Code example

`
const MY_SIMPLE_JSON_FLAGS = JSON_THROW_ON_ERROR;

const MY_JSON_FLAGS = JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE | JSON_THROW_ON_ERROR |
JSON_PRESERVE_ZERO_FRACTION;

const MY_JSON_LOG_FLAGS = MY_JSON_FLAGS | JSON_PRETTY_PRINT;

$log_message1 = json_encode([], MY_SIMPLE_JSON_FLAGS);
$log_message2 = json_encode([], MY_JSON_FLAGS);
$log_message3 = json_encode([], MY_JSON_LOG_FLAGS);
`

Current behaviour

Warning on all 3 json_encode() statements

Expected behaviour

No warnings (I assume that the actual values of constants can be used on analysis).
