# ImplicitToStringCast
Emitted when implicitly converting an object with a `__toString` method to a string
```php
2020-03-21 00:13:46 +01:00
<?php
2020-03-19 17:32:49 +01:00
class A {
public function __toString() {
return "foo";
}
}
function takesString(string $s) : void {}
takesString(new A);
```

## How to fix
2020-03-21 05:39:00 +01:00
You can add an explicit string cast:
```php
<?php
...
takesString((string) new A);
```
