Make an approval list from Database online

Greetings to all
I am making an App where in the first place I will register user eg (name,sexe, âge phone) then store the user’s data in phpmy admin database then I will need to retrieve the information previously save and display them in a list that I will call approval list and from there I have to select a user then complete the registration then save it finally and after saving it has to disappear from the approval list and so only those user not yet approved that will be left in the approval list
Please help
