You can use array_filter to remove empty array elements

$arr = array('s','','s','','a','i','',2,'',2);

$arr = array_filter($arr);

echo "<pre>";
print_r( $arr );
echo "</pre>";

This will result to:

Array
(
    [0] => s
    [2] => s
    [4] => a
    [5] => i
    [7] => 2
    [9] => 2
)

Or you can use trim as callback if there are multiples spaces. Like:

$arr = array('s','   ','s','    ','a','i','   ',2,'',2);

$arr = array_filter($arr,'trim');

echo "<pre>";
print_r( $arr );
echo "</pre>";

Will get the same result.
