1.composer安装
? ? ? ? 1.composer.json添加
"require": {
"setasign/fpdf": "^1.8",
"setasign/fpdi": "^2.0"
}? ? ? ? 2.执行命令?composer require?setasign/fpdi，扩展安装成功后创建vendor/setasign，但此时不支持中文，需要安装支持中文的字体库--simhei
?
2.安装字体黑体simhei
? ? ? ? 将文章最后压缩包解压后，将目录font下4个文件复制到vendor/setasign/fpdf/font下。chinese.php是源文件，适配到自己项目中。PdfChinese.php是我适配自己项目的文件。注意：
在设置字体时，使用 AddGBFont 或AddBig5Font ，chinese.php 334行会报错，$font[‘cw’]为null,原因是使用超全局变量获取GB_widths或Big5_widths失败，可以将这两个变量定义到类里，然后使用this获取。
function AddGBFont($family='GB', $name='STSongStd-Light-Acro')
{
// Add GB font with proportional Latin
$cw = $this->getGBWidths();
$CMap = 'GBKp-EUC-H';
$registry = array('ordering'=>'GB1', 'supplement'=>2);
$this->AddCIDFonts($family,$name,$cw,$CMap,$registry);
}
/**
* 获取GBWidths
*
* @return int[]
*/
public function getGBWidths()
{
return array(

3.项目实战
????????尝试具体FPDF的操作方法，仅供参考。注意可能涉及字符集转换，UTF-8转GB2312。
#1.调用
$add_water_info = [
'iphone' => mb_convert_encoding($phone, "GB2312", 'UTF-8'),
'ip' => mb_convert_encoding($ip, "GB2312", 'UTF-8'),
'c_time' => mb_convert_encoding($c_time, "GB2312", 'UTF-8'),
];
$file_type = 'subscription';
$url = $this->addWater($add_water_info, $file_type);
$data = ['url' => $url];
#2 实现方法
/**
* PDF文件加水印-
*/
private function addWater($add_info, $file_type)
{
$pdf = new PdfChinese();
//设置字体要在实例化之后就设置 否则会报错
$pdf->AddGBFont('simhei', '黑体');
$file = \Yii::$app->basePath . '/static/file/' . $file_type . '.pdf';
//获取页数
$pageCount = $pdf->setSourceFile($file);
//遍历所有页面
for ($pageNo = 1; $pageNo <= $pageCount; $pageNo++) {
//导入页面
$templateId = $pdf->importPage($pageNo);
//获取导入页面的大小
$size = $pdf->getTemplateSize($templateId);
//创建页面（横向或纵向取决于导入的页面大小）
if ($size['width'] > $size['height']) {
$pdf->AddPage('L', array($size['width'], $size['height']));
} else {
$pdf->AddPage('P', array($size['width'], $size['height']));
}
//使用导入的页面
$pdf->useTemplate($templateId);
$pdf->SetFont('simhei', 'B', 9);
if ($pageNo == 2) { //资料只第2页
//手机号
$pdf->SetXY(43, 262.5); //设置位置
$pdf->Cell(0, 7, $add_info['iphone'], 3, 1);
//ip地址
$pdf->SetXY(99, 262.5);
$pdf->Cell(0, 7, $add_info['ip'], 3, 1);
//订阅时间
$pdf->SetXY(157, 262.5);
$pdf->Cell(0, 7, $add_info['c_time'], 3, 1);
}
}
// save file
$outfile = '/tmp/' . uniqid('wk') . '.pdf';
$pdf->Output('F', $outfile, false);
ob_clean();
return $outfile;
}效果如下，
