Question

我想知道你是否可以将html标签变成数组。

   <title>aa</title>
  <link>http://dailynews.yahoo.co.jp/fc/domestic/nuke_disaster_prevention/?id=6170385</link>
    <pubDate>Wed, 12 Aug 2015 17:14:19 +0900</pubDate>
    <guid isPermaLink="false">yahoo/news/topics/6170385</guid>
    </item>
    <item>
    <title>bb</title>
    <link>http://dailynews.yahoo.co.jp/fc/local/okinawa_us_armed_forces/?id=6170398</link>
    <pubDate>Wed, 12 Aug 2015 17:57:37 +0900</pubDate>
    <enclosure length="133" url="http://i.yimg.jp/images/icon/photo.gif" type="image/gif">
    </enclosure>
    <guid isPermaLink="false">yahoo/news/topics/6170398</guid>
    </item>

我有这些html标签，我想通过标签（按标题，链接，描述等）将其转换为数组是否可能，因为我希望它是一个数组，所以我可以将它插入我的数据库表。

Answer 1

您可以使用以下示例来完成此操作。然后将字符串转换为数组

<?php
 $myhtml = <<<EOF
 ?>
 <html>
 <head>
 <title>My Page</title>
 </head>
 <body>
 <p><a href="/mypage1">Hello World!</a></p>
 <p><a href="/mypage2">Another Hello World!</a></p>
 </body>
 </html><?php
 EOF;

 $doc = new DOMDocument();
 $doc->loadHTML($myhtml);

 $tags = $doc->getElementsByTagName('a');

 foreach ($tags as $tag) {
   echo $tag->getAttribute('href').' | '.$tag->nodeValue."\n";
 }

 ?>

您的内容看起来像XML？您可以使用simplexml_load_string()将XML字符串解释为对象：

<?php
$mytext ='
<items>

    <item>
        <title>aa</title>
        <link>http://dailynews.yahoo.co.jp/fc/domestic/nuke_disaster_prevention/?id=6170385</link>
        <pubDate>Wed, 12 Aug 2015 17:14:19 +0900</pubDate>
        <guid isPermaLink="false">yahoo/news/topics/6170385</guid>
    </item>

    <item>
        <title>bb</title>
        <link>http://dailynews.yahoo.co.jp/fc/local/okinawa_us_armed_forces/?id=6170398</link>
        <pubDate>Wed, 12 Aug 2015 17:57:37 +0900</pubDate>
        <enclosure length="133" url="http://i.yimg.jp/images/icon/photo.gif" type="image/gif">
        </enclosure>
        <guid isPermaLink="false">yahoo/news/topics/6170398</guid>
    </item>

</items>';

$xml = simplexml_load_string($mytext);
print_r($xml);
 ?>

<强>输出：

SimpleXMLElement Object
(
    [item] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [title] => aa
                    [link] => http://dailynews.yahoo.co.jp/fc/domestic/nuke_disaster_prevention/?id=6170385
                    [pubDate] => Wed, 12 Aug 2015 17:14:19 +0900
                    [guid] => yahoo/news/topics/6170385
                )

            [1] => SimpleXMLElement Object
                (
                    [title] => bb
                    [link] => http://dailynews.yahoo.co.jp/fc/local/okinawa_us_armed_forces/?id=6170398
                    [pubDate] => Wed, 12 Aug 2015 17:57:37 +0900
                    [enclosure] => SimpleXMLElement Object
                        (
                            [@attributes] => Array
                                (
                                    [length] => 133
                                    [url] => http://i.yimg.jp/images/icon/photo.gif
                                    [type] => image/gif
                                )

                        )

                    [guid] => yahoo/news/topics/6170398
                )

        )

)

遍历对象并将值插入数据库

foreach($xml as $item) {

    //Insert into database
    echo $item->title;
    echo $item->link;

}
