我可以用javascript编写,但我必须使用PHP。有可能吗?有一个易于使用的工具,它对这些东西非常有用: 代码应该是这样的:
$body = '
<div id="one">
<div id="two">
<div class="sub">
<span class="text"><a class="here" href="/test-aaa.php-123">ttt</a></span>
</div>
<span class="f">aa</span>
<div class="sub2">
<a class="here" href="/test-bbb.php-123">ttt</a>
<div>
<a class="here" href="/test-ttt.php-123">ttt</a>
</div>
<a class="here" href="/test-ddd.php-123">ttt</a>
</div>
<div class="sub">
<a class="here" href="/test-zzz.php-123">ttt</a>
</div>
</div>
</div>
';
替换它
HTML文件
foreach($matches[1] as $link)
{
echo $link;
}
为什么要将HTML保存到php变量?
$new_body = preg_replace('/<a [^>]*href="(.+)"/', '$1-123', $body);
echo $new_body;
preg_match_all('/<a [^>]*href="(.+)"/', $body, $matches);
var_dump($matches);
