mpdf is a PHP library for generating PDF files, which supports multiple languages ​​and various output formats. It's easy to use and can be personalized via configuration files. Let's see how to use mpdf with CakePHP.

Step 1: Install mpdf library

Before using mpdf, you need to install it first. This can be done by:

(1) Download the latest version of the mpdf library (https://github.com/mpdf/mpdf)

(2) Copy the mpdf folder to your In the vendor directory of the project.

(3) Add the following lines in your Controller:

use MpdfMpdf;

Step 2: Generate PDF file

Next, let’s see how to generate a PDF file in CakePHP PDF file. We will use a simple example that generates a PDF file containing a piece of text.

public function pdf()
{
    $mpdf = new Mpdf();

    $mpdf->WriteHTML('<p>Hello, world!</p>');

    $mpdf->Output();
}

In the above example, we first instantiate the mpdf class and assign it to the $mpdf variable. We then use the WriteHTML function to add a text block to the PDF file. Finally, we use the Output function to send the generated PDF file to the browser. In this example, a file named output.pdf will be generated in the current directory.

Step 3: Personalization

mpdf library allows various personalization settings, such as adding headers and footers, setting page size and layout, etc. Here are some examples:

public function pdf()
{
    // 个性化设置
    $mpdfConfig = [
        // 设置页面尺寸和方向
        'format' => 'A4',
        'orientation' => 'L',

        // 添加页眉页脚
        'default_font_size' => 8,
        'margin_top' => 30,
        'margin_bottom' => 0,
        'margin_footer' => 0,
        'margin_header' => 0,
        'footer_content' => '<p>Page {PAGENO} of {nb}</p>',

        // 设置字体
        'fontDir' => '/usr/share/fonts/truetype/msttcorefonts/',
        'fontdata' => [
            'arial' => [
                'R' => 'arial.ttf',
                'B' => 'arialbd.ttf',
            ]
        ],
    ];

    $mpdf = new Mpdf($mpdfConfig);

    $mpdf->WriteHTML('<p>Hello, world!</p>');

    $mpdf->Output();
}

In the above example, we set various personalization settings by passing the $mpdfConfig array to the constructor of the Mpdf class. We set the page size and orientation, added a header and footer, and set a custom font.
