Question

如何从以下查询中获取id的值

$id = $this->db->query("SELECT id from tbl_profile_main WHERE token_='".$token."';");

Answer 1

尝试：

$row = $id->row();
echo $row->id;

Answer 2

要从选择查询中回显id，请使用->row()

$query = $this->db->query("SELECT id from tbl_profile_main WHERE token_='".$token."'"); 

$id = $query->row();
echo $id->id;// will echo only id one time

Answer 3

$query = $this->db->select('id')->where(array('token_'=>$token))->get('tbl_profile_main');

if($query->num_rows()>0{



//if multiple rows
 $result = $query->result_array();
  foreach($result as $id){

    echo $id['id'];

  }

   //if one row

    //  $id = $query->row();
   // echo $id->id;



}

Answer 4

尝试

$query = $this->db->query("SELECT id from tbl_profile_main WHERE token_='".$token."';");
$row = $query->row();

if (isset($row))
{
   echo $row->id;        
}

对于倍数结果

$query = $this->db->query("SELECT id from tbl_profile_main WHERE token_='".$token."';");

foreach ($query->result() as $row)
{
   echo $row->id; // Echo id of all result and retun as object         
}

Answer 5

如果有一行：

$id = $id->row_array()['id'];

如果有多行：

foreach($id->result_array() as $ids) {
  print $ids['id']; // or save to an array or whatever you please
}
