我必须遵循代码：

<div class="beeldengeluid-infobox" style="float: right; margin: 0em 0em 1em 1em; border: 1px #999 solid; background-color: #ffffff;">
<table border="0" cellspacing="0" cellpadding="5" width="300" summary="samenvattend persoonsoverzicht">

现在我想获取可变的图像 url。为此，我有以下代码：

  <div class="thumbinner" style="width:252px;"><img alt="" src="/images/thumb/0/03/HettyBlok.jpg/250px-HettyBlok.jpg" width="250" height="278"           class="thumbimage" /></div>

但我不知道如何得到这个。

如何获取图片网址？

我试过这个：

preg_match('@<img.+src="(.*)".*>@Uims', $cm->rev, $matches);
$src = $matches[0];
echo $src;

这对我有用，但现在我想用 div 获取 i，因为源中有多个图像，我想要正确的图像。

我试过这个：

preg_match('/<div class = "thumbinne" style="width:252px;"><img.+src="(.*)".*><\/div>/s',$cm->rev,$matches);
$src = $matches[0];
echo $src;

但这不起作用。

您可以使用 DOM 解析：

$dom = new DOMDocument;
$dom->loadHTML('<div class="thumbinner" style="width:252px;"><img alt="" src="/images/thumb/0/03/HettyBlok.jpg/250px-HettyBlok.jpg" width="250" height="278" class="thumbimage" /></div>');
$x = new DOMXPath($dom); 

foreach($x->query("//img") as $node) 
{
    echo $node->getAttribute("src");
}

另一种方式：

$dom = new DOMDocument;
$dom->loadHTML('<div class="beeldengeluid-infobox" style="float: right; margin: 0em 0em 1em 1em; border: 1px #999 solid; background-color: #ffffff;">

   </p>
   <hr />');
$x = new DOMXPath($dom); 

$images = array();

foreach($x->query("//div[contains(@class,'thumbinner')]/img") as $node) 
{
  $images[]=$node->getAttribute("src");
}

echo "<pre>";
print_r ($images);
