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');
Copy after login

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);
Copy after login
