PHP search with spaces

[eluser]l1v1[/eluser]

Code:

public function search($key)
{
  $query = $this->db->query('SELECT * FROM upload WHERE name LIKE "%'.$key.'%"');
  $this->num_rows = $query->num_rows();
  $val = $query->result_array();
  
  return $query;
}

Why are you returning $query variable? I think you need to return the $val variable.
If you will return $val variable, then you can simply in your controller do this:

Code:

$val_array = $this->some_sort_model->search($key);
for($i=0;$i<count($val_array);$i++){
echo $val_array[$i];
}
