### Description
The following code:
```php
<?php
$s = "-0b11111111111111111111111111111111111111111111111111111111111111111111111111111";
$v1 = intval($s, 2);
var_dump($v1);
$v2 = intval($s);
var_dump($v2);
var_dump((int) $s);
```
Resulted in this output:
```
int(-9223372036854775808)
int(0)
int(0)
```
But I expected this output instead:
```
int(-9223372036854775808)
int(-9223372036854775808)
int(0)
```
Similarly, if we use `
$base = 16`
Note the `0o` prefix is not supported (which is what initially led me down this rabbit
hole).
