使用 PHP 将数字缩写(5.2k、1.7m 等)转换为有效整数

2022-01-17 00:00:00 numbers integer php

我有一个数据库，其中有一列包含用速记"书写的各种数字，例如:

I have a database with a column containing a variety of numbers written in "shorthand", for example:

5k 换 5,000
86.6k 换 86,600
4,100,000 为 4.1m
1.2b 为 1,200,000,000

5k for 5,000
86.6k for 86,600
4.1m for 4,100,000
1.2b for 1,200,000,000

我想用这些数字为 PHP 前端做一些计算，但我需要将它们转换为有效的整数才能这样做.我怎么能用 PHP 做到这一点?

I'd like to do some calculations with these numbers for a PHP frontend, but I need to convert them into valid integers in order to do so. How could I do this with PHP?

推荐答案

类似:

switch (strtolower(substr($input, -1))) {
        case 'k':
                $input*=1000;
                break;
        // similarly for m, M, b, B.
}

假设您的数据格式正确.如果不需要更多检查，例如:

Assuming your data is well-formatted. If not more check would be needed like:

if (!preg_match('/^d+(?:.d+)?[mbk]$/i',$input)) {
   // $input is not a valid format.
}
