* Bitmask of JSON decode options:
* {@see JSON_BIGINT_AS_STRING} decodes large integers as their original string value.
* {@see JSON_INVALID_UTF8_IGNORE} ignores invalid UTF-8 characters, * {@see JSON_INVALID_UTF8_SUBSTITUTE} converts invalid UTF-8 characters to \0xfffd, Available as of PHP 7.2.0. * {@see JSON_OBJECT_AS_ARRAY} Decodes JSON objects as PHP array. This option can be added automatically by calling json_decode() with the second parameter equal to true. * {@see JSON_THROW_ON_ERROR} Throws JsonException if an error occurs instead of setting the global error state that is retrieved with json_last_error() and json_last_error_msg().
