如何在php中的字符串上求和?

问题描述

我有一个简单的问题:

我有这个变量:$v = "24000,1500,1500,1500,1500,1500,";

我想将这些数字加在一起.

i would like to add those numbers together.

我曾尝试用+和eval()来str_replace ,，但这没有用.

i've tried to str_replace the , with + and so a eval(), but that didn't worked.

我也尝试过str_split()，但它不知道在,上分开.

i also tried str_split() but it doesn't know to split on the ,.

也许如果以某种方式将其转换为数组并执行array_sum ...

maybe if somehow convert it to an array and do a array_sum...

有什么想法吗?

谢谢

推荐答案

$sum = array_sum( explode( ',', $v ) );

这是用分隔符,和 explode() 将$v拆分为$v，并将得到的零件数组求和与 array_sum() .

What this does is split $v by the delimiter , with explode() and sum the resulting array of parts with array_sum().
