What is the difference between i remember getting the ticket and i remember to get the ticket?

Answer 1

"I remember getting the ticket" is describing something that happened in the past. For example, Sue could have lost her train ticket and she would say to her friend, "I remember getting the ticket." If she were to say, "I remember to get the ticket" it is not proper English and doesn't make sense

Answer 2

"I remember getting the ticket" suggests that the speaker recalls actually receiving the ticket in the past. In contrast, "I remember to get the ticket" implies that the speaker has a memory of reminding themselves to obtain the ticket in the future tense.
