}

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

// set default font subsetting mode
$pdf->setFontSubsetting(true);

// Set font

// print standard ASCII chars, you can use core fonts like
// helvetica or times to reduce file size.
//$pdf->SetFont('dejavusans', '', 14, '', true);
//droidsansfallback简体中文的意思,默认是没有的,需要自己后面加文件
$pdf->SetFont('droidsansfallback', '', 14, '', true);

// Add a page
// This method has several options, check the source code documentation for more information.
$pdf->AddPage();

// set text shadow effect
$pdf->setTextShadow(array('enabled'=>true, 'depth_w'=>0.2, 'depth_h'=>0.2, 'color'=>array(196,196,196), 'opacity'=>1, 'blend_mode'=>'Normal'));

// Set some content to print
$html = <<<EOD

<i>This is the first example of TCPDF library.</i>
<p>This text is printed using the <i>writeHTMLCell()</i> method but you can also use: <i>Multicell(), writeHTML(), Write(), Cell() and Text()</i>.</p>

$pdf->Output('example_001.pdf', 'I');
//不加这个页面输出会是乱码 
ob_end_flush();

此时一个简单的demo 就算是完成了

但是尴尬的是默认并不支持中文,中文会乱码

所以我们要通过额外的配置来进行配置支持

1、下载字体包

提取码: ge26

解压下载好的字体包,并将下面列出的三个文件复制到tcpdf 文件中的 fonts 目录中。

2、修改配置

打开 tcpdf/config/tcpdf_config.php 文件并进行下面的修改操作;

define ('PDF_FONT_NAME_MAIN', 'helvetica');

修改为

define ('PDF_FONT_NAME_MAIN', 'stsongstdlight');
define ('PDF_FONT_NAME_DATA', 'helvetica');

修改为

define ('PDF_FONT_NAME_DATA', 'stsongstdlight');

特别要注意文件必须是UTF-8的。
