Codeigniter result_array（）返回一行

问题描述

在我的表中有两行，但当我 print_r $ data 它只返回db中的第二行为什么？

In my table I have two rows but when I print_r the $data that this model function is connected to it is only returning the second row in the db why?

模型功能：

function getAllUsers()
{
    $query = $this->db->get('users');

    foreach($query->result_array() as $row)
    {
        $row['id'];
        $row['fName'];
        $row['lName'];
        $row['email'];
        $row['password'];
    }

    return $row;
}

推荐答案

> $ row 是循环变量，它只保存循环退出后最后一次迭代的数据。

Because $row is the loop variable, it will only hold the data from the last iteration after the loop has exited.

：

function getAllUsers()
{
    $rows = array(); //will hold all results
    $query = $this->db->get('users');

    foreach($query->result_array() as $row)
    {    
        $rows[] = $row; //add the fetched result to the result array;
    }

   return $rows; // returning rows, not row
}

In your controller:

$data['users'] = $this->yourModel->getAllUsers();
$this->load->view('yourView',$data);

在您的视图中

//in your view, $users is an array. Iterate over it

<?php foreach($users as $user) : ?>

<p> Your first name is <?= $user['fName'] ?> </p>

<?php endforeach; ?>
