5. If ($ secret = "on ")
6. {
7. // Mark the speech + Indicates the delimiter.
8. // The first one marked as secret indicates private chat, followed by the chat object and its own name, so that the two can see
9. $ Message =" Password $ message ";
10. }

15. }

2. // Separate the speech content
3. $ Tempmessage = split ($ split, $ message [0], 99 );
4. // If the speaker is not a private conversation, or the target user is a private chat, or the user who sends the private chat is himself, this sentence is displayed; otherwise, it is not displayed.
5. If ($ tempmessage [1]! = "Secret") | ($ tempmessage [2] = $ name) | (
6. $ Tempmessage [3] = $ name ))
7. {
8. // Display private chat
