我正在使用以下代码，并且特定 pdf 页面的所有内容都以正确的方式转换。但是，如果 pdf 页面中间有任何图像，则 HTML 中的该图像显示在顶部。

PHP代码：

umask(0);
$output = shell_exec('pdftohtml create.pdf create.html');

编辑：

请检查我用于此的 pdf：https ://www.dropbox.com/s/6uy9wq27ff00n0x/create.pdf?dl=0

在此 PDF 中，图像在 2 行之后。

// 加载转换后的html页面。shell_exec 将 's' 添加到 html 文件，creates.html

$html = file_get_contents('creates.html');
print_r($html);

// 输出

<!DOCTYPE html><html>
<head>
</head>
<body>
<img src="/var/www/html/pdf-sign/public/converted_path/create-1_1.png"/><br/>

现在看看

<img src="/var/www/html/pdf-sign/public/converted_path/create-1_1.png"/>

就在身体标签之后。这意味着图像被移到顶部以代替第三行。

我也遇到过这种问题。我有一个解决方案。首先，您需要将 pdf 文档转换为 XML

$output = shell_exec('pdftohtml -xml create.pdf create.xml');

XML 输出如下所示

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE pdf2xml SYSTEM "pdf2xml.dtd">
<pdf2xml producer="poppler" version="0.33.0">
<page number="1" position="absolute" top="0" left="0" height="1262" width="892">
<fontspec id="0" size="16" family="Times" color="#000000"/>
<image top="117" left="51" width="424" height="96" src="converted_path/create1.jpg"/>
<text top="57" left="99" width="144" height="16" font="0">Test document PDF</text>
</page>
</pdf2xml>

然后你把这个 XML 字符串转换成一个对象

$xml = simplexml_load_string($xmlContent);

之后，您需要使用 xml 属性顶部值测量确切的图像位置，如下所示

$pg = 0;
foreach($xml->page as $page) {
        foreach ($page as $e) {
            $all_attribute[$pg][(int)$e['top']] = $e;
        }
        $pg++;
    }

找出所有属性的最高值后，根据 array[key] 对值进行排序

foreach($all_attribute as $page) {
        ksort($page);
}

当所有属性都根据 xml 最高值排序时，只需像下面这样处理 html

foreach($xml->page as $page) {
  foreach($page as $p){
      if($p->getName() == 'image'){
         <img width="'.$p['width'].'" height="'.$p['height'].'" src="'.$p['src'].'" >
      }
  }
}

我认为它可以帮助您
您还可以管理您的文本字体
xml 存储在 fontspec 属性中的所有字体并提供一个 id

<fontspec id="0" size="16" family="Times" color="#000000"/>

并且此 id 在文本属性字体值中调用

<text top="57" left="99" width="144" height="16" font="0">

现在借助这些值，您需要处理如下字体

$font = [];
    foreach($xml->page as $page) {
        foreach ($page as $e) {
            if($e->getName() == 'fontspec'){
                $font[(int)$e['id']]['family'] = (string)$e['family'];
                $font[(int)$e['id']]['size'] = (string)$e['size'];
                $font[(int)$e['id']]['color'] = (string)$e['color'];
            }
        }
    }

之后你需要把这个字体处理成html

foreach($page as $p){
            if($p->getName() == 'text'){
                $ind = (int)$p['font'];
                $font_size = $font[$ind]['size'];
                $font_color = $font[$ind]['color'];
                $font_family = $font[$ind]['family'];
                '<span style="font-size:'.$font_size.'px;color:'.$font_color.';font-family:'.$font_family.'; font-weight: 900;">'.(string)$p.'</span>=';
          }
}

而不是 print_r 只是打印文件的内容：

<?php
echo file_get_contents('creates.html');
?>

并确保这是并且仅在您的 php.ini 中输出。如果您在开始时有一些 html，它将破坏布局。
