使用PHP将数字缩写（5.2k，1.7m等）转换为有效整数 [英] Converting number abbreviations (5.2k, 1.7m, etc) into valid integers with PHP

问题描述

我有一个数据库，其中包含以速记编写的各种数字的列，例如：

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

5k for 5,000

86.6 k为86,600

4.1m为4,100,000

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

我想用这些做一些计算PHP前端的数字，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

类似的东西：

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。如果没有更多的检查需要像：

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.
}
