--TEST--
Backed enums reject duplicate int values
--FILE--
<?php
enum Foo: int {
case Bar = 0;
case Baz = 0;
}
try {
var_dump(Foo::Bar);
} catch (Error $e) {
echo $e->getMessage(), "\n";
}
try {
var_dump(Foo::Bar);
} catch (Error $e) {
echo $e->getMessage(), "\n";
}
try {
var_dump(Foo::from(42));
} catch (Error $e) {
echo $e->getMessage(), "\n";
}
try {
var_dump(Foo::tryFrom('bar'));
} catch (Error $e) {
echo $e->getMessage(), "\n";
}
?>
--EXPECT--
Duplicate value in enum Foo for cases Bar and Baz
Duplicate value in enum Foo for cases Bar and Baz
Duplicate value in enum Foo for cases Bar and Baz
Foo::tryFrom(): Argument #1 ($value) must be of type int, string given
