How to output string using html_entities function inside text area

[slao]

I want to display the output of PHP echo statement on the browser. The result is output of htmlentities() function of PHP.

$str = "A 'quote' is <b>bold</b>";
 
// Expected Outputs: A 'quote' is &lt;b&gt;bold&lt;/b&gt;
 
echo "<textarea>".htmlentities($str)."</textarea>";
 
// Expected Outputs: A 'quote' is &lt;b&gt;bold&lt;/b&gt;
 
echo "<textarea>".htmlentities($str, ENT_QUOTES)."</textarea>";
 
 

Apparently, it is giving me

A 'quote' is <b>bold</b> 
 

inside my <textarea>

Please advise.

As far as I remember, you cannot use any HTML element inside textarea element at all. If you do they're considered and parsed as plain text.

The output that you are getting is exactly as you programmed it. I can only assume that you are looking for a WYSIWYG editor to allow you to actually see rendered markup in a "textarea." There are many options, such as TinyMCE and OpenWYSIWYG.

Just Google WYSIWYG editors.
