PHP房贷计算器实例代码,等额本息,等额本金

前端之家收集整理的这篇文章主要介绍了PHP房贷计算器实例代码,等额本息,等额本金前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

实例如下:

PHP;"> debx();

function debx()
{
$dkm = 240; //贷款月数,20年就是240个月
$dkTotal = 10000; //贷款总额
$dknl = 0.0515; //贷款年利率
$emTotal = $dkTotal $dknl / 12 pow(1 + $dknl / 12,$dkm) / (pow(1 + $dknl / 12,$dkm) - 1); //每月还款金额
$lxTotal = 0; //总利息
for ($i = 0; $i < $dkm; $i++) {
$lx = $dkTotal * $dknl / 12; //每月还款利息
$em = $emTotal - $lx; //每月还款本金
echo "第" . ($i + 1) . "期"," 本金:",$em," 利息:" . $lx," 总额:" . $emTotal,"
";
$dkTotal = $dkTotal - $em;
$lxTotal = $lxTotal + $lx;
}
echo "总利息:" . $lxTotal;
}

function debj()
{
$dkm = 240; //贷款月数,20年就是240个月
$dkTotal = 10000; //贷款总额
$dknl = 0.0515; //贷款年利率

$em   = $dkTotal / $dkm; //每个月还款本金 
$lxTotal = 0; //总利息 
for ($i = 0; $i < $dkm; $i++) { 
  $lx   = $dkTotal * $dknl / 12; //每月还款利息 
  echo "第" . ($i + 1) . "期"," 总额:" . ($em + $lx),"<br />"; 
  $dkTotal -= $em; 
  $lxTotal = $lxTotal + $lx; 
} 
echo "总利息:" . $lxTotal; 

}

exit;
