How to use regular matching to remove html in php

Operating system for this tutorial: Windows 10 system, php8.1.3 version, Dell G3 computer.

php uses regular matching to remove html as follows:

First define a string containing HTML tags.

$html_string = "<div><h2>Hello World</h2><p>This is <strong>P HP</strong>.</p></div>";
Copy after login

The above code defines a string with standard HTML tags. Our goal is to remove all HTML markup and leave only plain text content.

Use the preg_replace() function to remove all HTML tags in the string.

The following code demonstrates how to use the preg_replace() function to remove HTML tags.

$plain_text = preg_replace(&#39;/<[^<]+>/&#39;, &#39;&#39;, $html_string);echo $plain_text;
Copy after login

In the above code, we define a preg_replace() function with a regular expression pattern. The regular expression pattern `

/<[^<]+>/
Copy after login

` means to find any substring starting with "<" and ending with ">" and replacing it with an empty string. This will remove all HTML tags.

Finally, we can output a string that does not contain HTML tags on the screen.
