PHP Code:

StringMap g_map;
StringMapSnapshot g_mapsnap;
void CreateStringMap()
{
    g_map = CreateTrie();

    g_map.SetString("a","11111");
    g_map.SetString("b","11111");
    g_map.SetString("c","11111");
    g_map.SetString("d","11111");

    g_mapsnap = g_map.Snapshot();
} 


i try something like this，but when i use snap.GetKey() from 0 to snap.length , it comes with c a b d , not a b c d.
Is there something wrong?

the order doesn't matter much if you are using a StringMap, but still curious

Maybe this:

CreateTrieSnapshot Function Creates a snapshot of all keys in the map. If the map is changed after this call, the changes are not reflected in the snapshot. Keys are not sorted.
