tcpdf類生成PDF文件

tcpdf類生成PDF文件：

        一、安裝tcpdf

        二、tcpdf插件中examples

        三、寫入方法生成pdf頁面

                方法一、在index.php中寫入pdfdemo方法

                             01）、使用命名空間

                                        user TCPDF;       

                             02）、引入example01方法                             

 public function pdfdemo(){
        $html = '<h1 style="color: #0000FF">hello tcpdf</h1><br>我是波哥,我愛Thinkphp!!!<img src="logo.png"/>';
        Pdf::createPdf($html);
  exit();
    }
    public function  pdfdemo1(){

// create new PDF document
        $pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);

// set document information
        $pdf->SetCreator(PDF_CREATOR);
        $pdf->SetAuthor('Nicola Asuni');
        $pdf->SetTitle('TCPDF Example 001');
        $pdf->SetSubject('TCPDF Tutorial');
        $pdf->SetKeywords('TCPDF, PDF, example, test, guide');

// set default header data
        $pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, PDF_HEADER_TITLE.' 001', PDF_HEADER_STRING, array(0,64,255), array(0,64,128));
        $pdf->setFooterData(array(0,64,0), array(0,64,128));

// set header and footer fonts
        $pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
        $pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));

// set default monospaced font
        $pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);

// set margins
        $pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
        $pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
        $pdf->SetFooterMargin(PDF_MARGIN_FOOTER);

// set auto page breaks
        $pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);

// set image scale factor
        $pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);

// set some language-dependent strings (optional)
        if (@file_exists(dirname(__FILE__).'/lang/eng.php')) {
            require_once(dirname(__FILE__).'/lang/eng.php');
            $pdf->setLanguageArray($l);
        }

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

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

// Set font
// dejavusans is a UTF-8 Unicode font, if you only need to
// print standard ASCII chars, you can use core fonts like
// helvetica or times to reduce file size.
        $pdf->SetFont('dejavusans', '', 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
<h1>Welcome to <a href="http://www.tcpdf.org" style="text-decoration:none;background-color:#CC0000;color:black;">&nbsp;<span style="color:black;">TC</span><span style="color:white;">PDF</span>&nbsp;</a>!</h1>
<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>

EOD;

// Print text using writeHTMLCell()
        $pdf->writeHTMLCell(0, 0, '', '', $html, 0, 1, 0, true, '', true);

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

// Close and output PDF document
// This method has several options, check the source code documentation for more information.
        $pdf->Output('example_001.pdf', 'I');

        exit();
    }
}

                方法二、封裝一個topdf方法

                              01）、配置擴展文件extend/Pdf/Pdf.php                                   

namespace Pdf;
use TCPDF;
class Pdf
{
    public static function createPdf($html){
        $pdf = new Tcpdf(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
        // 設置打印模式
        $pdf->SetCreator(PDF_CREATOR);
        $pdf->SetAuthor('邵大蝦');//作者
        $pdf->SetTitle('邵大蝦pdf-Title');//標題
        $pdf->SetSubject('邵大蝦pdf-Subject'); //主題
        $pdf->SetKeywords('TCPDF, PDF,邵大蝦');//關鍵詞
        // 是否顯示頁眉
        $pdf->setPrintHeader(true);
        // 設置頁眉顯示的內容
        $pdf->SetHeaderData('logo.jpg', 10, '邵大蝦', 'http://www.were18.cn', array(255,0,0), array(0,0,0));
        // 設置頁眉字體
        $pdf->setHeaderFont(Array('stsongstdlight', '', '12'));
        // 頁眉距離頂部的距離
        $pdf->SetHeaderMargin('0');

        // 是否顯示頁腳
        $pdf->setPrintFooter(true);
        // 設置頁腳顯示的內容
        $pdf->setFooterData(array(0,64,0), array(0,64,128));
        // 設置頁腳的字體
        $pdf->setFooterFont(Array('stsongstdlight', '', '10'));
        // 設置頁腳距離底部的距離
        $pdf->SetFooterMargin('10');
        // 設置默認等寬字體
        $pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
        // 設置行高
        $pdf->setCellHeightRatio(1);
        // 設置左、上、右的間距
        $pdf->SetMargins('10', '10', '10');
        // 設置是否自動分頁  距離底部多少距離時分頁
        $pdf->SetAutoPageBreak(TRUE, '15');
        // 設置圖像比例因子
        $pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
        if (@file_exists(dirname(__FILE__).'/lang/eng.php')) {
            require_once(dirname(__FILE__).'/lang/eng.php');
            $pdf->setLanguageArray($l);
        }
        $pdf->setFontSubsetting(true);
        $pdf->AddPage();
        // 設置字體
        $pdf->SetFont('stsongstdlight', '', 14, '', true);
        $pdf->writeHTMLCell(0, 0, '', '', $html, 0, 1, 0, true, '', true);
        $pdf->Output('view.pdf', 'I');
    }

}

                              02）、在index.php中定義方法                                       

 public function topdf(){
      $html = '<h1 style="color: #0000FF">hello tcpdf</h1><br>我是邵大蝦,我愛Thinkphp!!!<img src="logo.png"/>';
      Pdf::createPdf($html);
exit();
  }

        注意、tcpdf使用注意：
                1.注意引入命名空間
                USE TCPDF
                2.注意設置logo的路徑
                默認地址爲 tcpdf庫裏面的examples/images文件夾內
