我有这个代码

<input type=hidden name="code1" value="AA-T5301">
    <tr>
        <td align=left valign=middle class="stdtext">
            AA-T5301
        </a>
        </td>
        <td valign=middle align=left class="stdtext">
            <a onMouseOver="window.status='See the more info on '; return true"
                HREF="product.asp?ms=&dept_id=322&sku=32&nav=">
                Grapeseed Oil 150ml
            </A>
        </td>
        <td valign=middle align=right class="stdtext">Order Now</td>
        <td valign=middle align=right class="stdtext">

            £2.04
        </td>
        <td valign=middle align=right class="stdtext">

        </td>
    </tr>
    <input type=hidden name="code2" value="AA-T5302">
        <tr>
            <td align=left valign=middle class="stdtext">

                </td>
            </tr>

我怎样才能将信息提取到一个数组中，所以我有这样的东西..

product_code_array=(AA-T5301,AA-T5302,AA-T530);

RRP_array=(3.04,6.46,1.75);

price_array=(2.04,4.33,1.17);

注意：一次页面上可能有 3 个以上的项目，或者可能只有 1 个

4

您可以尝试使用DOMDocument类，但您必须修复您的 html。您有结束链接标签 ( </a>) 没有任何开始链接标签 ( <a href="">)

首先看一下这段代码：

$dom = new domDocument;
$dom->strictErrorChecking = false;
$dom->preserveWhiteSpace = true;        
@$dom->loadHTML($html-data);
$trs=$dom->getElementsByTagName('tr');
foreach ($trs as $tr) 
{
   // now go through those elements. lookup the PHP doc on the DOM parser
   // You can iterate through sub-elements (like the 'td') just like through the 'tr'
}

你也可以直接去或只是你需要它。根据您的页面布局，您可能希望使用“更高”节点，以便根据标签参数或标签位置了解您的位置。
