codeigniter中子句中的多列where_

假设您的数据数组是这样的(应该是这样的)

$val1 = array(1,2);
$val2 = array(2,3);

$this->db->select('*');
$this->db->from('tab1');
$this->db->where_in('col1',$val1);
$this->db->or_where_in('col2',$val2);
$query = $this->db->get();
$result = $query->result_array();

$this->db->query("select * from tab1 where (col1,col2) in ($val1,$val2)");

“$arr\u 1=some\u数组;”

“$arr\u 2=一些数组;”

如果它们是相同的阵列,只需替换 $array_2 具有 $arr_1

$result = $this->db->select('*')->where_in('col1',$arr_1)->where_in('col2',$arr_2)->get('tab1')->result_array();

$result = $this->db->select('*')->where_in('col1',$arr_1)->or_where_in('col2',$arr_2)->get('tab1')->result_array();
