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.
