All the functions that serialize variables use the first element of an array to determine whether the array is to be serialized into an array or structure. If the first element has string key, then it is serialized into a structure, otherwise, into an array.
Bemærk: If you want to serialize non-ASCII characters you have to set the appropriate locale before doing so (see setlocale()).
