7c681fec66I ran the `bin/console spdx --fix` with different strategies for different files. For most of the core classes, since they've been drastically rebuilt, I've run it with the `git-blame` strategy, for for the `src/Validators`, in which the API changed completely but the logic remains the same, I use the `git-log` strategy.

# FalseVal
|
|
|
|
- `FalseVal()`
|
|
|
|
Validates if a value is considered as `false`.
|
|
|
|
```php
|
|
v::falseVal()->assert(false);
|
|
// Validation passes successfully
|
|
|
|
v::falseVal()->assert(0);
|
|
// Validation passes successfully
|
|
|
|
v::falseVal()->assert('0');
|
|
// Validation passes successfully
|
|
|
|
v::falseVal()->assert('false');
|
|
// Validation passes successfully
|
|
|
|
v::falseVal()->assert('off');
|
|
// Validation passes successfully
|
|
|
|
v::falseVal()->assert('no');
|
|
// Validation passes successfully
|
|
|
|
v::falseVal()->assert('0.5');
|
|
// → "0.5" must evaluate to `false`
|
|
|
|
v::falseVal()->assert('2');
|
|
// → "2" must evaluate to `false`
|
|
