foreach ($this->CsInventory as $value)

i how can i remove an empty value in the array? i try many ways but i can get any solution.. so decide to here in the forum?
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)
