You should use the empty function which consider 0, "0", null... as empty values :

if (empty($sta) && empty($stb)) {

If you want to stick with your logic, consider to separate the if statements in two parts :

if (
    ($sta=="0" OR $sta=="")
    AND
    ($stb=="0" OR $stb=="")
) {

if (($sta=="0" OR $sta=="") AND ($stb=="0" OR $stb==""))

2+3*4 is not the same as (2+3)*4. The same is with OR and AND
