ACF Fields - Array Loop - IF Statement

I am using this code that returns an array:

$values = get_field('sp_specialism', $prev_id);var_dump($values);

The output of the array is:

array(3) { [0]=> string(4) "Asia" [1]=> string(6) "Canada" [2]=> string(9) "Caribbean" }

I am trying to loop through the array and output Asia Canada Caribbean as list items

if($values) { echo '<ul>'; foreach($values as $value) { echo '<li>' . $value . '</li>'; } echo '</ul>'; }

However my if statement is erroring out. Not sure why this happens.

I am using this within another piece of code like this:

$string = "<span class=\"bkcards-exp\">" . get_field('sp_location', $prev_id) . "</span><span class=\"bkcards-left\">" . if($values) { echo '<ul>'; foreach($values as $value) { echo '<li>' . $value . '</li>'; } echo '</ul>'; } . "</span>"

You can't concatenate an if statement with a string. Instead, you can divide the string into multiple different statements as shown in the following snippet.

$string = '<span class="bkcards-exp">' . 
               get_field('sp_location', $prev_id) . 
          '</span><span class="bkcards-left">';

if($values) { 
    $string .= '<ul>'; 
    foreach($values as $value) { 
        $string .= '<li>' . $value . '</li>'; 
    } 
    $string .= '</ul>';
}

$string .= '</span>';
