Answer 1

HTML can't be parsed using just regular expressions: Using regular expressions to parse HTML: why not?

I recommend looking into using a library for HTML parsing. There are free ones out there, such as http://htmlpurifier.org/ .

Answer 2

This Question has been answered several Times: remove html tags

But a little bit detailed you can see below.

Based on the Official PHP Documentation : http://www.php.net//manual/en/function.strip-tags.php

You should use Strip Tags:

<?php
$text = '<p>Test paragraph.</p><!-- Comment --> <a href="#fragment">Other text</a>';
echo strip_tags($text);
echo "\n";

// Allow <p> and <a>
echo strip_tags($text, '<p><a>');
?>

OutPut:

Test paragraph. Other text
<p>Test paragraph.</p> <a href="#fragment">Other text</a>
