将POST存储在新变量中或使用$ _POST

Question

Usually I call the POST method directly $_POST but if I assign the $_POST variable in new variable will the process speed faster? for example

method 1

/* $this->input->post('name') */
$this->db->where("name=".$this->input->post('name'));
$this->db->update(table, $this->input->post('name'));
$this->session->userdata(array("formdata", $this->input->post()));

method 2

$name = $this->input->post('name');
$this->db->where("name=".$name);
$this->db->update(table, $name);
$this->session->userdata(array("formdata", $this->input->post()));

Which method process faster?

Note: Sorry I don't understand how the process work in depth. I've around 30 input. Above query is just an example. There are multiple filter and processing section before sql insert/update. From what I know $_POST is a function and it take more resource than variable/array. I think using variable or array make the processing speed faster.a

Answer 1

The most efficient and better way is

Generates an update string and runs the query based on the data you supply. You can pass an array or an object to the function. Here is an example using an array:

$data = array(
        'title' => $this->input->post('title'),
        'name' => $this->input->post('name'),
        'date' => $this->input->post('date'),
      // ....... and soo ON.........
);

$this->db->where('id', $this->input->post('title'));
$this->db->update('mytable', $data);
