d2198dfd01There's more value on showing how `assert()` displays the validation messages than simply showing if `isValid()` returns `true` or `false`. However, that increases the chances of having outdated documentation, so I created a doc linter that updates the Markdown files with the correct message.

# Digit
|
|
|
|
- `Digit()`
|
|
- `Digit(string ...$additionalChars)`
|
|
|
|
Validates whether the input contains only digits.
|
|
|
|
```php
|
|
v::digit()->assert('020 612 1851');
|
|
// → "020 612 1851" must contain only digits (0-9)
|
|
|
|
v::digit(' ')->assert('020 612 1851');
|
|
// Validation passes successfully
|
|
|
|
v::digit()->assert('172.655.537-21');
|
|
// → "172.655.537-21" must contain only digits (0-9)
|
|
|
|
v::digit('.', '-')->assert('172.655.537-21');
|
|
// Validation passes successfully
|
|
```
