how to access 2d array values?

Question

do you have any idea why the "echo" in the following loop doesn't work?

while( $nl = mysql_fetch_array($Lresult) )
{
    $clkword[$i] = $nl['Word'];
    $relatedlinks[$i] = array(
        $i => array(
            "CWord" => $nl['Word'],
            "RLinks" => $nl['Link_Add']
        )
    );
    echo $relatedlinks[$i]['CWord'];
    $i++;
}

Because the way you've set it up, $relatedlinks[$i] is an array containing (at the key $i) an array containing keys "CWord" and "RLinks". In other words, you have an array inside an array inside an array, whereas what you wanted was an array inside an array. Change the line

$relatedlinks[$i]=array($i => array("CWord" => $nl['Word'],
                                    "RLinks" => $nl['Link_Add']));

to read

$relatedlinks[$i] = array( "CWord"  => $nl['Word'],
                           "RLinks" => $nl['Link_Add']
                           );
