After logging in to the DedeCMS backend, click "Function Map" on the upper left
In the pop-up function map window, find the menu item "Database Content Replacement", click
Then, enter the database content replacement In the operation interface
select the dede_admin data table, then select the field userid, and then replace admin with dedechina, it’s that simple.
The above introduces the simplest method to modify the user name of the DedeCMS backend administrator, including dedecms and backend management. I hope it will be helpful to friends who are interested in PHP tutorials.
