Objects with __toString() passed within methods with type declarations(either from function
arguments or return types) automagically converts it to string.
<?php
class Foo
{
public function __toString()
{
return 'foo';
}
}
class Bar
{
public function setAndGetFoo(string $foo)
{
return $foo;
}
public function getFoo(): string
{
return new Foo();
}
}
$foo = new Foo();
$bar = new Bar();
// string(3) "foo"
var_dump($bar->setAndGetFoo($foo));
// string(3) "foo"
var_dump($bar->getFoo());
