How to sort it!?
- by user334269
The following is my DB data, how can I sorting it by sid and prev_sid with php/mysql!?
sid prev_sid type
000 197 app_home
197 198 page_teach
198 218 page_teach
199 211 page_step
211 207 link
218 559 page_step
559 199 page_step
Result:
sid prev_sid type
000 197 app_home
197 198 page_teach
198 218 page_teach
218 559 page_step
559 199 page_step
199 211 page_step
211 207 link
000 197 198 218 559 199 199 211 207
