This is an inspiration from this question: PHP Parse HTML code

您可以使用 http://php.net/manual/en/class.domelement.php

以下是示例代码;

And here's the sample code;

$str = '<div class="address_row">
  <span class="address1">239 House</span>
  <span class="address2">Street South</span>
</div>';

$DOM = new DOMDocument;
$DOM->loadHTML($str);

// all span elements
$items = $DOM->getElementsByTagName('span');
$span_list = array();

for($i = 0; $i < $items->length; $i++) {
    $item = $items->item($i);
    $span_list[$item->getAttribute('class')] = $item->nodeValue;
}
extract($span_list);

echo $address1; // 239 House
echo $address2; // Street South
