### DBO Application：Delete Data When deleting data, it is recommended to perform a second confirmation to prevent mistaken deletion and data loss. DBO deletes data through conditional verification. If no condition is passed in, all data in the data table will be deleted. ####Use sql_del() to delete data ```php <?php //define the data table $table['a'] = 'admin_user';//administrator table $table['b'] = 'admin_group';//administrator group table $ljoin['b'] = 'b.id=a.gid';//associated conditions $t_field = 'a.id,a.nickanme,b.group_name';//query field //delete data sql_del(array('table'=>$table['a'],'where'=>'id!=1')); //close the database $db->close(); ?> ```
