如何以 pdf 扩展名创建文件并将内容写入 php 中的该文件？

Question

我已经编写了一个用于生成 pdf 文件并将一些内容写入该特定 pdf 的 php 代码。代码如下所示：

 <?php

    session_start();


    include('../database.php');

    $id = $_GET['id'];

    $_SESSION["cusid"] = $id;


    $invname =  'invoice_'.(mt_rand(1,10000)).'i'.(mt_rand(1,10000));

    $phpFile = fopen('invoice/'.$invname.'.php', "w") or die("Could not open file.");

    $inv = $invname.'.pdf';


    $sql=mysqli_query($con,"update customer set file='$inv' where cusid='$id'");

    $phpContent = '<?php 

                      session_start(); 
                      include("../database.php"); 


                      $id = $inv;

                      echo $id;
     '; 

     fwrite($phpFile, $phpContent);
     fclose($phpFile);
?>

但是使用此代码，会创建 pdf 文件，但是当打开特定的 pdf 时，它会显示无法打开文件的消息。

如何解决这个错误？谁能建议如何解决这个错误？

Answer 1

FPDF 是一个 PHP 类，可让您在不使用 PDFlib 库的情况下生成 PDF 文件。 你可以在这里下载 http://www.fpdf.org/en/download.php 然后提取它并上传到您的服务器。例如到目录public_html/fpdf/

<?php

require('./fpdf.php');

$pdf=new FPDF();

$pdf->AddPage();

$pdf->SetFont('<any_font>','B',16);

$pdf->Cell(40,10,'Your string..'');

$pdf->Output();

?>

以上代码足以创建一个 pdf 文件。将此输入到一个 php 文件中并将其保存在同一目录中。在执行时，您将生成一个 pdf。

你应该试试FPDF。它将帮助您使用 php 制作 pdf 文件。

这里是一些使用 php 的示例 pdf 设计

<?php
require('fpdf.php');//download fpdf library and include here
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(0,10,"Welcome ",3,0,'L');
$pdf->SetFont('Arial', '', 15);
$pdf->SetXY(160 , 30);
$pdf->Write(10, "May 8, 2016");
$pdf->Line(18, 45, 210-20, 45);
$pdf->SetFont('Arial', 'B', 10);
$pdf->SetXY(10 , 54);
$pdf->Write(10, "PAY");
$pdf->SetFont('Arial', '', 11);
$pdf->SetXY(18.5 , 54);
$pdf->Write(10, "ONE THOUSAND TWO HUNDRED THIRTY");

它只是一个示例。你可以自己设计。希望对你有帮助
