dump() does not throw exception as shown in the docs

[samayo]

There seems to be a mistake in the doc, right here. It shows the code in the second example throws an error, which I will copy here as:

$data = new \stdClass(); // by default objects are invalid.
Yaml::dump($data, Yaml::DUMP_EXCEPTION_ON_INVALID_TYPE); // throws an exception

echo $yaml; // { foo: bar }

I have Yaml 3.2.3 and I can't produce the same result, also the third line doesn't seem to have any effect than throw a syntax error, since it is undefined. Even if it was defined in the previous block, the output isn't as shown in the example above.

That's indeed an issue. The example is missing the $inline and $indent arguments (see #7518 for the fix).

Closing it as fixed by #7518.
