# Xdigit

- `Xdigit()`
- `Xdigit(string ...$additionalChars)`

Validates whether the input is an hexadecimal number or not.

```php
v::xdigit()->validate('abc123'); // true
```

Notice, however, that it doesn't accept strings starting with 0x:

```php
v::xdigit()->validate('0x1f'); // false
```

Update documentation 2015-01-30 09:40:06 +01:00			`# Xdigit`

Change how documentation of rules are presented Rules are not always used from the alias `v`, neither called staticaly. 2017-03-27 14:47:07 +02:00			- `Xdigit()`
Use variadics "AbstractFilterRule" rule Since the library doesn't need to give support to version 5.4 or less of PHP using variadics in the constructor of "AbstractFilterRule" seems better than doing the whole validation. This commit will also apply the contribution guidelines to "AbstractFilterRule" and use a better naming for it.
