How to Explode a Textarea Field and Echo each line separately, wrapped with HTML

by

Need to take an advanced custom field textarea and display it in my template by breaking out each line separately. I want to wrap each line of the textarea with HTML, like an <li>.

I’ve tried the following, but it’s just not working:

if (isset($instruction_textarea)){
    $arry=explode( "\r\n", $instruction_textarea );
}
for ($i = 0; $i <= count($arry); $i++){
    echo (trim($arry[$i])+"<br/>");
}

I would try something like this:

$lines = explode("\n", $instruction_textarea); // or use PHP PHP_EOL constant
if ( !empty($lines) ) {
  echo '<ul>';
  foreach ( $lines as $line ) {
    echo '<li>'. trim( $line ) .'</li>';
  }
  echo '</ul>';
}

It should work.
