Most methods that consume strings will have an empty value for a
stringable. Despite
empty() always saying a stringable is not empty.
<?php
class Uuid implements Stringable {
private string $value;
public function __construct(string $value) {
$this->value = $value;
}
public function __toString(): string {
return $this->value;
}
}
$x = new Uuid('asdf');
var_dump(['b'=>$x]);
/*
array(1) {
["b"]=>
object(Uuid)#1 (1) {
["value":"Uuid":private]=>
string(4) "asdf"
}
} */
var_dump(['a'=>$x]); // "{"a":{}}"
?>
