# IntVal
|
|
|
|
- `IntVal()`
|
|
|
|
Validates if the input is an integer, allowing leading zeros and other number bases.
|
|
|
|
```php
|
|
v::intVal()->assert('10');
|
|
// Validation passes successfully
|
|
|
|
v::intVal()->assert('089');
|
|
// Validation passes successfully
|
|
|
|
v::intVal()->assert(10);
|
|
// Validation passes successfully
|
|
|
|
v::intVal()->assert(0b101010);
|
|
// Validation passes successfully
|
|
|
|
v::intVal()->assert(0x2a);
|
|
// Validation passes successfully
|
|
```
|
|
|
|
This validator 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 validator validates, without having surprises.
|
|
|
|
```php
|
|
v::intVal()->assert(true);
|
|
// → `true` must be an integer
|
|
|
|
v::intVal()->assert('89a');
|
|
// → "89a" must be an integer
|
|
```
|
|
|
|
Even though PHP can cast the values above as integers, this validator will not
|
|
consider them as valid.
