|
|
---
|
|
|
|
# Description
|
|
|
|
Since [PHP 8.0](20201109133834-php_8_0), the stringable interface[^1] is
|
|
automatically added to classes that implement the `__toString()` method
|
|
|
|
# Syntax
|
|
|
|
``` php
|
|
class Foo
|
|
{
|
|
public function __toString(): string
|
|
{
|
|
return 'foo';
|
|
}
|
|
}
|
|
|
|
function bar(string|Stringable $stringable) { /* … */ }
|
|
|
|
bar(new Foo());
|
|
bar('abc');
|
|
```
|
