使用php进行数据解析和检索

假设我们在网页中有以下结构。如何使用php检索以下信息？ 某物 XAXAXA-SASASA 2-1 扎扎-卡卡卡2-2

<th class='black' colspan='6'>something</th>
<tr class=''>
        <td bgcolor = '#272727' width = 40%>XAXAXA</td>
        <td bgcolor = '#272727'  width = '5%'> - </td>
        <td bgcolor = '#272727' width = '40%'>SASASASA</td>
        <td bgcolor = '#272727'  width = '5%'>2</td>
        <td bgcolor = '#272727'  width = '5%'> - </td>
        <td bgcolor = '#272727' width = '5%'>1</td>
    </tr>
<tr class=''>
        <td bgcolor = '#484848' width = 40%>ZAZAZAZA</td>
        <td bgcolor = '#484848'  width = '5%'> - </td>
        <td bgcolor = '#484848' width = '40%'>CACACACA</td>
        <td bgcolor = '#484848'  width = '5%'>2</td>
        <td bgcolor = '#484848'  width = '5%'> - </td>
        <td bgcolor = '#484848' width = '5%'>2</td>
    </tr>

什么 XAXAXA - 萨萨萨 2. - 1. 扎扎 - 卡卡卡 2. - 2.

您可以使用正则表达式来匹配这样的模式。preg_match（）函数是一个很好的起点。

$sourcestring="your source string";
preg_match_all('/<th[^>]*>([^<]*).*?<td[^>]*>([^<]*).*?<td[^>]*>([^<]*).*?<td[^>]*>([^<]*).*?<td[^>]*>([^<]*).*?<td[^>]*>([^<]*).*?<td[^>]*>([^<]*).*?<td[^>]*>([^<]*).*?<td[^>]*>([^<]*).*?<td[^>]*>([^<]*).*?<td[^>]*>([^<]*).*?<td[^>]*>([^<]*).*?<td[^>]*>([^<]*)/is',$sourcestring,$matches);
echo "<pre>".print_r($matches,true);

$sourcestring=“您的源字符串”；
preg_match_all（'/]*>（[^（[^（[^（[^（[^（[^（[^（[^（[^（[^（[^（[^）您可以使用DOMDocument进行此操作，非常简单：
