How to remove html effect from a string using php? : <p>I am trying to display short description without any <strong>markup</strong> in read-more section. I want to display small portion of content. </p>

<p>Content Looks like:</p>

<blockquote>
  <p><strong>This is my car.</strong> <em>This may be a</em> <strike>funny</strike> <em>content</em>. This is a demo text. This is a demo text. </p>
  
  <p>This is a demo text. This is a demo text. This is a demo text. This is
  a demo text. This is a demo text. This is a demo text.</p>
</blockquote>
