Explode Textarea each line in list item

Question

I am trying to get each new line of textarea as a list item with explode and foreach. I have tried \\n, \\n\\r, \\r\\n and PHP_EOL but nothing works. Here is my function

function dt_explode_list($option,$explode_key,$ul_class) {

    $tacs = explode($explode_key, get_option($option));

    echo '<ul class="'.$ul_class.'">';

    foreach ($tacs as $tac) {

        echo '<li>'.$tac.'</li>';   

    }

    echo '</ul>';

}

Calling with this

<?php dt_explode_list('dt_condition_apply','\n','tick-list'); ?>

Answer 1

New lines need to be in double quotes

<?php dt_explode_list('dt_condition_apply',"\n",'tick-list'); ?>

See "Double Quoted" http://php.net/manual/en/language.types.string.php
