IMO, use array_map()

$sal=0;
$sal = array_sum(array_map(
                 function($item){
                     return $item->Salary;
                 }, 
       $variable));

I'm assuming you're referring to concatenation, since you instantiate $sal = "" (as a string). Use the concatenating assignment operator.

$sal = "";
foreach($variable as $key => $value){
   $sal .= $value->Salary;
}
echo $sal;

try this

$sal = 0;
foreach($variable as $key => $value){
   $sal += $value->Salary;
}
echo $sal;
