Are there specific PHP functions that can be used to convert < and > symbols to &lt; and &gt; within textareas?

To convert < and > symbols to &lt; and &gt; within textareas in PHP, you can use the htmlspecialchars function. This function will convert special characters to their HTML entities, preventing any potential security vulnerabilities such as cross-site scripting (XSS) attacks. 

$text = $_POST[&#039;textarea_input&#039;]; // Assuming textarea input is submitted via POST
$safe_text = htmlspecialchars($text, ENT_QUOTES);
echo &quot;&lt;textarea&gt;$safe_text&lt;/textarea&gt;&quot;;
