Multi-cell array

[Folks]

Hi i have sorted array as:

$my_list = array('A','B','C','D','E','F','G','H','I','...');

and i want to output as menu from array to this(sorted by column):

A - D - G
B - E - H
C - F - I

and it should be easily change with some function variable to 2 column menu (it can be two standalone function also):
or beter aim i want change also how many(or max) rows will e in one column.

A - F
B - G
C - H
D - I
E

for better imagine its XHTML menu what looklike as:
(this is one column)

 <ul class="sub_nav">
 <li><a href="http://www.example.com/alpha/">Alpha</a></li>
 <li><a href="http://www.example.com/issues/beta/">Beta</a></li>
 <li><a href="http://www.example.com/issues/gamma/">Gamma</a></li>
 <li><a href="http://www.example.com/issues/delta/">Delta</a></li>
 <li><a href="http://www.example.com/issues/immigration/">Immigration</a></li>
 <li><a href="www.example.com/issues/poverty/">Poverty</a></li>
 <li><a href="www.example.com/issues/rural/">Rural</a></li>
 <li><a href="www.example.com/issues/seniors_and_social_security/">Seniors and Social Security</a></li>
 </ul>

Where UL is column and LI is row. in my array A,B,C,D..etc are sorted (<li></li>) tags

the most close what i get is this:

$my_list = array('A','B','C','D','E','F','G','H','I'); 
$cnt = 0; 
$columns = array(); 
foreach($my_list as $list){ 
$column = ($cnt % 3) +1; 
$columns[$column] .= '<li>'.$list.'</li>'; 
$cnt++; 
} 
echo '<ul class="sub_nav">'.$columns[1].'</ul>'.PHP_EOL; 
echo '<ul class="sub_nav">'.$columns[2].'</ul>'.PHP_EOL; 
echo '<ul class="sub_nav">'.$columns[3].'</ul>'.PHP_EOL; 

but this gave me this result(sorted by row):

A - B - C
D - E - F
G - H - I

Many thanks if you know the solution im really confused.

I modified the code snippet from the link I offered slightly to adapt your array ...

$my_list = array('A','B','C','D','E','F','G','H','I'); 
  $list = ''; // initialize  
  $n = array();  
  $numRows = count($my_list);  
  if ($numRows > 0) {  
    $columns = 3;  
    $numRows = ceil($numRows/$columns);  
    foreach ($my_list as $row) {  
      $nam = htmlentities($row);  
      $n[] = "<li>{$nam}</li>";  
    }  
    $n = array_chunk($n, $numRows);  
    foreach ($n as $rows) {  
      $list .= "\n<td>\n\t<ul>\n\t\t<li>" .  
         implode("</li>\n\t\t<li>", $rows) .  
         "</li>\n\t</ul>\n</td>\n"  
      ; 
    } 
  } 
  print "<table><tr>$list</tr></table>"; 
  exit;
