Functions

isValidJsonDecodeFlags()

Checks whether a given integer value is a valid combination of `json_decode()` option flags.

isValidJsonDecodeFlags(int $flags) : bool

The function compares the provided bitmask against the list of officially supported JSON_* constants for json_decode() in the current PHP version.

Note: PHP itself does not validate unknown flag bits in json_decode() — they are simply ignored. This helper ensures stricter validation.

Parameters
$flags : int

One or more JSON_* constants combined with bitwise OR (|).
