    runkit7_function_redefine — Replace a function definition with a new implementation

    Descrizione

    runkit7_function_redefine(
        string $function_name,
        string $argument_list,
        string $code,
        bool $return_by_reference = null,
        string $doc_comment = null,
        string $return_type = ?,
        bool $is_strict = ?
    ): bool
    runkit7_function_redefine(
        string $function_name,
        Closure $closure,
        string $doc_comment = null,
        string $return_type = ?,
        bool $is_strict = ?
    ): bool

    Nota: Per default, solo le funzioni in userspace possono essere rimosse, rinominate o modificate. Per effettuare l'override delle funzioni interne, si deve abilitare il parametro runkit.internal_override nel file php.ini.
