PHP实现word转pdf的两种方式(有用!)

	composer require phpoffice/phpword
	composer require tecnickcom/tcpdf

//			你的初始文件地址
			$word = 'test.docx';
           \PhpOffice\PhpWord\Settings::setPdfRendererPath(base_path('vendor/tecnickcom/tcpdf'));
           //设置转换pdf的类库名（DomPDF、MPDF、TCPDF）需要下载对应的类库
           \PhpOffice\PhpWord\Settings::setPdfRendererName('TCPDF');
 //				加载word文件
           $wordPdf = \PhpOffice\PhpWord\ioFactory::load($word);
//			读取生成的docx文件 并且指明要生成的文件格式
           $pdfWriter = \PhpOffice\PhpWord\IOFactory::createWriter($wordPdf , 'PDF');
//			设置文字字体，文字大小
           $pdfWriter->SetFont('wryh','',20,'',false);
//			生成pdf文件 的保存地址
           $temp_path = 'test.pdf'
//			文件保存        
           $pdfWriter->save($temp_path);
            return $temp_path;

先为安装 libreoffice 创建一个文件夹，用以保存下载的压缩包 
	mkdir libreoffice
	cd libreoffice/
