php word转pdf 读取pdf内容

1.word转pdf 需要用到 LibreOffice 便携版  如果是linux可以去官网查看安装命令

　　下载地址：https://zh-cn.libreoffice.org/download/portable-versions/

$retval = 1;
// exec() might be disabled url需要填写相对地址
$cmd = "D:LibreOfficePortable/LibreOfficeWriterPortable.exe  --headless --convert-to pdf D:phpstudy_proWWWReadWordupload\$name.docx --outdir  D:phpstudy_proWWWReadWordupload\";
if (function_exists('exec')){
    @exec($cmd, $output, $retval);
}
// Did it work?
if ($retval > 0){
    exit('process_failed');
}else{
    sleep(5);
    header('location:./phpword.php?name='.$name);
}

2.pdf 读取

　　1.需要安装composer

　　2.在项目下面 composer require smalot/pdfparser  安装扩展 安装成功你会看到 vendor文件夹

　　

include 'vendor/autoload.php';

$parser = new SmalotPdfParserParser();
$pdf = $parser->parseFile("./upload/$name.pdf");
$text = $pdf->getText();

//读取出来的内容是字符串
// Retrieve all pages from the pdf file.
$pages  = $pdf->getPages();
 
// Loop over each page to extract text.
foreach ($pages as $page) {
    echo $text = $page->getText();
    // $text = explode("
",$text);
    // echo '<pre>';
    // print_r($text);
    // foreach($text as $kk => $vv){
    //   echo $vv.'<br>';
    // }
    
}
