删除部分字符串PHP

我正在处理一些RSS数据。我正在尝试删除字符串的某些部分。删除部分字符串PHP

的字符串是这样的：

<description><![CDATA[<div style="float:right;margin:0 0 1ex 1ex"><a href="/link/123" rel="nofollow" title="Link: www.example.com/testing-information"><img src="http://www.example.com/a/100/1000.jpg?hash=a38232k" alt="More info here"/></a></div><p>THIS IS THE INFO I ACTUALLY WANT TO KEEP</p>

我只想显示：

**THIS IS THE INFO I ACTUALLY WANT TO KEEP**

或

**<p>THIS IS THE INFO I ACTUALLY WANT TO KEEP</p>**

我使用PHP和想存储的值一个变量。

非常感谢您的帮助。

使用'strip_tags($text) strip_tags' –

看起来像XML的一部分，尝试使用[simplexml_load_string]（http://www.php.net/manual/en/function.simplexml-load-string.php）上的完整字符串 – bansi

使用strip_tags，如果你想保持p标签，添加第二个参数<p>

<?php 
     //without p tag 
     echo strip_tags('<description><![CDATA[<div style="float:right;margin:0 0 1ex 1ex"><a href="/link/123" rel="nofollow" title="Link: www.example.com/testing-information"><img src="http://www.example.com/a/100/1000.jpg?hash=a38232k" alt="More info here"/></a></div><p>THIS IS THE INFO I ACTUALLY WANT TO KEEP</p>'); 
     echo "\n"; 
     //with p tag 
     echo strip_tags('<description><![CDATA[<div style="float:right;margin:0 0 1ex 1ex"><a href="/link/123" rel="nofollow" title="Link: www.example.com/testing-information"><img src="http://www.example.com/a/100/1000.jpg?hash=a38232k" alt="More info here"/></a></div><p>THIS IS THE INFO I ACTUALLY WANT TO KEEP</p>', '<p>');

和输出：

[email protected]:~$ php test.php 
THIS IS THE INFO I ACTUALLY WANT TO KEEP 
<p>THIS IS THE INFO I ACTUALLY WANT TO KEEP</p>

试试这个

$str = '<description><![CDATA[<div style="float:right;margin:0 0 1ex 1ex"><a href="/link/123" rel="nofollow" title="Link: www.example.com/testing-information"><img src="http://www.example.com/a/100/1000.jpg?hash=a38232k" alt="More info here"/></a></div><p>THIS IS THE INFO I ACTUALLY WANT TO KEEP</p>'; 
preg_match('~<p>(.*?)</p>~', $str, $matches); 
var_dump($matches);

使用strip_tags：

$text = '<description><![CDATA[<div style="float:right;margin:0 0 1ex 1ex"><a href="/link/123" rel="nofollow" title="Link: www.example.com/testing-information"><img src="http://www.example.com/a/100/1000.jpg?hash=a38232k" alt="More info here"/></a></div><p>THIS IS THE INFO I ACTUALLY WANT TO KEEP</p>'; 
echo strip_tags($text);

我认为你正在寻找比XHTML标签等文本信息，你可以做到这一点在PHP的示例 -

$text = '<description><![CDATA[<div style="float:right;margin:0 0 1ex 1ex"><a href="/link/123" rel="nofollow" title="Link: www.example.com/testing-information"><img src="http://www.example.com/a/100/1000.jpg?hash=a38232k" alt="More info here"/></a></div><p>THIS IS THE INFO I ACTUALLY WANT TO KEEP</p>'; 
echo strip_tags($text); 
echo "\n";
