删除部分字符串PHP

Question

I am working with some RSS data. I am trying to remove certain parts of the string.

The string is like this:

<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>

I only want to display:

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

or

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

I am using PHP and would like to store the value as a variable.

Your help is greatly appreciated.

Try this

$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);

Use 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);

Use strip_tags , if you want keep the p tag, add the second parameter <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>');

and the output:

ei@localhost:~$ php test.php
THIS IS THE INFO I ACTUALLY WANT TO KEEP
<p>THIS IS THE INFO I ACTUALLY WANT TO KEEP</p>

I think you are looking for text information other than xhtml tags, you can do that by strip_tags($text) in php-example-

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