php - Add a string after each item in Wordpress menu -

i trying add special character display » alongside each menu item in wordpress.

so example

about » contact » , on...

here's code

      <li><?php echo $children; echo '»'; ?></li> 

i expected job, puts » below list.

here's full code

      <?php       if($post->post_parent) {       $children = wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0");       $titlenamer = get_the_title($post->post_parent);       }        else {       $children = wp_list_pages("title_li=&child_of=".$post->id."&echo=0");       $titlenamer = get_the_title($post->id);       }       if ($children) { ?>        <h2 class="left_title">         <?php echo $titlenamer ?>       </h2>       <ul class="left_body">          <li><?php echo $children; echo '»'; ?></li>        </ul> 

if $children variable concatenate string using ..
you'd echo $children.'»';

however, $children array, or @ least list of items menu, require concatenating each item in list.

<li>   <?php      foreach ($children $child){       $child = $child.'»';    ?> </li>  

this trick think, i'm not sure structure of $children.

side note: use » in place of ».
