removing array empty value

Question

 foreach ($this->CsInventory as $value)
    {

     print_r($value) // print 1
    $vname = $value[] = $value['VesselName']; 
    $total = $value[] = $value['Total']; 
    $Box = $value[] = $value['Box']; 

        print_r($value); // print 2

        $rdata .= '<td>'.$vname.'</td>
          <td>'.$total.'</td>
             <td>'.$Box.'</td>';

I'd try to reduce effort.

foreach ($this->CsInventory as $value) 
    { 
        foreach ($value as $key => $item)
        {
             $value[] = $item;
             $rdata .= "<td>$item</td>";

        }

       print_r($value)                  
    }

As a general comment, not sure why you're adding anonomous values back to the $values stack, might be better to use a different array.

If you have specific array elements you want to get rid of, you can use unset($array[$key]);

You could also prevent them getting into the array in the first place by using

if($value['VesselName']) {$vname = $value[] = $value['VesselName'];}

instead of simply

$vname = $value[] = $value['VesselName'];

function array_remove_empty($arr){
    $narr = array();
    while(list($key, $val) = each($arr)){
        if (is_array($val)){
            $val = array_remove_empty($val);
            // does the result array contain anything?
            if (count($val)!=0){
                // yes :-)
                $narr[$key] = $val;
            }
        }
        else {
            if (trim($val) != ""){
                $narr[$key] = $val;
            }
        }
    }
    unset($arr);
    return $narr;
}

array_remove_empty(array(1,2,3, '', array(), 4)) => returns array(1,2,3,4)
