# IntVal

- `IntVal()`

Validates if the input is an integer, allowing leading zeros and other number bases.

```php
v::intVal()->validate('10'); // true
v::intVal()->validate('089'); // true
v::intVal()->validate(10); // true
v::intVal()->validate(0b101010); // true
v::intVal()->validate(0x2a); // true
```

This rule will consider as valid any input that PHP can convert to an integer,
but that does not contain non-integer values. That way, one can safely use the
value this rule validates, without having surprises.

```php
v::intVal()->validate(true); // false
v::intVal()->validate('89a'); // false
```

Even though PHP can cast the values above as integers, this rule will not
consider them as valid.
