本文介绍php四舍五入函数使用方法，php 数据处理之取整,四舍五入分为四个部分，php四舍五入函数使用分别如下。

1.丢弃小数部分,保留整数部分  

intval(7/2)
Copy after login

2.向上取整,有小数就整数部分加1 

ceil(7/2)
Copy after login

3, 对浮点数进行四舍五入 

round(7/2)
Copy after login

如果php四舍五入要保留两位小数，后来参数根保留小数位数即可。

$number = 1234.5678;
echo round($number ,2); //1234.57
Copy after login

4,向下取整 

floor(7/2）
Copy after login
