This article mainly introduces the statistical ranking and paging display functions of thinkPHP, and analyzes the operation skills related to thinkPHP database query and result paging display in the form of examples. Friends in need can refer to the following
This article analyzes thinkPHP with examples Statistical ranking and paging display functions. Share it with everyone for your reference, the details are as follows:
1. Paging parameters
| count | Total number |
| firstRow | Starting row |
| listRows | Get the number of records each time |
| list | The records of each page (it must be consistent with the count) |
2. Paging object
It can be for a real data table
It can also be for a statistically calculated data table, or a virtual table
Because LIMIT is executed last, even if you perform group operations, even if you Make a subquery

}
