I am using Mpdf to make some values that I have saved in SESSIONS in php become a report, so far so good, but the page that I want to turn into report has graphics Js, Highcharts, I don’t know how to export these charts directly to the report that will be in pdf.

Unfortunately mpdf does not support javascript, so for you to show a highchart in your pdf you will have to export it in image format.
An example of this would be:
var hightchart = $('#container').highcharts().getSVG(); // Pega o highcharts e transforma em SVG.
Send the result by ajax to php, and then include it in your mpdf:
$html = "Olha um gráfico: ". $_POST['hightchart '];
include 'lib/mpdf/mpdf.php';
$mpdf = new mPDF();
$mpdf->WriteHTML($html);
$mpdf->Output('exemplo.pdf', 'I');
Example: Transforming graphic into image
Documentation: Highcharts Chart.getSVG
My Chart is separated in the project, as I take his ID and take it to the Php code where the MPDF ? I must save the highchart variable with the values of my chart and it in my Php code, make the request via Ajax ?

To generate PDF tries to use a library called wkhtmltopdf, it is an interesting project that transforms into PDF the page rendered by Webkit, Google rendering engine.
If the charts are empty, try disabling the highchart animations.
On the web ? how to integrate this to Php for example ? rs
You have to install wkhtmltopdf on the server, or check if it is already installed. Then use a PHP library to create the PDF files. Example: https://github.com/mikehaertl/phpwkhtmltopdf OBS: If you are using a PHP framework, check if there are any wkhtmltopdf modules available for it.
