videni wants to merge 1 commit into echo58:master from videni:patch-1

since these options are required, I think it is necessary to make sure they are not empty.

Thanks. From PHP manual:

The following things are considered to be empty:

"" (an empty string)
0 (0 as an integer)
0.0 (0 as a float)
"0" (0 as a string)
NULL
FALSE
array() (an empty array)
$var; (a variable declared, but without a value)

Some options may use above values, so we cannot restrict options not empty.
Right?
