如何用PHP从HTML字符串中仅提取文本？

Question

I want to extract only text from a php string.

This php string contains html code like tags or etc.

So I only need a simple text from this string.

This is the actual string:

<div class="devblog-index-content battlelog-wordpress">
<p><strong>The celebration of the Recon class in our second </strong><a href="http://blogs.battlefield.com/2014/10/bf4-class-week-recon/" target="_blank">BF4 Class Week</a><strong> continues with a sneaky stroll down memory lane. Learn more about how the Recon has changed in appearance, name and weaponry over the years&hellip;</strong></p>

<p>&nbsp;</p>

<p style="text-align:center"><a href="http://eaassets-a.akamaihd.net/battlelog/prod/954660ddbe53df808c23a0ba948e7971/en_US/blog/wp-content/uploads/2014/10/bf4-history-of-recon-1.jpg?v=1412871863.37"><img alt="bf4-history-of-recon-1" class="aligncenter" src="http://eaassets-a.akamaihd.net/battlelog/prod/954660ddbe53df808c23a0ba948e7971/en_US/blog/wp-content/uploads/2014/10/bf4-history-of-recon-1.jpg?v=1412871863.37" style="width:619px" /></a></p>

I want to show this from the string:

The celebration of the Recon class in our second BF4 Class Week continues with a sneaky stroll down memory lane. Learn more about how the Recon has changed in appearance, name and weaponry over the years…

Actually this text will be placed in meta description tag so I don't need any HTML in meta tag. How can I perform this? Any ideas and thoughts about this technique ?

Answer 1

You may try:

echo(strip_tags($your_string));

More info here: http://php.net/manual/en/function.strip-tags.php

Answer 2

Another option is to use Html2Text. It will do a much better job than strip_tags, especially if you want to parse complicated HTML code.

Extracting text from HTML is tricky, so your best bet is to use a library built for this purpose.

https://github.com/mtibben/html2text

Install using composer:

composer require html2text/html2text

Basic usage:

$html = new \Html2Text\Html2Text('Hello, &quot;<b>world</b>&quot;');

echo $html->getText();  // Hello, "WORLD"

Answer 3

Adding another option for someone else who may need this, the Stringizer library might be an option, see Strip Tags .
