php+tcpdf生成pdf文件

首先composer下载tcpdf插件


composer require tecnickcom/tcpdf


重要！！！
一定是这样
use TCPDF;


然后将TCPDF文件中的第8874行的gzuncompress函数,换成zlib_decode即可



控制器方法
pulic function ceshi()
{
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('Nicola Asuni');
$pdf->SetTitle('TCPDF Example 001');
$pdf->SetSubject('TCPDF Tutorial');
$pdf->SetKeywords('TCPDF, PDF, example, test, guide');
$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));
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
$pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
$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->SetFont('stsongstdlight', '', 12);
$pdf->AddPage();
$pdf->setTextShadow(array('enabled'=>true, 'depth_w'=>0.2, 'depth_h'=>0.2, 'color'=>array(196,196,196), 'opacity'=>1, 'blend_mode'=>'Normal'));
$html = “”//此处是HTML代码，用EDO来包住
$pdf->writeHTMLCell(0, 0, '', '', $html, 0, 1, 0, true, '', true);
$pdf->Output('example_001.pdf', 'I');
}


Output方法的case 'I':（打印PDF）、case 'D':（下载PDF）、case 'FD':（保存到本地文件）


如果要将pdf保存到服务器本地，那么就需要修改一下最后这句，把路径换成绝对路径
$pdf->Output(ROOT_PATH . 'pdf/'. time() .'.pdf', 'F');
