Multiple Flags for json_encode()

Question

How do I use multiple flags for the php json_encode()-function?

json_encode($array, JSON_PRETTY_PRINT, JSON_UNESCAPED_UNICODE);

This doesn't work - as just the first flag will be done an the second will be ignored.

I'm voting to close this question as off-topic because the question is clearly answered through examples in the [official documentation](http://php.net/manual/en/function.json-encode.php) — Jocelyn, Aug 31 '15 at 13:58

json_encode($array, JSON_PRETTY_PRINT|JSON_UNESCAPED_UNICODE);

This will add the binary values of JSON_PRETTY_PRINT and JSON_UNESCAPED_UNICODE with the binary OR operator.

Those flags are bitmasks. I wrote about it once a long time ago here on SO.

So, basically, to use more than one option, you need to or them together

json_encode($array, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE);
