Message:

I have PHP set up for a textarea that prints text from a directory to separate divs.

<?php 



$content = implode("<br /><hr class='separator'>",array_map(function ($v) {

    return file_get_contents($v);

}, glob(__DIR__ . "/posts/*.txt")));



echo '<div>';

// echo htmlentities($content);

echo '</div>';

?>

When I use htmlentities (commented out above), it disables my line break (and also my hr separator code).

I tried using \n but it also doesn't work.

How do I keep my <br /><hr class='separator'> code but still use htmlentities?

My Answer:
You can use the nl2br() function in PHP to convert newlines (\n) to HTML line breaks (
) while still using htmlentities() to escape any HTML characters. Here's how you can modify your code:

php
$content = implode("

---

", array_map(function ($v) {
return htmlentities(file_get_contents($v));
}, glob(__DIR__ . "/posts/*.txt")));

echo '

';
echo nl2br($content);
echo '

';


This way, the nl2br() function will convert the newlines in the content to HTML line breaks, while htmlentities() will escape any HTML characters to prevent code execution in the textarea.
