公布一下工资管理系统中核心部分工资计算的代码

来源：互联网发布：linux expect解压缩编辑：程序博客网时间：2024/04/27 23:15

终于完成了工资计算部分的代码，请大家指教一下

用户可以自行定义工资计算公式：例如

实发工资=应发工资-应扣工资
个人所得税=tax(应发工资)

CREATE TABLE pq_unitgzxm (
   unit_id char(8) NOT NULL DEFAULT '',
   xmbh int NOT NULL DEFAULT 0,

   xtnd bit NOT NULL DEFAULT '0'
)

Go

pear RPN包中加入了tax()的自定义函数如下

'tax' => array ('tax', 3, 1, '_tax'), //hack by Daniel Summer for rcpq

    /**
     * Tax function
     *
     * @param array $temp Temporary array
     * @param integer $pos Position of operator
     * @return float Function's relult
     * @access private
     */
    function _tax($temp, $pos) {
    global $db;

    $value = $temp[$pos-1];
    $base = $db->GetOne("select * from ".TBL_TAX_BASE." where name = 'base'");

    if($value < $base) return 0; //

    $value = $value - $base;
    $rates = $db->GetAll("select * from ".TBL_TAX_RATE);


      for ($i = 0, $count = count($rates); $i < $count; $i++) {
      if($value>=$rates[$i]['bottomline'] && $value<=$rates[$i]['topline']) {
          $value = $value * $rates[$i]['rate'];
          $value = $value - $rates[$i]['quickcal'];
          break;
        }

      }


        return $value;

    }
