今天是值得高兴的一天，什么原因呢。

原来写的一段程序，很糟糕，自己都不愿意看了。今天思考了一上午，推翻原来的思路，按照新的方法重新

构造了一下，两三个小时写完了，很happy.

这是一个计算房租的方法，三个月交一次房租，房租根据园区所在地有增长率，超过了设置的年数，单价就要上涨

原来写的方法用了过多的if else，自己看着也头疼，bug也很多，不足年或不足三个月价格就很难算出来，现在的新方法，

只要有了开始时间和结束时间，房租都会准确的计算出来。

现在的思路是不管房租从何时签，何时结束，不管是否足年，是否足月。大的方向分两种足月（三个月为一计算单位），不足月。

$start = $arrLeaseAccountData['LEASE_START']; //合同鉴定开始时间

$end = $arrLeaseAccountData['LEASE_END']; //合同鉴定结束时间

//租赁合同总共的月数

$month = round((strtotime($end)-strtotime($start))/30.4/24/3600);

//开始年

$startYear = date('Y', strtotime($start));

//开始月份

$startMonth = date('m', strtotime($start));

//开始天数

$startDay = date('d', strtotime($start));

//单价

$price = $arrLeaseAccountData['RENT_PRICE'];

//补充折扣

$priceRate = $arrLeaseAccountData['DISCOUNT_RATE']!=''?$arrLeaseAccountData['DISCOUNT_RATE']:0;

//实际价格

$nowPrice = $priceRate!==0?round($price * ($priceRate/100), 2):0;

//面积

$area = array_sum($arrLeaseAccountData['ROOM_AREA']);

//递增年

$year = $arrLeaseAccountData['RENTAL_GROWTH_YEAR'];

//递增率

$rate = $arrLeaseAccountData['RENTAL_GROWTH_RATE'];

//补充协议的免租期(天)

$period = $arrLeaseAccountData['FREE_RATE_PERIOD']!=''?$arrLeaseAccountData['FREE_RATE_PERIOD']:0;

//租赁合同的免租期(天)

如果再细细的分析一下，该方法还可以再改进。
