This article analyzes the thinkphp statistics ranking and paging display function. Share to everyone for your reference, specific as follows:
1. Paging parameters
| Count | Total |
| FirstRow | Start line |
| ListRows | Get the number of records per time |
| List | The records for each page (to match the count) |
2. Paging objects
Can be used for real data tables.
You can also focus on a statistically available datasheet, or virtual table.
Because limit is the last execution, even if you do a group operation, even if you do subquery
