How can PHP code be stored in a variable and displayed within a <textarea> element for editing purposes?

To store PHP code in a variable and display it within a <textarea> element for editing purposes, you can use htmlentities() function to encode the PHP code and then echo it within the <textarea> element. This will prevent the PHP code from being executed and display it as plain text for editing. 

&lt;?php
// PHP code to be stored in a variable
$php_code = &quot;&lt;?php echo &#039;Hello, World!&#039;; ?&gt;&quot;;

// Encode the PHP code for display within &lt;textarea&gt;
$encoded_php_code = htmlentities($php_code);

// Display the encoded PHP code within &lt;textarea&gt;
echo &#039;&lt;textarea&gt;&#039; . $encoded_php_code . &#039;&lt;/textarea&gt;&#039;;
?&gt;
