol('name',40,'NAME');
$pdf->AddCol('price',40,'PRICE','R');
$pdf->Table('-----PUT YOUR SQL QUERY----');
$pdf->Output();
