Note that booleans are scalars. Full stop.
| is_scalar($v) | Result |
|---|---|
| "foo" | true |
| "" | true |
| null | true |
| 0 | true |
| 0.5 | true |
| true | true |
| false | true |
| new stdclass() | false |
| array() | false |
Note that phutil_nonempty_scalar() was designed just to tell
whenever a scalar is "empty" or not. So it must not explode
when receiving a valid scalar.
So the question is not whenever a boolean is a scalar or not,
but whenever is empty or not. But also this is a clear fact:
| $v | is_scalar($v) | !is_empty($v) | if(strlen($v)) |
|---|---|---|---|
| true | true | true | true |
| false | true | false | false |
In short, now the function does not explode anymore with bool
values. Instead, it says whenever are empty or not.
In bold the exact changes:
| Value | phutil_nonempty_scalar($v) |
|---|---|
| "foo" | true |
| "" | false |
| null | false |
| 0 | true |
| 0.5 | true |
| obj with tostring | true |
| obj withno tostr. | Exception |
| array() | Exception |
| true | |
| false | |
