Question

我需要替换多个html标签。示例代码如下：

$html = "<p>
  Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.
  <visualcontent imgid='1' type='jpg'></visualcontent>
  Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.
  <visualcontent imgid='2' type='png'></visualcontent>
</p>";

我需要的输出是：

$html = "<p>
  Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.
  <img src='1.jpg'>

  <img src='2.png'>
</p>";

如果你看到：

<visualcontent imgid='x' type='x'></visualcontent>

被替换为图片标记。我对如何做到这一点毫无头绪。请帮忙。

  <visualcontent imgid='2' type='png'></visualcontent>
</p>";

$html = str_get_html($htmlString);

foreach($html->find('visualcontent') as $v){
    $src = $v->imgid;
    $type = $v->type;

    $v->outertext = '<img src="'. $src .'.'.$type.'" />';
}

$output = $html->save();

print $output;

$html->clear();
unset($html);
