# Xdigit
|
||
|
|
|
||
|
|
- `v::xdigit()`
|
||
|
|
|
||
|
|
Accepts an hexadecimal number:
|
||
|
|
|
||
|
|
```php
|
||
|
|
v::xdigit()->validate('abc123'); // true
|
||
|
|
```
|
||
|
|
|
||
|
|
Notice, however, that it doesn't accept strings starting with 0x:
|
||
|
|
|
||
|
|
```php
|
||
|
|
v::xdigit()->validate('0x1f'); // false
|
||
|
|
```
|
||
|
|
|
||
|
