Question

我正在尝试使用php开展税务计算工作。税务计算所需的平板或标准基于AGE，startincome和endincome。我正在使用CODEIGNITER框架。由于我是新手，我不知道如何完成任务。

我的代码应该只包含动态变量作为＆＃39; slabs＆＃39;要从数据库中获取，结果应根据随机给出的年龄和工资生成。

我的观点文件如下：tax.php

<form>
   <table border="1" align="center" cellpadding="30">
     <tr>
        <td colspan="2" align="center">
            <b>Tax calculation</b>
        </td>
     </tr>
     <tr>
        <td>
            <label for="name"><b>Name</label>
        </td>
    <td>
       <input id="name" name="name" type="textbox" placeholder="enter your name" size="30" >
    </td>
    </tr>
    <tr>
        <td>
           <label for="name"><b>Age</label>
        </td>
        <td>
           <input id="name" name="name" type="textbox"placeholder="enter your age" size="30" >
        </td>
    </tr>



    <tr>
       <td>
          <label for=""><b>Salary:</label></td>
       <td>
          <input id="salary" name="phone" type="textbox"placeholder="enter your yearly salary" size="30" >
    </tr>
    <tr>
       <td>
          <div>
               <input type="submit" value="calculate" name="submit" />
          </div>
       </td>
       <td>
           <label for=""><strong>Tax Amount:</strong></label>
           <input id="Tax" name="tax" type="textbox" size="17" >
       </td>    
      </table>  
 </form>

我的控制器代码如下：Tax.php

<?php

class Tax extends CI_Controller 
{

    public function __construct() 
    {
        parent::__construct();
        $this->load->helper(array('form', 'url'));
         $this->load->library('form_validation');
    }

    public function index()
    {   
        $servername='localhost';
        $username='root';
        $password='';
        $database='register';
        $conn = mysqli_connect($servername,$username,$password);
        $this->load->view('tax');
        //$this->load->model(Taxmodel);

        if(isset($_POST['submit']))
        { 
            //echo"inside submit";
            $this->form_validation->set_rules('name','Name','trim|required');
            $this->form_validation->set_rules('age','Age','trim|required');
            $this->form_validation->set_rules('salary','Salary','trim|required',array('required' => 'You must provide a %s.'));

           //checks whether the validation returns true or false
            if ($this->form_validation->run() ==TRUE) 
            {
                //echo' validation check';

                 //storing data to Array
                $userdata = array(
                'Name' => $this->input->post('name'),
                'Age' => $this->input->post('age'),
                'Salary' => $this->input->post('salary')
                );
                print_r($userdata);
                $this->load->model('Taxmodel');
                //$this->Taxmodel->insertdata($userdata);
            }

        }
    }
    public function getresult()//to get database values in a row
    {   
    echo "inside getresult";
    $salary=$_POST['salary'];
        $data= $this->db->query("SELECT * FROM `admin_income` WHERE age<".$age." and age in (SELECT max(age) FROM `admin_income` WHERE age<".$age." order by `age` desc) order by `age` desc ");
        print_r($data);                 
        $result=$conn->query($data);

        Global $totaltax;


        while ($row = mysql_fetch_assoc($result))
        {echo "inside while1";
            while($salary>= $row[$start_incom] && $salary< $row[$end_incom])
                {
                    //echo"Inside tax calculation";
                    $diff=$salary-$startincome;
                    $tax=(($percentage/100)*$diff);
                    echo $tax;
                }
            echo $tax;
        }
    }
    public function extamount()
    {//to get the additional amount to be added
        /*$query = $this->db->query("SELECT * FROM admin_income LIMIT 1;");
        if ($query->num_rows() > 0)
        {
            $row = $query->next_row('array')*/

                if($initial_income>$start_incom)//codnition for checking whether the salary exceeds first slab
                {
                    $diffresult=$end_incom-$start_incom;
                    $adtntax=[($percentage/100)*$diffresult];
                    echo $adtntax;

                }

我已尝试此代码并为我工作，您可以将其作为参考。创建范围数组 $ getTaxCharge = array（阵列（ 'amount_range_from'=＆gt; 0， 'amount_range_to'=＆gt; 250000 'tax_percentage'=＆gt; 0 ）阵列（ 'amount_range_from'=＆gt; 250001 'amount_range_to'=＆gt; 500000 'tax_percentage'=＆gt; 10 ）阵列（ 'amount_range_from'=＆gt; 500001， 'amount_range_to'=＆gt; 1000000 'tax_percentage'=＆gt; 20 ）阵列（ 'amount_range_from'=＆gt; 1000001， 'amount_range_to'=＆gt;千亿， 'tax_percentage'=＆gt;三十））;

<?php
$getTaxCharge = array(
                        array(
                            'amount_range_from' => 0,
                            'amount_range_to' => 250000,
                            'tax_percentage' => 0,
