PHP + html网页到pdf

Question

我坚持这件事并且不知道该怎么做。我已经搜索了很多次，并且了解了fpdf，html2pdf，tcpdf。

我正在创建一个发票，其中我使用了html和php代码。我想以pdf显示想要将整个页面转换为pdf并打印并保存它的数据。但我不知道该怎么做我是新手，对此并不了解。

尝试了一些代码，但我只是获取html文本作为输出也想要php数据。

这是发票的网页。

代码： 的index.php

<?php
if(!isset($_POST['submit']))
{
?>

你可以使用tcpdf从html渲染pdf。它提供了更大的灵活性 https://tcpdf.org/examples/

看到这段代码，这将生成虚拟发票。

   <?php 

function generateInvoice(){
$invoice_no = 0001;

require_once('tcpdf/tcpdf.php');
class MYPDF extends TCPDF 
{
    public function Header() {
    }


    // Page footer
    public function Footer() {
        // Position at 15 mm from bottom
        $this->SetY(-15);
        // Set font
        $this->SetFont('helvetica', 'I', 12);
    }

}

// create new PDF document
$pdf = new MYPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
// set header and footer fonts
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));

// set default monospaced font
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);

// set margins
$pdf->SetMargins(0, 0, 0);
$pdf->SetHeaderMargin(0);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);

// set auto page breaks
$pdf->SetAutoPageBreak(True, 0);

// set image scale factor
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);

// set some language-dependent strings (optional)
if (@file_exists(dirname(__FILE__).'/lang/eng.php')) {
    require_once(dirname(__FILE__).'/lang/eng.php');
    $pdf->setLanguageArray($l);
}

// ---------------------------------------------------------

//set custom font
//$fontname = TCPDF_FONTS::addTTFfont('OpenSans-Semibold.ttf', 'TrueTypeUnicode', '',12);
// use the font
$pdf->SetFont($fontname, '', 12, '', false);

// add a page
$pdf->AddPage();

$pdf->setFontSize(40);

$pdf->Write(0, 'Company', '', 0, 'C', true, 0, false, false, 0);


$pdf->setFontSize(12);
