PHP如何生成PDF文档?

使用PHPTCPDF

实际工作中,我们要使用PHP动态的创建PDF文档,目前有许多开源的PHP创建PDF的类库,今天我给大家来介绍一款优秀的PDF库,它就是TCPDF,TCPDF是一个用于快速生成PDF文件的PHP5函数包。TCPDF基于FPDF进行扩展和改进,增强了实用功能。

特性

TCPDF具有以下特性:

1、支持页面页脚;

2、支持HTML标签代码;

3、支持jpg/png/gif/svg图形图像;

4、支持表格;

5、支持中文字符;(有些PDF类不支持中文或者处理中文相当麻烦)

6、自动分页,自动页码,等等。

 

 

如何使用

您可以从TCPDF官网获取最新版本:http://www.tcpdf.org。官网提供了几十个示例以及说明文档,下载解压后一定要注意文件路径,如何使用TCPDF,可以从以下5个步骤完成:

1、require_once导入tcpdf.php文件及相关配置信息;

2、实例化TCPDF;

3、设置PDF文档的格式,包括文档信息、页眉、页尾、字体、外间距、图片边框、分页等;

4、导入PDF文档的内容,可以是单行或多行简单字符串,也可以HTML格式的字符串等;

5、输出PDF文档。

代码示例:

require_once('tcpdf.php'); 
//实例化 
$pdf = new TCPDF('P', 'mm', 'A4', true, 'UTF-8', false); 
  
// 设置文档信息 
$pdf->SetCreator('Helloweba'); 
$pdf->SetAuthor('yueguangguang'); 
$pdf->SetTitle('Welcome to helloweba.com!'); 
$pdf->SetSubject('TCPDF Tutorial'); 
$pdf->SetKeywords('TCPDF, PDF, PHP'); 
  
// 设置页眉和页脚信息 
$pdf->SetHeaderData('logo.png', 30, 'Helloweba.com', '致力于WEB前端技术在中国的应用',  
      array(0,64,255), array(0,64,128)); 
$pdf->setFooterData(array(0,64,0), array(0,64,128)); 
  
// 设置页眉和页脚字体 
$pdf->setHeaderFont(Array('stsongstdlight', '', '10')); 
$pdf->setFooterFont(Array('helvetica', '', '8')); 
  
// 设置默认等宽字体 
$pdf->SetDefaultMonospacedFont('courier'); 
  
// 设置间距 
$pdf->SetMargins(15, 27, 15); 
$pdf->SetHeaderMargin(5); 
$pdf->SetFooterMargin(10); 
  
// 设置分页 
$pdf->SetAutoPageBreak(TRUE, 25); 
  
// set image scale factor 
$pdf->setImageScale(1.25); 
  
// set default font subsetting mode 
$pdf->setFontSubsetting(true); 
  
//设置字体 
$pdf->SetFont('stsongstdlight', '', 14); 
  
$pdf->AddPage(); 
  
$str1 = '欢迎来到Helloweba.com'; 
  
$pdf->Write(0,$str1,'', 0, 'L', true, 0, false, false, 0); 
  
//输出PDF 
$pdf->Output('t.pdf', 'I');

保存后用浏览器打开,如果您的系统安装了PDF阅读器或者使用google chrome直接在浏览器中打开,否则会提示下载生成的PDF。

★ 如果需要直接保存到磁盘的某个目录下:

$res = $pdf->Output('aaa.pdf', 'S');
file_put_contents('ttt.pdf', $res);

How can you check if a PHP session has already started?How can you check if a PHP session has already started?Apr 30, 2025 am 12:20 AM

In PHP, you can use session_status() or session_id() to check whether the session has started. 1) Use the session_status() function. If PHP_SESSION_ACTIVE is returned, the session has been started. 2) Use the session_id() function, if a non-empty string is returned, the session has been started. Both methods can effectively check the session state, and choosing which method to use depends on the PHP version and personal preferences.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching
