# RiskyCast
Emitted when attempting to cast an array to int or float
```php
<?php
$foo = (int) array( 'hello' );
```
## Why this is bad
The value resulting from the cast depends on if the array is empty or not and can easily lead to off-by-one errors
## How to fix
Don't cast arrays to int or float.
