使用此查询，我得到了这个数组。 但是有些行与一些不同的列重复。 我想做的是将这些不同的列作为父数组的多维数组放入一个单独的数组中。我试图用Mysql group_by不同的子句来做到这一点，但我做不到。我认为最好的方法是通过php制作它。请给我一点帮助。谢谢我的查询
$query = "SELECT "
. "a.emp_nmbr, a.emp_frstNm, a.emp_lstNm, a.emp_lclFrn, b.emp_dsgntn, b.emp_dprtmnt, b.emp_allwncs, b.emp_bscSlry, b.emp_sts, c.emp_lvsCtgry, c.emp_tknFrm, c.emp_tknTo "
. "FROM "
. "employee a "
. "LEFT JOIN "
. "emp_details b "
. "ON "
. "a.emp_nmbr = b.emp_nmbr "
. "LEFT JOIN "
. "leaves_details c "
. "ON "
. "a.emp_nmbr = c.emp_nmbr "
. "WHERE emp_lclFrn = 0 ";
. "LIMIT $page, $perPage ";
代码点火器模型函数来执行查询。
function count_and_data($query) {
$query = $this->db->query($query);
$result = $query->result();
$count = $query->num_rows();
$data['count'] = $count;
$data['rows'] = $result;
return $data;
}
我得到的结果数组

这是一个快速流程，可帮助您实现要求。

);
}
