As many others have said, <code>htmlentities()</code> will do the trick... but it will look like shit.

Wrap it up with a <code>&lt;pre&gt;</code> tag and you'll preserve your indentation.

<pre><code>echo '&lt;pre&gt;';
echo htmlspecialchars($YOUR_HTML);
echo '&lt;/pre&gt;';
</code></pre>

You should use <a href="http://id.php.net/manual/en/function.htmlspecialchars.php" rel="nofollow noreferrer"><code>htmlspecialchars</code></a>. It replaces characters as below:
<ul>
<li><code>&amp;</code> (ampersand) becomes <code>&amp;amp;</code></li>
<li><code>&quot;</code> (double quote) becomes <code>&amp;quot;</code> when ENT_NOQUOTES is not set.</li>
<li><code>'</code> (single quote) becomes <code>&amp;#039;</code> only when ENT_QUOTES is set.</li>
<li><code>&lt;</code> (less than) becomes <code>&amp;lt;</code></li>
<li><code>&gt;</code> (greater than) becomes <code>&amp;gt;</code></li>

You can use htmlentities when echoing to the browser, this will show the tag rather than have html interpret it.

See here <a href="http://uk3.php.net/manual/en/function.htmlentities.php" rel="nofollow">http://uk3.php.net/manual/en/function.htmlentities.php</a>

Example:

<pre><code> echo htmlentities("&lt;strong&gt;Look just like this line - so then know how to type it&lt;/strong&gt;"); 
</code></pre>

Output:

<pre><code>&lt;strong&gt;Look just like this line - so then know how to type it&lt;/strong&gt;

I have an input form on my website where HTML is allowed and I'm trying to add instructions about the use of HTML tags. I'd like the text to

<pre><code>&lt;strong&gt;Look just like this line - so then know how to type it&lt;/strong&gt;
</code></pre>

But so far all I get is:

Look just like this line - so then know how to type it

How can I show the tags so people know what to type?

How to display HTML tags as plain text
